Re: [osg-users] Trying to make Qt HUD inside OSG scene
Hi, Robert, Alistair Thanks for your replies. I've seen osghud example, but that one has no clickable elements on the HUD camera. I've tried looking into osgpick example aswell, as it looks more suitable for my needs (with clickable buttons), but the thing is I have to use InteractiveImageHandler for Qt elements so it didnt work. I've looked into Cookbook examples aswell, though maybe not deep enough. But anyway, changing new osgViewer::InteractiveImageHandler(widgetImage.get(), texture, camera); for new osgViewer::InteractiveImageHandler(widgetImage.get()); makes camera completely transparent: it does let me spin my 3d model through it but the button becomes unclickable too. Is it even possible to make e.g Qt button clickable while letting mouse controls through camera, like in osgpick? Am I missing something important? PS Right now I'm making new small camera for each Qt control (e.g I need button with 100px width and 50px height so there is fit camera created with a bit bigger size). Though I'm not sure if it's right way.

Re: [osg-users] Resetting OSG state when managing own context
Yup, well it's certainly possible (the shared context). It's what I'm doing now. I'm going to investigate the use of deleteAllGLObjects when I get back to the office and have a 2nd screen connected that I can test with (I'm using the scenario of moving a window between two screens to force a CAOpenGLLayer context refresh). If that works, it's likely I'll stay with the shared context single threaded approach. -- Neil -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=49605#49605 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] [3rdparty] osgWidget and rotation
Hi, I want to use an osgWidget to draw a compass. So, I need to use the rotation. The problem is that the origin of the osgWidget is at the bottom left and not at the center of the widget. How can I specify the center of my widget (since set Origin only move the widget) in order to have a good rotation.

Re: [osg-users] Trouble with LightSpacePerspectiveShadowMap artifacts.
Hi, Dario, LispSM is setup by default to cast shadows using light space backfacing polygons. That approach works well if models are closed and build with face culling in mind. If your model does not utilize cull faces (and your truck looks like that case), all front polygons will cast shadows. So the artifact you see is false self shadowing on front polygons. To work around that you will have to switch the sign of polygon offset factors and maybe further tweak polygon offset factors magnitude if your field of view gets big. You will find current polygon offset values in StandardShadowMap setup code. There is a method to set new polygon offset for the technique. PS: I highly recommend reading some papers on principles of ShadowMaping. There is a Mark Kilkgard presentation on the web that explains many of the problems. Cheers, Wojtek Lewandowski 2012/8/28 Dario Minieri para...@cheapnet.it Hi! Nice to hear for the new your technique, I will try today checking the svn. Is a ShadowMap tech, so the shaders are the same of StandardShadowMap.cpp file? Meantime, I attach a debug shadow snapshot with CAST and NOCAST setted on terrain. I'm not sure to understand well the result...the artifacts are the same in both cases, but the depth calculation seems to be different to me...You can see some specific stuffs? Thanks again for your suggestions.

Or... just try the ViewDependentShadowMap technique that now is available in svn/trunk. This new technique is more robust than LispSM and offers similar functionality w.r.t projections. It may or may not solve your problem, but as I'm the author of this particular technique I have a better chance of understand and helping address the issues.

Re: [osg-users] how to do culling with shader tranformed geometry?
Hellor Robert, Every day I try to think a bit less, but it does not work for me... ;) But seriously: OSG is a framework, which tries to fit several different use cases. And it is natural, that it will not fit perfect for every possible job. Thus I want to figure out, how I can use it in the best way for my purpose. I try to use shaders to project flat world geometry on a sphere to keep the scene graph simple. But cannot tune the culling stage to fit this situation (yet) and have to deal with a pretty crude workaround distorting the bounding boxes, which breaks the idea of keeping the flat world scene graph simple. I highly appreciate your help, but that does not imply, that I shall not have an own vision, of how to do certain things. Therefore I still think (being clever), that adapting the culling visitor would be a cleaner way. But unfortunately don't know, how to do it now, and since the OSG API is nearly undocumented, it is a hard way to go. All I want is a custom flat-world culler, set up of four clipping planes and a fitting AND/OR conjunction (for full-inside or warp-on-border cases). Is this that hard to do with OSG?

