[osg-users] Question about libtiff usage
Hi, all. I see that libtiff is a dependency of OpenSceneGraph. Does anyone know what function it provides and if OSG will work if libtiff.dll is removed?

[osg-users] Textured PointSprites broken when upgrading from 3.5.6 to 3.6.2
Hi,
We recently upgraded OSG from 3.5.6 to 3.6.2 and our textured PointSprites
stopped working.
In a debug build they work fine but in a release build they do not display or,
if they do, they display using a translucent version of the non-textured points
which flash on and off as we navigate the scene.
The code is based on the osgpointsprite example - which we cannot get to fail.
The code is used by several features all of which have the bug. If we strip it
down to just one feature using this code then it still has the bug. If we
strip out the textures then default Points work fine on all features.
Using hard-coded textures instead of loading them from files does not help.
We have tried just about everything we can think of and are about to switch to
a combination of non-textured points, billboards & simple geometries as a
workaround.
Code:
addPointSprite(mModel.base().dataPaths.resourcesPath(),
PointSpriteShapes::Diamond,
NodePointSizeLarge,
NodePointSizeSmall,
NodePointSizeLarge,
mNodesGeometry);
const std::map PointSpriteFileNames = {
{PointSpriteShapes::Circle, "Circle.png"},
{PointSpriteShapes::Diamond, "Diamond.png"},
{PointSpriteShapes::Square, "Square.png"},
{PointSpriteShapes::MarkerRouteStart, "MarkerRouteStart.png"},
{PointSpriteShapes::MarkerRouteBroken, "MarkerRouteBroken.png"},
{PointSpriteShapes::MarkerRouteEnd, "MarkerRouteEnd.png"},
};
void
addPointSprite(const std::string & aResourcesPath,
PointSpriteShapes aSpriteShape,
float aStartingSize,
float aMinSize,
float aMaxSize,
osg::Node * aNode)
{
Expects(PointSpriteFileNames.find(aSpriteShape) !=
PointSpriteFileNames.end());
auto stateset = aNode->getOrCreateStateSet();
osg::ref_ptr sprite = new osg::PointSprite();
sprite->setCoordOriginMode(osg::PointSprite::LOWER_LEFT);
stateset->setTextureAttributeAndModes(0, sprite, osg::StateAttribute::ON);
auto texture = createTexture(aResourcesPath,
PointSpriteFileNames.at(aSpriteShape));
stateset->setTextureAttributeAndModes(0, texture, osg::StateAttribute::ON);
osg::ref_ptr point = new osg::Point();
point->setSize(aStartingSize);
point->setMinSize(aMinSize);
point->setMaxSize(aMaxSize);
if (aMaxSize > aMinSize)
{
point->setDistanceAttenuation(osg::Vec3{1.0f, 0.001f, 0.0f});
}
stateset->setAttribute(point);
}
inline osg::ref_ptr
createTexture(const std::string & aResourcesPath, const std::string &
aImageName)
{
const auto imagePath = aResourcesPath + "/images/" + aImageName;
return new osg::Texture2D(osgDB::readRefImageFile(imagePath));
}
Are you aware of any issues with textures point sprites in 3.5.6, or can you
see what we are doing wrong?
Thanks,
Brian[/code]

Re: [osg-users] DXF file with text crashes on Intersect
Hi Robert, I have tried in the latest release and unfortunately the bug is still there. I will try and put together some test code, we are in the middle of our own release bugfix cycle at the moment so it may take a while. In the meantime (in case you already have something which views DXF files and lets you pick) here is a DXF file which has this issue. Zooming in around the center you should find some text labels and picking over some text should trigger the crash.

[osg-users] DXF file with text crashes on Intersect
Hi,
We are using osg version 3.5.6 from VCPKG.
When we load a DXF which includes text it loads and displays fine. However if
we then call GUIActionAdapter::computeIntersections on the scene whilst the
mouse is over a piece of text within the loaded DXF it crashes here:
Code:
void Text::accept(osg::Drawable::ConstAttributeFunctor& af) const
{
if (_coords.valid() )
{
af.apply(osg::Drawable::VERTICES, _coords->size(), &(_coords->front()));
af.apply(osg::Drawable::TEXTURE_COORDS_0, _texcoords->size(),
&(_texcoords->front())); <<<<<<<<<<<<<
}
}
_texcoord would appear to be empty.
We are simply loading the DXF via readRefNodeFile then placing them in a
PositionAttitudeTransform within out scene.
I can work around it for now as we do not want the loaded DXF's to be directly
pickable so can exclude them via a NodeMask, but would prefer not to have to do
so.
I see that there is a more recent build of osg available - is this something
which has been fixed since 3.5.6?
I can post a copy of an affected DXF if it would help.
Thank you!
Cheers,
Brian[/code]

Re: [osg-users] Problems with osgText::Text internal transformations and LineSegmentIntersector
Hi Robert, Thanks for the quick response. I will give that a try at some point and let you know if it helped. Do you have a timescale for the release of 5.6.0? Thanks, Brian -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=73141#73141 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Problems with osgText::Text internal transformations and LineSegmentIntersector
Hi,
When I use any of the following methods to reposition osgText::Text the picking
fails when used with LineSegmentIntersector.
Code:
text->setPosition() // anything other than {0.0,0.0,0.0}
text->setRotation() // anything other than osg::Quat(0.0, osg::Z_AXIS)
text->setAlignment() // anything other than LEFT_BOTTOM
As far as I can work out from debugging, the bounds are being correctly
calculated and "intersectAndClip" is returning true. The problem seems to be
when "drawable->accept" is called in the "intersect" method, the
IntersectFunctor does not have the transformations that Text is using and the
vertices passed to it are not transformed.
The only way I can find around this is to place the text inside
PositionAttitudeTransform's and do the positioning myself. Unfortunately,
since I do not know the eventual dimensions of the text, doing a CENTER_CENTER
alignment is practically impossible.
If I leave the alignment to be done by Text then a CENTER_CENTER alignment
means that you can only pick the top left quarter of the text.
I have tried placing the text inside either a Geode or a Group but it makes no
difference.
I would be very happy if I was simply not calling something I should be to
initalise the Text or its container correctly.
We are using OSG 3.5.6 statically linked via VCPKG.
Any help gratefully received,
Thanks,
Brian[/code]

