Re: [osg-users] re-initialize OpenGL objects after window
Hi Terry, I'm not clear on the sequence of events in your app, but it does look like you are probably doing a couple of things that shouldn't be required. First up, it is possible to release all the GL objects in the scenegraph, flush the deleted GL objects, delete a graphics context, and then reuse the same ContextID for a new graphics context, as all the slots for this contextID shoudl be cleared already. I've tested this sequence out with using osgViewer and it works fine. One thing to be wary of is that that you have to do the osg::flushAllGLObjects(contextID) from the graphics thread of the graphics context that you are about to delete as it does all the glDelete's of the various OpenGL object ID's. If your graphics context has already been deleted then you'll need to call osg::discardAllDeletedGLObjects(contextID) which will clear out all the internal buffers storing the deleted OpenGL object id's without attempt to do any GL calls. Note, the osgUtil::SceneView calls just call the osg::flush/discard.. methods. If these internal OpenGL object buffers aren't empty when you create your new graphics context then you'll find the OSG will try to reuse those OpenGL objects believing them to still be relevant - and this will cause a range of problems from crashes to missing textures. Incrementing the ContextID for each new context will work around this reuse as it'll force the OSG to create a new set of buffer entries for the new context, but if you manage things correctly it won't be necessary. osgViewer will actually do a lot of this work for you, so I'd recommend using it instead of digging down into the low level SceneView.

I played around with rebuilding my OpenGL objects some more and found that the necessary steps are: sceneview-releaseAllGLObjects(); state-setContextID(state-getContextID() + 1); For completness's sake, I've been doing this scenegraphroot-releaseGLObjects(); sceneview-releaseAllGLObjects(); sceneview-flushAllDeletedGLObjects(); state-setContextID(state-getContextID() + 1); However, the extra two steps don't appear to be necessary. If I only increment the context ID and do nothing else, most OpenGL objects get rebuilt except for the ones that were onscreen at the time of the context switch. This makes it look as if all objects not culled on the last frame do not get re-initialized. So while I have a working solution, it might be fragile since I still don't completely understand what's going on inside OSG.

The scene graph itself doesn't know about the fact that you've changed the graphics context from underneath it so you'll need to tell it but doing a scenegraph-releaseGLObjects(); The SceneView methods just clean up already released GL objects, so you'd call these after the scenegraph release.

Re: [osg-users] Double transparency :O
Hi Rene,
To do transparency work you'll need to enable OpenGL blending via:
stateset-setMode(GL_BLEND, osg::StateAttribute::ON);
And is typically best also tell the OSG to depth sort the geometry too
by placing it in the transparent bin:
stateset-setRenderingHint(osg::StateSet::TRANSPARENT_BIN);