Re: [osg-users] how to do culling with shader tranformed geometry?
Hello Sebastian, unfortunately I cannot create bigger sets with more GL geometry in them, cause I need the geometry to be addressable. :( Sebastian Messerschmidt wrote: Hello Alexej, Robert I think the reason for Alexej to think that disabling the culling would improve render time in any way, is that he measuring the time of the cull traversal. Indeed the cull traversal time is culling + preparing the drawing of the geometries. I've fallen for this in the beginning. So maybe the problem lies with the number of drawables (i.e. there are too many too small batches). So being clever at this point would rather mean to make bigger yet fewer sets. cheers Sebastian -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=49620#49620 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Error while loading OSG model on Android
Hi, I build OSGAndroid example on Ubuntu device. I loaded and displayed OSG model successfully on my mobile device. Now I used the OSG lib in my project which are using some other libs. I made changes to Android.mk and Application.mk and compiled successfully. But to load model I gave static path to readNodeFile as /mnt/sdcard/OSG/lz.osg. When I run as Android Application I got Model not loaded message on cat log. If I give the same static path in OSGAndroid example then it is working. I am using Android 2.2 and OpenGl1.1 versions. Do i need to add any other things to my project. Can you please help me why the model is not loading? ... Thank you!

I can try to tweak these values in some way. You speaks about two stuffs which I would to discuss: 1. You say that the model must be closed, but what do you means precisely? Closed in term of vertex mesh or closed in terms of shape? For example a cube is a closed model, my truck obviously not... 2.

Re: [osg-users] a bug or feature in the osgb writer?
Hi John,
Oh, so you are talking about the saving/reading of geometry shaders,
not just geometries. :-)
After checking the osg::Program serializer, I can confirm this is a
bug. As GL_POINTS is defined as 0, the serializer will ignore it as
incorrectly recognize it as GL_NONE. And when you load the file again,
the Program class will use a default value for GeometryInputType, that
is, GL_TRIANGLES.
I'll submit the patch to osg-submissions at once. You can also modify
the line at src/osgWrappers/serializers/osg/Program.cpp:
#define PROGRAM_PARAMETER_FUNC( PROP, NAME ) \
static bool check##PROP(const osg::Program attr) \
{ return attr.getParameter(NAME)!=GL_NONE; } \
to
#define PROGRAM_PARAMETER_FUNC( PROP, NAME ) \
static bool check##PROP(const osg::Program attr) \
{ return true; } \
and see if it can work.
Thanks,
Wang Rui

Hi,
I apologize for the delay in responding.
Here's my attempt to provide a simple example. I am attaching the three
referenced files.
I run my program and dump the node in question into two files: dump.osgt and
dump.osg.
If I grep for Geometry in the two files I see:
dump.osgt:553: GeometryVerticesOut GL_GEOMETRY_VERTICES_OUT_EXT
4 dump.osgt:554: GeometryOutputType GL_GEOMETRY_OUTPUT_TYPE_EXT
5 dump.osgt:696:osg::Geometry {
dump.osg:49:GeometryVerticesOut 4
dump.osg:50:GeometryInputType POINTS
dump.osg:51:GeometryOutputType TRIANGLE_STRIP
dump.osg:661: Geometry {
That is, the osgt file seems to be missing the line
GeometryInputType GL_GEOMETRY_INPUT_TYPE_EXT 0
If I convert dumop.osgt file to an osg file and diff it with the original
osg
file I see:
diff dumpFromOsgt.osg dump.osg
46c50
GeometryInputType TRIANGLES
---
GeometryInputType POINTS
I think the problem is just in the writer, not the reader, because if I
manually add the missing line to the osgt file it works. And, it if convert
the modified osgt file to an osg file the input type is now points, not
triangles.
I seem to get the same results for osgb as I do for osgt.
I'm not sure how to answer the question about setVertexArray versus
setVertexAttribArray. But points.osg is the point data that's loaded.
I hope this helps. Please let me know if you need anything else that might
help with solving the problem.
Thanks,
John