Re: [osg-users] Enable, Disable Multible Shaders
Hi, Thank you for the reply. I actually found another solution that was a better solution than turning off shaders by the stateset. Originally, I just wanted to turn off shaders for a stateset so that the objects in that stateset would not cast a shadow. I though that this would work because the entire scenegraph has been created in a way so that all objects displayed are rendered through a shader. I did some research and found out there was a way to disable shadows in the scenegraph. I was skeptical at first that this would work but turning off the bit for casting shadows worked. It was a lot more elegant solution to use than turning off shaders for the object. I tried putting in an empty program object and that didn't work. This was the only thing that worked. Thank you!

Re: [osg-users] Enable, Disable Multible Shaders
Hi, I having a similar problem with stateset. I have a program where all the geometry has a shader attached at the point of loading. There is one object in this entire database of objects that have shaders attached to it somewhere and is causing this object to cast a shadow based on a singular shader based light source. I tried to solve this problem by disabling the PROGRAM state attribute but disabling doesn't seem to prevent it from casting a shadow. I don't understand though. I can get the node for these objects and derive the state sets from those nodes but I can't seem to disable the object from casting a shadow. Someone told me that there are attributes on textures and geometry that allow you to make it so that texture or geometry doesn't cast a shadow. Thank you!

[osg-users] Attempting X11 (lib issue) and Windows (GLfloat issue) compiles forOSG in Cygwin
I attempted to get OSG to compile in Cygwin and I finally got an X11
version to compile. I had problem with osgViewer which did not seem to
want to add the libraries X11 and Xrandr even though it saw them. I
could add the libraries to link.txt for the modules that failed and
then execute and they would compile. I tried determining what was
wrong with the CMakeLists.txt for osgViewer but only way I could get it
to add the X11 and Xrandr was to change this routine near the end:
IF(MINGW OR CYGWIN)
SET(TARGET_EXTERNAL_LIBRARIES ${TARGET_EXTERNAL_LIBRARY} gdi32 )
ENDIF()
so that the set line reads as follows:
SET(TARGET_EXTERNAL_LIBRARIES ${TARGET_EXTERNAL_LIBRARY} gdi32
${X11_X11_LIB} ${X11_Xrandr_LIB} )
And then compiled great and worked.
I then tried to get it to compile without X11 by setting
OSG_WINDOWING_SYSTEM to none and it compiled but osgViewer could not
create a window so then I change the GL references to point to the
opengl libs in w32api for cygwin which as I recall is the appropriate
think to do so it uses the win opengl libs and includes. But now when
compiling I get this error regarding GLfloat and GLdouble

Re: [osg-users] building for xcode on os x
I'm not using make I'm using xcode, so I'm not sure how that would be done if
it's possible
I tried building in make and couldn't figure out how to set it to build for 32

Alright I got it working in Xcode now, for the osgdb_jp2 target I added the
following to the header search path:
/opt/local/include
The search path /opt/local/include/jasper was already on the search path from
cmake, but the #include's in the jasper.h start with jasper/some_file.h, so
it needs the directory above to find the jasper directory
However when I build the install target I get the following error:

I installed jasper using Macports and it installed ok, i checked by running
jasper --version and got:
1.900.1
libjasper 1.900.1
However in xcode i'm still getting the same compilation errors. I even
deleted the build folder and started the whole configure generate process in

Re: [osg-users] building for xcode on os x
I set to generate makefiles and the jasper directory appears to be set
correctly to the /Library/Frameworks/libjasper.framework/Headers/jasper folder.
However now I'm getting the following errors:

Re: [osg-users] building for xcode on os x
Alright I got it working in Xcode now, for the osgdb_jp2 target I added the
following to the header search path:
/opt/local/include
The search path /opt/local/include/jasper was already on the search path from
cmake, but the #include's in the jasper.h start with jasper/some_file.h, so
it needs the directory above to find the jasper directory
However when I build the install target I get the following error:

[osg-users] How do I get osgviewer on Cygwin to compile with -lX11 -lXrandr
I tried building OSG on Cygwin 1.7 and I first tried to do it without X but it seems that osgviewer seems to insist on X11 and that WIN32 option has been removed (or is that what you get if you leave it at none). At any rate I finally accepted the defaults (except adding -DNOMINMAX and was bale to get osg to build but to get edit several link.txt files during the build. I ran Cmake and did the configure and generate and then each time it bombed using something involving osgviewer then I would go edit the appropriate link.txt file and add -lX11 -lXrandr to the executable line in that file and then execute the file. This would complete the link and then when I started my make again it would move past that build and continue. I did this for each link failure as follow: In the build directory for OSG (my build root is /usr/develop/obj/osg): /usr/develop/obj/osg/src/osgViewer I edited the file: vi ./CMakeFiles/osgViewer.dir/link.txt and added the -lX11 -lXrandr to the line in link.txt. I then executed the link.txt file as in : ./CMakeFiles/osgViewer.dir/link.txt and the file built - so that was all it needed for osgViewer but... I then would have to do this other parts of the build (osgArchive, osgConv and so on ) to get it to finish. My question(s) is/are where do I find the logic that dictates during the Cmake configure what libs to include and in what files will I find this when the generate finishes. I would like to tweak this so the cmake configure and generate for cygwin was smart enough add the X11 and Xrandr libs. I would also like to know (if any knows) what in general should be the setting to get osgviewer to build without X11 on Cygwin and just use the opengl and no X. thanks bk ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Will OSG handle RAS to some other format before I try to get it to compile in Cygwin
A year or so back I was able to get OSG to compile on Cygwin. Recently tried again and I am having a few issues. Of course in the meantime I have moved from Cygwin 1.5 to 1.7 and that has major changes plus the GCC/G++ 4.3.4 compiler and changes within that to create the cross compiler as opposed to the old -mno-cygwin switch. Any or all of these factors may be an issue. I've tried following my old notes but if I accept the CCMake defaults where it finds X and OpenGl then it burps n Xsync and others which are in the X libs and present on my system and in the cmake. If I try to make it a Windows appl and viewer then it burps on the _gl??? References. Before I spend any more time on this I wanted to verify that OSG can convert a RAS image file to a bmp or jpeg or something. We have some RAS images we tried to get from an AS400 for forms design but we need to get them back into another format to edit them and proceed. Other programs I have tried tell me invalid/incorrect header. Thanks for any assistance. bk ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Hi, I noticed that at least with the Collada and OBJ writer plugins for osgconv, the original material names do not seem to be used in the output. Instead, generic names are used. If I use osgconv to output to .osg or .json (plugin from the osgjs website), the original material names are in the output as expected. I also tried setting the notify level to 'DEBUG' when running osgconv, but I didn't see any errors or warnings regarding the materials. If it matters, the input file is a 3ds model (I've also verified that lib3ds reads the material names properly). Thank you!

[osg-users] Using a manipulator to follow a moving object
Hi, I'm working on an application where the initial scene is scene is very large. However, as the user adds smaller objects to the scene I want the camera to be able to follow the objects. I'd like to be able to center the manipulator on an object and follow the object along a path. I'm trying to use the orbitalManipulator's setTransformation function to do this by calculating an eye vector (based on a North East Down offset from the center and rotation back to X,Y,Z), a center (the object's position), and an up vector (the unit vector of the object's position). I can run the model and printout what appear to be valid vectors for the eye, center, and up, but the camera appears to be looking at my object from the wrong direction. Does my approach seem logical, and is there some obvious coordinate conversion that I'm not doing to go between global (x,y,z -model coordinates) to viewing (cameraManipulator) coordinates? ViewerQT* canvas; canvas-getCameraManipulator()-setTransformation(eye, center, up); Thank you!

[osg-users] osgmovie and gif files
When I load an animated gif file into osgmovie demo, the movie plays fine.
However, the '+' key slows the movie down, and the '-' key speeds the movie up.
Why are the keys backwards? I am using osg 2.8.3 on windows.
Also, in the demo, why is the pointer returned by the osgDB::readImageFile
casted to an ImageStream as opposed to an ImageSequence (it failes to cast to
an ImageSequence)? I guess I'm not sure what the difference between the two
are. The implementation for the speed up and down are missing in the
ImageStream class:
Code:
virtual void setTimeMultiplier(double) {}
virtual double getTimeMultiplier() const { return 0.0; }
but the implementation is present in the ImageSequence class:
Code:
virtual void setTimeMultiplier(double tm) { _timeMultiplier = tm; }
virtual double getTimeMultiplier() const { return _timeMultiplier; }
ImageSequence is the only class I see that inherits from ImageStream.
Thanks,
Brian

Re: [osg-users] viewer-removeSlave does not make HUD visibly disappear
I found the problem. I had a reference pointer to my camera which prevented the camera from getting deleted by the removeSlave function. I didn't want to delete the camera, so I just did Code: cameraHUD-setViewport(NULL); which worked. Then I could set the viewport again when I wanted the HUD to reappear. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=32367#32367 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Rendering left right stereo frames in separate threads?
I have switched to point sprites and performance is over 10X better! However,
I had to do much research to get point size to match world unit sizes, as well
as transparent textures and depth sorting to create spheres. Here is what I
did:
I used a shader to calculate point size:
Code:
m_stateSet-setMode(GL_VERTEX_PROGRAM_POINT_SIZE,osg::StateAttribute::ON);
const char* vertSource = {
uniform float windowHeight;\n
uniform float particleRadius;\n
void main(void)\n
{ \n
gl_TexCoord[0] = gl_MultiTexCoord0;\n
gl_FrontColor = gl_Color;\n
gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;\n
vec4 mod = gl_ModelViewMatrix *
gl_Vertex;\n//http://lumina.sourceforge.net/Tutorials/Point_sprites.html
//http://www.terathon.com/gdc07_lengyel.ppt
//gl_ProjectionMatrix[1][1] = e/a where:
// e = focal length = 1 / tan(FOV / 2)
// a = viewportHeight / viewportWidth
gl_PointSize = particleRadius * gl_ProjectionMatrix[1][1] * windowHeight/
-mod.z ; \n
} \n
};
const char* fragSource = {
uniform sampler2D tex;\n
void main(void)\n
{\n
vec4 texel = texture2D(tex,gl_TexCoord[0].xy);\n
gl_FragColor = gl_Color * texel;\n
}\n
};
I disabled GL_LIGHTING.
I set up transparency:
Code:
m_stateSet-setMode(GL_DEPTH_TEST, osg::StateAttribute::ON);
m_stateSet-setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
m_stateSet-setRenderBinDetails( 0, RenderBin);
m_stateSet-setMode(GL_BLEND, osg::StateAttribute::ON);
m_blendFunc = new osg::BlendFunc();
m_blendFunc-setFunction(osg::BlendFunc::SRC_ALPHA,
osg::BlendFunc::ONE_MINUS_SRC_ALPHA);
m_stateSet-setAttributeAndModes(m_blendFunc, osg::StateAttribute::ON);
I enabled point sprites so that my texture would show up:
Code:
m_pointSprite = new osg::PointSprite();
m_stateSet-setTextureAttributeAndModes(0, m_pointSprite,
osg::StateAttribute::ON);
I sorted all points by greatest distance from the camera eye vector to each
point's origin. I sorted the points (vertices) using std::sort
Thanks