For a lighting event here in Eindhoven (NL) our company is going to project
an image on a building using big ass beamers. It's an event which follows up
after Glow (http://www.gloweindhoven.nl/). Our idea was to have an
interactive application running between two users and the image projected by
the big ass beamer. We're going to capture the movements of two users that
are throwing paint at a building. All the user does is make the gesture,
and my application extrapolates the course the paint will fly at the
building. To round it off; a nice animated splash of paint is then projected
on the building.
So I decided OSG would be a decent way to make this happen. Well... I got
most things in place. Someone supplied a sequence of transparent PNG images
for me to display. I used libpng to load them and put them in a osg::Image
object which I then proceed to put in an osg::ImageSequence object. I then
proceed to do some things I read on these forums to make the loaded PNG
appear as a transparent texture-on-a-quad in my view.
And this actually works:
Code:
SplashContainer
LichtStadEindhovenApp::Splash(
osg::Vec3f position,
osg::Vec2f scale,
DWORD color,
float speed,
int nsplash)
{
SplashContainer cont;
osg::ref_ptrosg::ImageSequence tmpImageSequence = new
osg::ImageSequence();
for ( int k = 0 ; k splash[nsplash]-size() ; k += 1 )
{
tmpImageSequence-addImage(LoadBitmapPNG(splash[nsplash]-operator
[](k).c_str(), color));
}
osg::ref_ptrosg::Geode geode = new osg::Geode();
osg::ref_ptrosg::PositionAttitudeTransform texPAT = new
osg::PositionAttitudeTransform();
osg::ref_ptrosg::Geometry quad1 = createTexturedQuadGeometry(
osg::Vec3d(0.0, 0.0, 0.0), //Center vector
osg::Vec3d(0.0, 0.0, scale.x()), //Width vector
osg::Vec3d(scale.y(), 0.0, 0.0), //Height vector
1.0,
//Texture coordinates left
1.0);
//Texture coordinatse top
texPAT-setPosition(position);
mNavTrans-addChild(texPAT.get());
texPAT-addChild(geode);
osg::Quat q(osg::DegreesToRadians(90.0f), osg::Vec3f(0.0f, 1.0f,
0.0f));
texPAT-setAttitude(q);
geode-addDrawable(quad1.get());
osg::ref_ptrosg::Texture2D splashTexture = new
osg::Texture2D(tmpImageSequence);
osg::ref_ptrosg::StateSet stateset = quad1-getOrCreateStateSet();
stateset-setTextureAttributeAndModes(0, splashTexture.get(),
osg::StateAttribute::ON);
stateset-setMode(GL_LIGHTING, osg::StateAttribute::OFF);

osg::BlendFunc::ONE_MINUS_SRC_ALPHA);
stateset-setAttributeAndModes(texture_blending_function.get(),

osg::ref_ptrosg::AlphaFunc alpha_transparency_function = new

alpha_transparency_function-setFunction(osg::AlphaFunc::ComparisonFunction::ALWAYS,
0.5);
stateset-setAttributeAndModes(alpha_transparency_function.get(),

stateset-setRenderingHint(osg::StateSet::TRANSPARENT_BIN);
quad1-setStateSet(stateset.get());
cont.geode = geode;
cont.imgseq = tmpImageSequence;
cont.pos = texPAT;
cont.f_incr = speed;
cont.f_time = 0.0f;
if ( nsplash == 1 || nsplash == 2 )
cont.bSaveLastFrame = false;
else
cont.bSaveLastFrame = true;
printf(ptr count 1: %d\n, tmpImageSequence-referenceCount());
m_vecSplashes.push_back(cont);
printf(ptr count 2: %d\n,
m_vecSplashes[m_vecSplashes.size()-1].imgseq-referenceCount());
nThrown += 1;
return cont;
}
My problem is is that I also want this quad to be 70% transparent. So that
when a new quad is placed in front of it, a little bit of the image farther
away remains visible.
I've read several posts all of which say I should add this piece of code

Re: [osg-users] Question about possible changes between 2.6 and 2.8.2
Hi Peter, For most users moving from 2.6 to 2.8.2 should simply be a case of rebuilding the OSG and your app, typically no code or link changes should be required. It looks to me link your app isn't linking to the core OSG library for some reason, so go check what you app is linking against and make sure all the correct libs are in the right places w.r.t project files.

Re: [osg-users] Double transparency :O
Hi,
instead of attaching a material, just check what colours the
createTexturedQuadGeometry assigns to the quad. I think if you modify
the alpha there it should work. OSG by default uses GL_MODULATE to get
the final colour from the quad colours and the texture colours. Make
sure blending is on for all the transparent geometry you draw (quad and
whatever you are drawing over it later).