I've done some testing and you aren't really doing anything wrong here;
it is simply a weakness in osgWidget I never thought of. I'm not sure
how to best proceed, but you have at least two reasonable options:
1) An osgWidget::Window is a MatrixTransform, and an osgWidget::Widget
is just an osg::Geometry. You could attach an
osg::Drawable::UpdateCallback to your widget, but you'd need to do some
fancy calculations to get it to rotate in place. I tried quickly doing
this, but couldn't get the math right in the few minutes I had to test
it... I've attached this code, but you'll need to fix it to make it
work.
2) Create one Window for your compass outline and another for your
compass spinner; add the spinner to the outline and call setRotate() on
the spinner window as needed.
In the long run, osgWidget should be rewritten to be more modern and use
my (and utilizing feedback from the community) improved understanding of
OSG in general. Alas, the bills don't stop coming, and the little free
time I have (I do Linux development as my 40+/week) goes to the
occasional contract I can secure or other such activities.
I would really like to go back and fix all the things I know are wrong,
I just need a solid, uninterrupted 2 weeks to do so. :)
Thanks !

[osg-users] [vpb] Speed of first frame rendering
Hi, I am a user of osgDEM and used this to generate a terrain database. When the terrain data is first loaded by osgViewer, there would be an initial load time. I am trying to reduce this load time drastically. I prepared two sets of terrain database for comparison of the initial load time. The first set has a flat terrain (i.e. all vertices have height z = 0) and the second set has uneven terrain (i.e. different vertices have different heights). Both database uses the same texture and have been compiled with osgDEM with the same parameters, with the exception the second set was provided with a DEM map. What I have found out is that the first set initial load time is much faster (more than 10x) than the second set. Why is this so, even the size of the textures and the number of vertices remain the same for the 2 sets? Thank you!

A Drawable can have a special ComputeBoundsCallback() (something like

Here is the code I came up with after your suggestion that does resolve

[code]

);
META_Object (anonymous, keep_bounding_sphere_t);
/* * * osg::Node * * */
virtual osg::BoundingSphere
computeBound (const osg::Node node) const;
private:
/// The axes that might be scaled and should be checked.
/// e.g. osg::Z_AXIS to check only the z-axis.
osg::Vec3 axes_;
};
keep_bounding_sphere_t::keep_bounding_sphere_t ()

{
}
keep_bounding_sphere_t::keep_bounding_sphere_t (const osg::Vec3 axes)
: ComputeBoundingSphereCallback (),
axes_ (axes)
{
}
keep_bounding_sphere_t::keep_bounding_sphere_t (
const keep_bounding_sphere_t other, const osg::CopyOp copyop )

axes_ (other.axes_)
{
}
osg::BoundingSphere
keep_bounding_sphere_t::computeBound (const osg::Node node) const
{
osg::BoundingSphere out = node.computeBound ();
const osg::PositionAttitudeTransform *pat =
dynamic_cast const osg::PositionAttitudeTransform * (node);
if (!pat)
return out;
osg::Vec3d scale = pat-getScale ();
double sscale = 1.0;
if (axes_.x ())
sscale = scale.x ();
if (axes_.y () scale.y () sscale)
sscale = scale.y ();
if (axes_.z () scale.z () sscale)
sscale = scale.z ();
if (sscale)
out.set (out.center () , out.radius () / sscale);
return out;
}
[/code]
My understanding of Transform::computeBound() could be better, but in my
case, it was effectively multiplying the bounding sphere radius by the
scaling factor even though the scaling factor only applied to a single
axis and should not have been a factor when calculating the boundary sphere.
Thus, the code above works provided the extent of the geometry along the
axis being scaled will never be larger than the extent of the geometry
along the other axes. I can think of a few improvements to this code
(like compute the bounds of the child node(s) directly then determine
what to do with the scale values). However, does this seem like a
proper/common approach to solving this problem? Another approach might
be to override the PositionAttitudeTransform node directly?