[osg-users] viewer-removeSlave does not make HUD visibly disappear
I created an HUD with the following code:
Code:
//SETUP HUD
m_rootHUD = new osg::Group();
// create a camera to set up the projection and model view matrices, and the
subgraph to drawn in the HUD
m_cameraHUD = new osg::Camera;
// set the projection matrix
m_cameraHUD-setProjectionMatrix(osg::Matrix::ortho2D(0,1280,0,1024));
// set the view matrix
m_cameraHUD-setReferenceFrame(osg::Transform::ABSOLUTE_RF);
m_cameraHUD-setViewMatrix(osg::Matrix::identity());
// only clear the depth buffer
m_cameraHUD-setClearMask(GL_DEPTH_BUFFER_BIT);
// draw subgraph after main camera view.
m_cameraHUD-setRenderOrder(osg::Camera::POST_RENDER);
// we don't want the camera to grab event focus from the viewers main
camera(s).
m_cameraHUD-setAllowEventFocus(false);
m_cameraHUD-addChild(m_rootHUD);
osgViewer::Viewer::Windows windows;
m_viewer-getWindows(windows);
if (windows.empty())
{
std::cout error: no windows\n;
exit(1);
}
// set up cameras to rendering on the first window available.
m_cameraHUD-setGraphicsContext(windows[0]);
m_cameraHUD-setViewport(0,0,windows[0]-getTraits()-width,
windows[0]-getTraits()-height);
Then I add some stuff to the group root node. Then I add the camera to the
viewer with the following code.
Code:
unsigned int slaveID = m_viewer-getNumSlaves();
m_viewer-addSlave(m_cameraHUD, false);
Now, when I decide I want to remove the HUD with the following code, it removes
but the HUD is still visible.
Code:
if (!m_viewer-removeSlave(slaveID))
{
std::cout error removing slave slaveID \n;
exit(1);
}
Shouldn't that command remove the HUD from the screen?
Thank you

Re: [osg-users] Blending Multiple Texture on one triangle mesh with coordinate control
Hi Alberto Thank you very much for your quick response. One of the reason our team has to do it via open scene graph is because our program has to modified the triangle mesh in real time, this include additional or removal or triangles. Therefore, (I may be wrong, because i m very new to 3D graphic) we can not do it via Blender or 3dMAX. Do you know if any function in osg i should look into to do that function?

Re: [osg-users] Rendering left right stereo frames in separate threads?
Thanks for your help Robert. I think I will take your advice as to seeing why my app is so cpu limited. I am doing a 600 particle simulation using the bullet physics library. Therefore, I have 1 geometry, 600 geodes, 600 materials, and 600 Positionattitudetransforms. The shared geometry and the materials are attached to the geodes which are then attached to the PAT's. The application runs in real time, and every frame each sphere position and material color changes. I do all the physics stuff and the updating of the positions and materials in a separate thread. So the main OSG thread just runs viewer.frame() with no node update callbacks. I am running the viewer in single threaded mode. I profiled the main thread and find that most of the time spent is in osg::group::computebound and osg::matrixd::premult, premulttranslate, postmult, etc. Is there maybe another structure other than Positionattitudetransform that I can use where I can do all the matrix computations in my other thread so that viewer.frame() doesn't have to do them?

BIND_PER_PRIMITIVE will apply the attribute per primitive in you case per triangle. Tex coords in the OSG are always bound per vertex, there isn't a control to alter this. If you have a vertex array and indices for your triangles the natural thing to do would be to use a osg::DrawElementsUShort(GL_TRIANGLES) then use push_back(tri.p1) for each index on each triangle. I would suggest binding the normals per vertex, you'll have to do this for the tex coords as well. If a single vertex will have multiple tex coords or multiple normals associated with it due to differences in the triangles then you'll need to duplicate the vertices and remap the indices on the triangles to fit this.

Re: [osg-users] FBX Plugin: animation speed not as expected...
Hi Alessandro and Michael, I have similar timing-related playback errors on a multi-take FBX exported from MotionBuilder. Playback in: OSG 2.9.8 OSG FBX plugin built with: FBX Sdk 2011.2: fbxsdk_md2005.lib / fbxsdk_md2005d.lib FBX exported from: MotionBuilder 2011 QuickTime can move between all twenty(ish) animation takes and play them with proper timing. The only oddity is that after each animation plays, there is a variable length dead space on the playback timeline in which the model does not move. For example, the first 40% of playback is animated normally, then it stays in a static pose for the remaining 60% of the timeline. Playback is different using the osgViewer modified for FBX playbacks and changing takes/animations when a key is pressed. Calling playAnimation() moves the character to the correct initial pose but he does not move. In the debugger, the animation durations appear correct (e.g., 12 seconds) but for most takes the model is motionless the whole time. For a few takes, after a long pause the model eventually runs part of the animation at very high-speed, in the way that Alessandro's 3-bouncing-balls model played at high speed. Then even these return to a static pose for the remainder of their play time. My best guess is the timing is thrown off and this is somehow compounded across takes. The plugin has FPS hard-coded to 25 fps so we tried exporting at both 25 fps and 30 fps with only slightly varying results. I can email a sample file to demonstrate this (~15 MB).