[osg-users] Rotating models with respect to CoordinateSystemNode / EllipsoidModel
Hi,
I have a moving model located in a CoordinateSystemNode with a default
EllipsoidModel. The goal is that the model is rotated into the direction which
it is moving. My current code looks like this:
Code:
osg::Matrixd ModelPositionCallback::calculatePositionMatrix(
const osg::EllipsoidModel* ellipsoid,
const osg::Vec3d newPosition,
const osg::Vec3d oldPosition)
{
osg::Vec3d up = ellipsoid-computeLocalUpVector(newPosition.x(),
newPosition.y(), newPosition.z());
osg::Vec3d forward = newPosition - oldPosition;
forward.normalize();
osg::Quat rotation;
rotation.makeRotate(up, forward);
osg::Matrixd matrix;
matrix.makeTranslate(newPosition);
matrix.preMultRotate(rotation);
return matrix;
}
The problem is, that the rotation obviously depends on the model's position
within the CoordinateSystemNode / EllipsoidModel, hence the model doesn't head
in the right direction right now. It is probably pretty simple to do -- but
I've searched the forum and googled for this but I still have no clue on how to
solve this... any ideas?
Thank you!
Cheers,
Michael

[osg-users] osgAnimation::ReaderWriter Bug on Linux ?
We noticed a Bug in osgAnimation of the stable osg release 2.8.2, and
only on Linux ( Ubuntu 9.04 ), which does not occur on Windows with
Visual Studio 2005.
When writing out an osgAnimation programm to a osg file, the process
stops before writing keyframe data:
Node {
nodeMask 0x
cullingActive TRUE
UpdateCallbacks {
osgAnimation::BasicAnimationManager {
num_animations 1
osgAnimation::Animation {
name myTestanimation
num_channels 1
Channel {
name position
target whatever
Keyframes Vec3 2 {
In Debug Mode we figured out, that the problem comes from
src/osgplugins/osganimation/ReaderWriter.cpp Line 273, 274, pointer kk
points to adresse 0x0 after dynamic_cast
osgAnimation::Vec3KeyframeContainer* kk =
dynamic_castosgAnimation::Vec3KeyframeContainer*(kf);
fw.indent() key (*kk)[k].getTime()
(*kk)[k].getValue() std::endl;

Re: [osg-users] Improving multisampled FBO
Hi Paul, I hope Robert also reads this ;-) I compiled your code. Everything seems fine. I agree that setImplicitBuffers() or even setImplicitBufferAttachments() would be more self explanatory. I would also like to have one more (global) level of control where I would be able to set defaults for _renderBuffersMask _resolveBuffersMask for all cameras. I guess Robert saw a need for this as well, when he proposed to extend DisplaySettings for this purpose. It could be useful for already existing code like osgShadow shadow map techniques. By zeroing _RenderBuffersMask we could make these techniques more efficient, as most of the shadow map cameras does not need to use COLOR_ATTACHMENTS. Extrapolating Robert sugesstion (I am trying to guess how he would tackle this) I would add _implicitBufferAttachmentsRenderMask _implicitBufferAttchmentsResolveMask flags and corresponding setters and getters to DisplaySettings structure. I would also initilize them to defaults you had set up for the camera in your submission: ie USE_COLOR_BUFFER | USE_DEPTH_BUFFER. In the Camera class I would add one more enum value USE_DISPLAY_SETTINGS_MASK and would make it a default for the Camera. This flag would mean that Camera honors flags set in associted DisplaySettings. So it would be possible to setup defaults for all cameras by simply changing masks in DisplaySettings instance. And it would be easy to override global defaults with the flags and methods you added when creating a camera. Would this work for you ? I will prepare and submit a code with these modifications if you accept general direction.

[osg-users] Side-effect with two cameras sharing Viewports
Hi, i noticed a strange (buggy?) behavior with two cameras sharing the same Viewport instance with version 2.9.5 (Windows XP). Situation: Main camera, adding a slave camera (with addSlave) and setting the slave camera's viewport with this line of code: slaveCamera-setViewport( viewer.getCamera()-getViewport()); The objective is to have two cameras rendering to the whole window Problem: If the viewer is in window mode (setUpViewInWindow) and the window is resized, the viewport updates incorrectly. In my case, it doesn't fill the window. I suspect this behaviour is due to GraphicsContext::resizedImplementation having updated the viewport twice, since it is share between the two cameras. Workaround: Don't share the viewport between two cameras :) slaveCamera-setViewport(new osg::Viewport(*(viewer.getCamera()-getViewport(; or osg::Viewport* vp = viewer.getCamera()-getViewport(); slaveCamera-setViewport(vp-x(), vp-y(), vp-width(), vp-height()); If this use isn't as expected (i use it wrong) or if resizedImplementation need to be fixed, then i could try do the job and submit a patch for this odd behaviour. At least i could modify Camera and add some comments regarding this behavior. But first i wanted to know experts advise about it.