Judson

Re: [osg-users] [vpb] Speed of first frame rendering
Hi Boon Wah, Have a look at the on screen stats between the two datasets, there will be a difference, in particular with the number of vertices per tiles, and perhaps even the number of tiles as osgdem has a default limit of tile 64x64 for height fields and 256x256 for texels so when you introduce the DEM's it may be the DEM's that limits the number of tiles. In general one wouldn't expect the initial load time to be high on any paged database, normally it's very fast indeed and not really noticeable. So please tell us just what time to load you are seeing. Robert. On 28 August 2012 18:02, Boon Wah boon...@gmail.com wrote: Hi, I am a user of osgDEM and used this to generate a terrain database. When the terrain data is first loaded by osgViewer, there would be an initial load time. I am trying to reduce this load time drastically. I prepared two sets of terrain database for comparison of the initial load time. The first set has a flat terrain (i.e. all vertices have height z = 0) and the second set has uneven terrain (i.e. different vertices have different heights). Both database uses the same texture and have been compiled with osgDEM with the same parameters, with the exception the second set was provided with a DEM map. What I have found out is that the first set initial load time is much faster (more than 10x) than the second set. Why is this so, even the size of the textures and the number of vertices remain the same for the 2 sets? Thank you!

[osg-users] How to exclude LOD-disabled nodes from PolytopeIntersector results?
Hi, I have a CAD app in which I am using LOD nodes to hide features at different zoom levels. I have also implemented picking using PolytopIntersector similar to the example in the Quick Start Guide. I have noticed that the PolytopeIntersector returns intersections that include nodes which are turned off by the LOD. I would like to exclude these from the intersections. Does OSG provide a way to do this? ... Thank you!

Re: [osg-users] How to exclude LOD-disabled nodes from PolytopeIntersector results?
I solved my problem...
For reference, the code I am referencing from the OSG Quick Start Guide is this:
Code:
double w( .05 ), h( .05 );
osgUtil::PolytopeIntersector* picker =
new osgUtil::PolytopeIntersector(
osgUtil::Intersector::PROJECTION,
x-w, y-h, x+w, y+h );
osgUtil::IntersectionVisitor iv( picker );
viewer-getCamera()-accept( iv );
Shortly after I posted, I saw that osgUtil::IntersectionVisitor contains a
function setLODSelectionMode(). I tried setting this to
USE_EYE_POINT_FOR_LOD_LEVEL_SELECTION but it had no effect. I did a bit more
investigating and saw that this enum is referenced in
IntersectionVisitor::getDistanceToEyePoint(). However, LOD::traverse() calls
NodeVisitor::getDistanceToViewPoint(), which is not implemented in
IntersectionVisitor.
I was able to derive from IntersectionVisitor and implement
getDistanceToViewPoint() similarly to getDistanceToEyePoint():
Code:
if (_lodSelectionMode==USE_EYE_POINT_FOR_LOD_LEVEL_SELECTION)
{
return (pos-getViewPoint()).length();
}
else
{
return 0.0f;
}
then used the subclass in my picking code, after which I got the desired effect.
Is this something that should be added to osgUtil::IntersectionVisitor?
...
Thank you!
Cheers,
Michael

Re: [osg-users] [vpb] Speed of first frame rendering
Hi Roberto, My terrain database is about 3GB in size, and measures about 3 by 5 pixels just for the textures alone. I have written a single frame renderer based on the OSG Viewer code base. The load time for first frame rendering takes close to 10s for the DEM terrain database. My each tile size is around 8MB. For the flat terrain database, the load time is almost instantaneous ( 1s ).