Re: [osg-users] Would someone be willing to help me diagnose a performance issue?
At the highest level: Update - cpu processing your application is performing Cull - cpu processing performed by osg in traversing the scene graph and packaging drawing state Draw - cpu processing for sending drawing state to gpu and gpu processing of the drawing state If Update stage is large, you need to determine what part of your application is taking the time and optimize it. If Cull stage is large the scene hierarchy is too complex and needs to be optimized - spatial optimization, flatten static hierarchies, ... If Draw stage is large then you need to determine if you are vertex or pixel limited. If you grab the window corner and shrink/expand it's size and the performance increases/decreases significantly, then you are pixel/fill limited (too much depth complexity/too much pixel processing). If the performance doesn't change then you are probably vertex/transform limited (too many verts/too much vertex processing). It's actually much more complex than this, but it's how I start diagnosing performance issues. Run your scene in osgViewer to see how fast it renders. You might have to build the scene in your regular app and then save the scene root to an .ive file, which you can load into osgViewer. A really good tool to use is an OpenGL command logger. It logs all the actual OpenGL commands that OSG is issuing and can help identify problem areas.

Hello, I have two applications, both of which are displaying basically the same scene. One application runs at 230+ fps while the other runs at about 45 fps. I'm trying to figure out what is causing this performance difference. Using high-precision timers, I've been able to determine that the difference occurs somewhere in the rendering of the scene graph, but I'm not 100% sure where. I have a couple of ideas, but each will take some amount of time to investigate, and so I was hoping someone might be able to lead me towards the most-correct answer. The first idea I had concerns differences in how the scene graphs are structured in each application. The quick app works simply by loading the three models that it needs (from FLT files, so these 'models' are in fact complex sub-graphs) and attaches them to the root node, and sets that root node as the scene data. The slow app loads every model that could possibly ever be used (52 in all, and again each 'model' could actually be a complex sub-graph). These 52 nodes are then attached to the root, and their visibility is turned off by setting their node mask to 0. Then, if the user of the application wants to see a model, the app will copy the node (and all of it's children) and then add this copy to the scene root group, with the visibility turned on. This way, if the user of the app wants to populate the scene with many instances of the same model, they can do so, because each time they do it, a separate copy of the node is made. I realize that there are a lot of things that can be done to make the slow app more memory-efficient. For instance, it could use lazy loading to load a model only when it is needed (although this may cause a noticeable delay, but that would probably be fine). And if the user wants to see several instances of this model, this could be accomplished without copying the model's entire subgraph. Instead, we could simply create a new matrix transform, and add THAT to the root, and add the model's node as a child of this new matrix transform (at which point, the model's node will have more than one Matrix Transform parent). However, these issues seem to pertain more towards memory efficiency than rendering efficiency, so I'm not sure if this is going to solve my immediate problem (although it is almost certainly something I will implement later on). Related to this, I was wondering if anyone had an explanation as to what the Camera / View statistics referred to. I read the Quick Start Guide, and it had excellent information about the Event/Update/Cull/Draw/GPU chart at the top of the statistics screen, but I'm not exactly sure what the statistics in the Camera / View windows refer to. For instance, does the Vertices stat refer to the total number of vertices in all of the drawables, whether those drawables are visible or not? The reason I ask is that, in terms of these statistics, both the Quick App and the Slow App have nearly-identical numbers in the View section, but in the Camera section, the Slow App's numbers are way, way, way higher. I wonder if this tells me something about how to optimize the Slow App to bring it up to speed. The other major difference I noticed was in the threading model.

The removeTextureAttribute method is called, but I can still see the textures on the meshes. Is this the correct way to remove the textures? Keep in mind that Drawables also have a stateset which you won't get to by using the code you posted. So in addition to removing the textures on all statesets assigned to nodes, you also need to override apply(Geode) and loop through all Drawables and remove the textures there too. If that still doesn't work, then you could use osgDB::writeNodeFile() after running the visitor, to output the resulting subgraph to a .osg file which you can load in a text editor to see where the remaining textures are.

Hi Robert, My comment Not sure why it did that was about why the complex app wanted to set the transparency, not why it changed the performance. Once I found it I understood what it was doing - render order based on distance from camera instead of order based on optimized state. BTW - kudos to the developers of bugle. I've never used an opengl trace logger before and was really excited about the insight it provides. Thanks for your help.

Setting hint to drop the geometry into transparent bin - which is depth sorted rather than state sorted will break state sorting, so you'll end up with many more state changes that incur greater CPU load on draw traversal and load down on the GPU.

[osg-users] Rendering Optimizations Not Working
Folks, I'm rendering a scene with 3 different objects instanced 500 times each. When I run it in osgviewer is achieves 1000 hz, when I run it in a simple osgViewer::Viewer based app it runs at 1000 hz, when I run it in a more complex osgViewer::Viewer based app it runs at 30 hz. All the additional time is in the draw process. I used bugle to capture the opengl output (bugle is fantastic!) from the 3 apps and the first two outputs were practically identical - the 3 objects graphics state are setup once, followed by 500 glLoadMatrix and glCallList calls. 3 x (graphics setup, 500 x (matrix, calllist)) 3 graphics state changes The more complex app is completely different, the objects are drawn in arbitrary order with their graphics state updated every time. 3 x (500 x (graphics, matrix, calllist)) 1500 graphics state changes All apps call osgUtil::Optimizer::optimize on the scene. I'm digging through the complex app to see if there's a disable_rendering_optimizations call. Does anyone know what would cause this type of behavior? Thanks, Brian This is a PRIVATE message.

About VPB and osgEarth. I think so too. Nevertheless, they are both great tools! Thumbs up for the developers. The input data I currently have is a regular grid with holes. At the moment support for irregular meshes is not needed. All mesh manipulationa will be based on the regular grid. Do you have a hint how to efficiently triangulate this regular grid with holes? Since the resulting mesh will be pretty big and may not fit in the texture memory (I also have to share resources with a ravenous volume renderer), my first thought was using a continious LOD (no popping) approach. Does anybody have experience with such an algorithm? This algorithm may also be interesting for VPB. Ah, I almost forgot, the hole algorithm must be an out-of-core solution. So most propably I need to do paging at least between the main memory and the texture memory. Paging between hard disk and main memory may not be needed, since they normally have machines with quite a lot of memory. Thanks in advance for your comments.