{
_oldManipulator = _view-getCameraManipulator();
_view-setCameraManipulator(_animPathManipulator.get());
_currentlyPlaying = true;
}
}
// The user has requested to STOP playback.
else
{
// Restore the old manipulator if necessary and stop playback.
_view-setCameraManipulator(_oldManipulator);
_currentlyPlaying = false;
_oldManipulator = 0;
}
}
I guess, i am doing something wrong. Please give me some support.

Re: [osg-users] Side-effect with two cameras sharing Viewports
Hi Himar, The assumption that I made with osg::Camera is that each camera would have it's own Viewport, sharing a Viewport between Camera's is not something I've considered so code like the GraphicsContext code for passing up updates to resizing of the window will probably be resizing the viewport onces for each Camera. Solutions would be to clone the viewport for your slave camera, or modify the resize code so it doesn't resize viewports that it's already resized. The later is really the best solution as it would remove the assumption of one Viewport per Camera. I'm currently got my head down on OpenGL ES work so if you could dive into the appropriate code and provide a solution it'd appreciated :-) Cheers, Robert.

Re: [osg-users] Improving multisampled FBO
Hi Paul,
Thanks. I am almost done with modifications for DisplaySettings. I have to test
it and will submit the code tomorrow. But I have one question regarding your
changes in RenderStage.cpp. I have understood that RenderMask defines implicit
attachments for main FBO and ResolveMask defines implicit attachments for
multisample FBO. I noticed that when multisampling is not used both masks are
actually set to RenderMask value (RenderStage.cpp line 352). But when
multisampling is on, it looks like masks are swapped because ResolveMask is
used to force implicit buffers for main FBO and RenderMask is used to force
implicit buffers for MS FBO. Its bit surprising to me, but maybe its correct ?
For example: see excerpt from RenderStage lines 440-455
if (!depthAttached)
{
if( resolveBuffersMask osg::Camera::USE_DEPTH_BUFFER )
{
fbo-setAttachment(osg::Camera::DEPTH_BUFFER,
osg::FrameBufferAttachment(new osg::RenderBuffer(width, height,
GL_DEPTH_COMPONENT24)));
depthAttached = true;
}
if (fbo_multisample.valid()
( renderBuffersMask osg::Camera::USE_DEPTH_BUFFER ) )
{
fbo_multisample-setAttachment(osg::Camera::DEPTH_BUFFER,
osg::FrameBufferAttachment(new osg::RenderBuffer(width, height,
GL_DEPTH_COMPONENT24, samples, colorSamples)));
depthAttached = true;
}
}
Cheers,
Wojtek Lewandowski

[osg-users] Mac OS X mouse handling Warp pointer.
Hi, I'm having an issue which with warping the mouse pointer on Mac OS X that is generally expected, but behaves differently than on other platforms. That is, when you warp the mouse pointer using either of the warp functions (GraphicsWindowCarbon uses CGDisplayMoveCursorToPoint), all input is frozen for 0.25 seconds. When trying to implement a mouse look style mouse movement, the normal method is to move the mouse pointer back to the center of the screen even frame on other platforms, but doing this blocks all input in OS X for a quarter second unless I call CGSetLocalEventsSuppressionInterval(0); The other method is to disassociate the mouse pointer position from the mouse movement, but that solution won't work with the current osx window classes because they track the mouse position, not its movement. I was going to submit a change adding the above line to GraphicsWindowCarbon, and possible the Cocoa version, but it appears that this function is deprecated in 10.6 in favor of CGEventSourceSetLocalEventsSuppressionInterval(...); So, to conclude, I have two points to this post. 1. I think we should make this the default behavior so it will work the same across platforms, unless there is another solution 2. I don't know how to implement this using the other function because I'm not an expert on event sources, and I haven't really been able to make it work. Does anyone more skilled than I in this area know how to make this work or do you recommend I just use the older function for now? Thank you!