Subject: [osg-users] Paging strategies for road tiles
Hi all,
My application involves road vehicles driving down long roads. Approx 1000
km of continuous road. The problem is that I can only hold about 100 km of
road before system memory runs out. Plan B then naturally falls on some
sort of paging strategy. I rewrote the software so it generates .ive files
containing about 10-30 km road. Then the plan was to use pagedLOD to page
in the files when needed.
My test program only uses four of these tiles, but I do not seem to get it
right. My pagedLOD nodes all lie under the scene graph root. Each one only
contains a reference to the corresponding .ive file and a range set from 0
to 2000 (since I don't want the next geometry to be paged in until I am
closer than 2000 meters). The center of each pagedLOD node is set to the
center point of the geometry in the file and the radius is set to half the
length of the road in the file.
But no geometry is ever paged in.
If I set the center to (0, 0, 0) the geometry will page in the first
segment of road, but then the geometry disappears when I traveled more than
2000 meters. The other tiles never shows up.
I am obviously missing something when setting up my pagedLOD. If someone
could give me a hint I would be most thankful.
Best Regards,
Björn

[osg-users] Offscreen Rendering - clamping problem
Folks, I'm doing offscreen rendering using fbos with attached images. I'm also using the postdrawcallback to do additional processing.

Re: [osg-users] RenderStage::draw order of copyTexture and PostDrawCallback
Hi JP, I'm using a 3rd party library to do filtering on the rendered image. They do all their magic using opengl in a function call from the postdrawcallback. Here's what it currently does: draw - FBO - copy to cpu - postdraw The postdraw operates on the FBO after it's been copied to the cpu and I never see it. Here's what I want to do: draw - FBO - postdraw - copy to cpu I want to access the image with the filtering effects included. Does this make it clearer?

Re: [osg-users] RenderStage::draw order of copyTexture and PostDrawCallback
Hi JP, I was trying to determine if the current order (copy image, then call postdraw) was deliberate for specific reasons, or if it just got coded that way. I understand where you would want the copied image to be available in the postdraw, but I also understand where you would want the postdraw to apply to the image before the copy. It just depends on what the intended purpose of the postdraw is. Personally I feel the postdraw should occur before the copy and that the copied image should be accessed on the cpu side during the update phase. Brian This is a PRIVATE message.

Re: [osg-users] RenderStage::draw order of copyTexture and PostDrawCallback
Hi JP, I think this is the common case and I always understood postdraw to mean that the camera is done with rendering/drawing. I've always thought of it as the last chance to draw something, essentially a hook into the drawing phase to integrate things that don't fit well in the scenegraph architecture. So, if you wanted to add things to be done before image copy, it should be part of the camera's subgraph. I guess I could do this. Create a custom drawable that call the 3rd party function. The difficulty will be guaranteeing it's the absolutely last thing drawn. The postdraw makes this easy. Brian This is a PRIVATE message.

Re: [osg-users] OSG and WPF Questions
Hi Martin, I replied to your message earlier, but I thought I would post my experience here for the benefits of those reading this thread down the line: What I did was create a WinForms Control that hosts the OSG window. Look for examples (theres a good one on CodeProject I think) of integrating WPF and OpenGL. OSG will be the same. This is necessary because WPF uses HWNDs only for the top-level window - everything below is DirectX. But a WinForms control has an HWND, and WPF has an interoperability feature where it can host WinForms controls. There are limitations however - principally that transparent WPF popup windows (used for messages, menus, etc) do not show up properly over the OSG window under XP on most NVIDIA graphics cards (non-Quadro cards), according to NVIDIA. One possible workaround would be to have OSG render to a texture and then blit that to a WPF canvas. I have been intending to do this - but have not gotten around to it yet. Currently I just structured my menus to avoid the overlap. I should also mention that it is useful to crank up the OSG render loop during the initialization of the control - not at construction, IIRC. There are a few other hurdles, like having to use the dispatcher to update WPF UI widgets, when the update originates from OSG - but these type of threading issues are to be expected in this type of app anyway. A lot of my daily pain comes from having to drill a piece of information down through several layers of code (abstraction layers for threading and for the managed/native transition) to get from the UI to the OSG render loop, which is again, to be expected. I have found a couple of issues with events, such as WPF not passing drag events (that originated from outside the app) down to OSG - which I dealt with by handling the events at the WinForms level, and then drilling down the mouse drag info to my OSG render loop.

Yes I did guess that I'm using the scene graph wrong. Fortunately with regard to our scene, while we have a lot of objects, the detail is not significant. The application allows users to simulate certain conditions that would occur in an industrial plant. So long as the model is a crude reflection of the plant it works, so we are already significantly optimising geometry. Rendering is only required as the user moves around the plant, or if an object is manipulated. During render we are currently hiding the smallest 50% of objects, which works remarkably well to improve usability (A full re-draw is performed when the user stops moving), but still the frame rate drops below interactive levels depending on how many objects remain. With regard to flattening of static transforms - how exactly would we do this? I was thinking to put a PAT as parent of a geode only while the user is picking/manipulating it, then remove it after, somehow matrix-multiplying the transform with vertices to get the new position. Is this possible? With regard to LOD's - sounds like a good plan but I think this may end up using more memory (which is an issue) even though it improves rendering performance. Paging does interest me though. I already set the cull settings to ENABLE_ALL_CULLING. I noticed that shadow occlusion (which I believe means when a large object occludes the camera, objects behind it are culled?) seems to have no effect. Is this due to my flat scene graph? View frustrum culling seems to have the largest effect. With regard to efficiently managing the scene graph (having a balanced tree), thanks for confirming that. I did have a hunch that would be the case but its nice to know. With regard to state sharing - is it possible to have one state object on multiple geodes? Or did you mean have multiple statesets with similar states?

[osg-users] Custom EventHandlers and Manipulator problem
Hi, I am using a combination of osg manipulators (fly, drive, etc.) with a KeySwitchManipulator. After these are set up, I have several tools which can be loaded at runtime, and each of them can register event handler callbacks for things like mouse up and mouse down. These handlers are working correctly, except the motion model manipulators furnished by osg are still getting the events, despite the fact that the handlers return true indicating the event was handled. So when you click and drag a building, for example, the view will rotate and spin in an undesirable fashion. I ran across a thread (http://forum.openscenegraph.org/viewtopic.php?t=2544highlight=return+manipulator) from back in May 2009 where Robert said: In OSG-1.x events were not passed on if handled. In OSG-2.x events are passed on to all manipulators/event handlers and it's the event handlers responsibility to decide whether they want to ignore handled events or not. This approach is more flexible and robust once you now about if (handled) trick. So what I am wondering is, what is the correct way to keep the built-in manipulators from responding to these handled events? I know about using the following code in custom maniuplators: Code: if (ea.getHandled()) return false; But what about with the built-in ones? And does the order in which the event handlers are registered affect anything? I am using OSG 2.6.1 with MS Visual Studio 2008 on Vista-64. Thank you!

[osg-users] MatrixManipulator::home(double) doesn't seem to work
Hi, I am trying to reset my viewer's position in response to an external UI event using the home(double) function on MatrixManipulator, but to no avail. The call to setHomePosition() is working correctly, as I can hit the spacebar, and it takes me to the proper location. The online page for MatrixManipulator does not say what the double parameter does, but a comment in the code says it is the current time. I tried passing in viewer-elapsedTime() and then I tried 0.0 - and neither seemed to work. On digging through the code, it appears that KeyswitchMatrixManipulator does not actually implement this function (at least in my version of OSG - 2.6.1). I then tried getting the current MatrixManipulator from it and calling home(double) directly on that - still with no effect. Am I doing something wrong? Is there a better way to set the view to a desired location and orientation? Is this a bug that's been fixed in a more recent version? Thank you!

Is that just building X apps with OSG as opposed to OSG being built as X. Even though you use a configuration heavy on X - it still build OSG as native Windows.

Re: [osg-users] Outline Effect traversal crash
Hi Maciej, Thank you for the example. It seems to be a lot faster than what I was doing earlier. Before when a node was selected, I removed it from its parent, created an osgFX::Scribe effect and placed it under the parent, and then reattached my node under that. But there was a slight delay between when the node disappeared, and when it reappeared selected. Because the nodes are buildings placed on geo-specific high-resolution imagery, this had the curious effect of make the building appear to be push into the terrain temporarily, and then spring back into position with the Scribe effect applied. Thanks for the links to the post and to the cel-shading article - those helped a lot! I did have one question about the new selection method you demonstrated. It makes the building appear to be all white, since the texture is turned off. Is this correct? I tried disabling that part of the code, but now the backfaced outlines are not enough to make the object stand out. What I would really like to do is outline the object in a striking color (say bright yellow, or something) and then render the textured object with a slight cast if the same color. Is this possible in OSG? I have searched though the archives, but without a lot of success yet. Just a pointer to some techniques that might work, or to a forum thread I missed would be a great help! Thank you!

Re: [osg-users] Outline Effect traversal crash
Hi Robert, Thanks for that clarification, as my understanding of where nodes should be added and removed was exactly backwards. I did paraphrase my code extensively, because there was a lot of unrelated code - but I guess I didn't include enough. I went to create a simpler example using osgcompositeviewer as a starting point, when I noticed that it is doing exactly the same thing that I am trying to, only in the handle() function of osgaGA::GUIEventHandler, which is called during the event traversal of frame(). When you said it's best to avoid modifying the scenegraph during a traversal, did that specifically mean the Update Traversal, when NodeCallbacks are called, and that modifications in event callbacks are OK?

Re: [osg-users] Outline Effect traversal crash
Hi, I switched my code around to where the model was being added from the main loop rather than the update traversal, and it was still crashing. On closer examination I noticed that the crashes were occurring during the render traversal, so I began to suspect the effect itself. When I replaced the effect with an instance of osgFX::Scribe, then everything worked correctly. So something was amiss in the Outline effect itself. I was using it only because I did not know about the Scribe effect, which is better for my purposes anyway. Thank you!

[osg-users] Outline Effect traversal crash
Hi,
I am trying to implement a mechanism by which selected objects in my scene are
highlighted. Searching the forum I found a reference to the Outline effect (an
implementation of osgFX::Effect) on Ulrich Hertlein's web site
(http://www.sandbox.de/osg/), and I have attempted to integrate it into our app
- however, most of the time, whenever the object which is outlined first comes
into view, the app crashes in osg::NodeCallback::traverse, because the
_nestedCallback member is corrupted. This is on Windows Vista-64, running OSG
2.6.1 built with Visual Studio 2008, in Debug mode. We are running OSG
multithreaded, and all my code setting up the effect is called from
osg::NodeCallback::operator() on the render thread. The general flow is as
follows:
Code:
osg::NodeCallback::operator()
{
osg::PositionAttitudeTransform* modelTransform; // local transform to
position the model in the world
osg::Node* someChild; // some model
osg::ref_ptrosgFX::Effect fxNode = new osgFX::Outline();
fxNode-addChild( someChild );
modelTransform-addChild( fxNode.get() );
}
Am I missing something obvious? If not, ideas or debugging strategies would
also be greatly appreciated!
Thank you!
Brian

Re: [osg-users] Dinamic Line Drawing
Allen,
Your code has the following line:
m_ogeomTrailGeometry-dirtyBound(); // forces redraw
dirtyBound does not force a redraw. It simply recalculates the bounding
volume for the geometry. The problem you were having before was that the
geometry was being clipped because the bounding volume was incorrect.
Your performance issues can be due to a number of things.
How many verts do you have?