Re: [osg-users] layering of text and geometry in a 2.5D setup
Thanks Paul, Jeremy, So after some contemplation I am pretty sure I want to use the painter's layering.

If I understand correctly there are two default bins--RenderBin and DepthSortedBin. Former is sorted based on the binNum, latter based on the depth. I guess what I don't understand is how does the binNum realate to the other items in the default bin. I know they are rendered in the order they are added to the scene.

[osg-users] Help with Run-Time error using osgdem
All, I'm currently receiving a Windows Run-Time Error when running osgdem.exe in an attempt to build a pretty large database (approx. 132GB or so). I have a process that generates 1879 bitmaps of various resolutions (up to 2 meters per pixel) and stores a bunch of data for each bitmap in a text file which I then pass into osgdem.exe using the -ARGS_FILE option. Some of the data contained in the file for each bitmap is the lower-left-hand coordinate of the file (as --xt and --yt), the size in meters per pixel (as --xx and --yy), and the path to the filename (as -t). I've done this before successfully with smaller samples of the visual database I'm generating, but now I'm using the entire DB and at a minimum of 4 meters per pixel. Are there any suggestions as to why I might be getting a run-time error here? Any help is appreciated! Thanks, Jake _ Windows 7: Simplify your PC.

Re: [osg-users] Improving multisampled FBO
Yes it's quite confusing.
The RenderStage code was already set up as follows: If doing MSFBO (and
therefore need two FBOs, one for multisampled rendering and one for
final resolve), then configure fbo as the resolve FBO, and When done
configuring, swap it into _resolveFbo (see line 554). But, if not
using MSFBO, then fbo is just the render fbo.
(I did not write this code, I am just the poor sap left to maintain it. :-)
My code handles this correctly: If using MSFBO, then resolveBuffersMask
is the value set by the app for the resolve buffers. But if not using
MSFBO, then resolveBuffersMask is the value set by the app for render
buffers. In both cases, resolveBuffersMask is used to configure fbo.
So, my code is correct, in light of how the existing code is written.
I attempted to explain this briefly in code comments at lines 349-351
and also lines 377-378, but perhaps to clarify things further, you could
paste this email from me as a code comment about line 442.

Re: [osg-users] osgslice Error Message
Hi, The osgslice example fails on windows vista on revision 10691. GraphicsContext::setWindowingSystemInterface is never called because the static object RegisterWindowingSystemInterfaceProxy createWindowingSystemInterfaceProxy in GraphicsWindowWin32.cpp is never instantiated. Even if not using the viewer, the example is supposed to link with osgViewerd.lib, but it seems the global object is just wiped out for a reason I can't explain... Creating a dummy viewer at the end of the main function force the instantiation of the global object and lets the example run. Tested in debug on Visual Studio 2005. This really looks like a compiler issue... regards, Vincent Gadoury -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=18743#18743 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] layering of text and geometry in a 2.5D setup
How does this look like ...
Code:
PositionAttitudeTransform {
UniqueID PositionAttitudeTransform_15
nodeMask 0x
cullingActive TRUE
StateSet {
UniqueID StateSet_16
rendering_hint DEFAULT_BIN
renderBinMode INHERIT
GL_LIGHTING OFF
GL_DEPTH_TEST OFF
}
referenceFrame RELATIVE
position 0 0 0
attitude 0 0 0 1
scale 1 1 1
pivotPoint 0 0 0
num_children 1
Geode {
UniqueID Geode_17
UserData {
NodeCallback {
name MyTextfield
}
}
nodeMask 0x
cullingActive TRUE
StateSet {
UniqueID StateSet_18
rendering_hint DEFAULT_BIN
renderBinMode OVERRIDE
binNumber 1
binName RenderBin
}
num_drawables 1
}
}
The one drawable is the osgText. I am also :O new to writing osg files ...
couldn't get it to write the drawable to file.
(Paul, I am still working on the minimal example)
Thank you!
Cheers,

Re: [osg-users] Help with Run-Time error using osgdem
Hi Jake, For large databases you will have to use vpbmaster to manage a complete database build, osdem doesn't scale on it's own. Robert.