Subject: Re: [osg-users] Dinamic Line Drawing
Thx everyone!! for the help. :D :D You've given me a lot to think about.
I really appreciate your time.
J-S, here's my code that now works but still drags a little after a few
thousand iterations. I found that setVertexArray is (I believe, but could
be totally wrong) actually copying the array I send it. After a few
thousand times of being called, it really slows down my entire interface.
In fact, my interface Almost crawls to a halt calling setVertexArray() each
time through the frame loop after about 4000 calls to it.
And I'm drawing a LOT of small line segments each millisecond to make up
the long looking line.
I'm not using vertex buffer objects... yet. if I need to switch to them, I
will. Though that will be in the land of experimentation for me too. ha,
ha,... :-)
I found that dirtyDisplayList() w.o dirtyBound() did nothing. I found that
dirtyBound() worked all by itself to get the line to draw during each
iteration of my osg::viewer::frame loop.
I'm using osg::PrimitiveSet::LINE_STRIP as my primitive type and I do not
need to push_back 2 vertices per line segment - I think. [Embarassed] At
least, my line is being drawn... :)
Honestly, I think it's the way I'm drawing the line. I don't believe there
is a bug in OSG. I'm just to new @ this stuff.. ha, ha...
here's my code: snippets of it: the 2 main methods w/in my class are 1)
setup my line and 2) then to add to that line one new vertex at a time.
This code actually works but it does 'slow' down after a few thousand
iterations and then speeds up.. and slows down and speeds up...

Re: [osg-users] Dinamic Line Drawing
You probably don't need to call setFirst(0) every time, but it won't hurt either. Also, when dynamically changing geometry this way you need to manage display lists (either disable them or dirty them when changed) and you need to manage the bounding volume (either dirty them on change or override the computeBound() method).

Re: [osg-users] SGI declares bankruptcy (UNCLASSIFIED)
So sad. I had the first Indigo that would digitize video back in '92, and later on I had an Onyx in my house for about a year. It did use a lot of electricity though... This certainly wasn't a surprise, but I will miss them. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=9683#9683 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Import Large Meshes
Folks, I'm trying to import large meshes, +10 million verts, +20 million tris from obj files. I'm not familiar with the terrain generation/processing parts of OSG and was wondering if there are any utilities that I can use to subdivide these or convert to pageable chunks.

Re: [osg-users] Most efficient way to use osg::DrawElementsUInt?
Jesper, I've encountered similar issues when managing 1000's of particle systems (bullet splashes in the water). The problem is the constant allocating/deallocation of memory when you create new primitive sets and then remove them. I ended up caching the primitive sets when the particle system ended and then reusing them. This along with using reserve() to preallocate the required number of elements, resize(0) to reset the element counter - without releasing the memory, and the primitive set setCount() method to adjust the number of prims being drawn each time the particle system was updated. This only works of the things you're creating all similar. It's comparable to what you're doing with the static memory - but within the osg framework. Brian This is a PRIVATE message.

FYI push_back() on an pre-reserved() vector/container should not be a performance issue. Under debug in visual studio, if you are storing anything other than a pointer, then a push_back etc will still incure a 'new and a copy' and this can get expensive if your doing a lot of them, under release this handled more efficiently Gordon Product Manager 3d __ Gordon Tomlinson Email : gtomlinson @ overwatch.textron.com __ -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Peter Hrenka Sent: Thursday, March 26, 2009 8:16 AM To: OpenSceneGraph Users Subject: Re: [osg-users] Most efficient way to use osg::DrawElementsUInt? Hi Jesper, Jesper D. Thomsen schrieb: Hi, and thank you. I naturally tried to use reserve() (but thanks for suggesting it) and this of course helped somewhat, but it still seems to be the primary bottleneck. I've changed most of the rest of the per-frame geometry generation code to use static arrays rather than std::vector and this caused a major speedup (factor 10 or more) of my own part of the code, but I'm still stuck with the push_backs on osg::DrawElementsUInt. Maybe there's just no faster way to do it, or maybe I'm just using OSG in a somewhat un-intended way. Jesper D. Thomsen Just some more ideas/comments: Are you testing a release build? Debug-Verions (especially on Windows) are known to have dramatically slower implementations. What profiling tool are you using? Sometimes the output is misleading and can point you in the wrong direction. As from my experience push_back() on an pre-reserved() vector should not be a performace issue. If you can spare the memory you could also try swap(), implementing your own double-buffering for your osg::DrawElements.

Hi Jesper, Jesper D. Thomsen schrieb: Hi all, I'm developing an application where I have to create up to 1000 osg:geometry objects per frame during certain interaction modes. I'm using osg::DrawElementsUInt push_back() to define the geometry primitive sets, and this push_back() seems to be the primary bottleneck for my applications graphical performance. Is there a more efficient way to define the primitive sets than to fill a osg::DrawElementsUInt by push_back and add it to the geometry? This is currently bringing me down to about 1 second per frame, which is kind of a roadblock. You can use reserve() to pre-allocate the needed memory. After that push_back() will not perform any reallocations/copies until the limit is reached. regards, Jesper D.

Re: [osg-users] NightVision (Green and Blurry?)
To do this even minimally, will require using shaders and multi-pass rendering. If you're not experienced with these you should go through the osg examples and get comfortable with these techniques. Also, osgppu is a good way to quickly get started (it hides a lot of the details). Then you can try different ways to add noise, convolutions, haloing, and experiment to get the results you want.