I have a process that generates 1879 bitmaps of various resolutions (up to 2 meters per pixel) and stores a bunch of data for each bitmap in a text file which I then pass into osgdem.exe using the -ARGS_FILE option. Some of the data contained in the file for each bitmap is the lower-left-hand coordinate of the file (as --xt and --yt), the size in meters per pixel (as --xx and --yy), and the path to the filename (as -t). I've done this before successfully with smaller samples of the visual database I'm generating, but now I'm using the entire DB and at a minimum of 4 meters per pixel. Are there any suggestions as to why I might be getting a run-time error here? Any help is appreciated! Thanks, Jake Windows 7: Simplify your PC.

I would put the StateSet with the override flag all the way at the topmost Group in your UI, above all the Text and above all the other geometry you're drawing with the text. The one drawable is the osgText. I am also :O new to writing osg files ... couldn't get it to write the drawable to file. You don't need to do anything special to get the Drawable output. The fact that you are not getting the Drawable output would indicate that OSG can't find the .osg plugin for osgText. Perhaps you have a bad install.

Re: [osg-users] runtime bug when loading obj model in OpenSceneGraph 2.8.2
Hi, So I have read about .mtl and .obj files and understood what you meant. I created a program to optimize the model (http://cs.uiowa.edu/~tinguyen/OptimizeMtlFiles.rar) But the new one that I created doesn't look the same as the old one when I don't use texture. Please click this link to download both versions, and use osgviewer.exe to view them. http://cs.uiowa.edu/~tinguyen/supermarket_3ds.rar The old one has some color (again, without texture), but the new one doesn't. So I'm wondering what's wrong. Could any of you give me a hand? Thanks, Dat On Mon, Oct 26, 2009 at 10:10 AM, Nguyen Tien Dat tienda...@gmail.com wrote: Dear Ulrich, Sorry for my stupidity, but I don't know anything about modifying models. The model is actually created in VRML, and I use 3DS Max to export it to obj format. So if you can, please tell me a bit more about how to optimize the model: - How can you remove duplicate materials (if you can tell me how to do it by hand, that helps too) - What else can I do to load the model in an efficient way?

Can I specify it while using osgviewer.exe or I have to rebuild osgviewer.exe with the option? Unfortunately you can't (at the moment) set this option externally or internally, because the .obj loader doesn't pass the options object along. Even if you could it would only avoid loading the same image over and over again. It will not solve the massively duplicated state/material that the model has. Either the modelling is done very inefficiently in the 3D application or whatever exporter is used messes things up. If you absolutely have to use osgviewer (rather than your own app) I'd actually write a script to optimise the .obj and .mtl files by removing duplicate materials. What you might also want to do is to remove the 'map_Ka' (ambient texture map) statements since they are not used with the standard OpenGL paths (but are still loaded).

I think it's a runtime bug and would like to know how to fix it. Please find some pictures Not really a bug, I'd say you're running out of memory. - try to reduce the image sizes. - a lot of materials reference the same image. I don't think the obj loader caches this which means you're loading that image over and over again. Use osgDB::Options to specify caching of images. Oh, and you seem to have pretty much one material per drawable. This will absolutely kill your performance. Have a look at the .mtl file, you'll notice that there are heaps of materials that have identical properties. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Dat Tien Nguyen PhD student, Computer Science Department The University of Iowa, IA 52242 http://cs.uiowa.edu/~tinguyen ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
