Re: [osg-users] osgWidget performances
Hi, The masks was a good idea, and there is a little bit improvement but not enough in my case... I'm still trying to make some improvement using them, but without the expected success. So if you have any other idea... please share it ! Thanks. Regards, Vincent Le 16/04/2012 17:27, Kim Bale a écrit : Whilst I haven't used osgWidget, I know we had a similar performance issue with picking when we didn't use an appropriate node mask for picking so that only the pickable objects in the scene are considered. I wonder if osgWidget has implemented one in it's pick handler. Regards, Kim.

Using profiler co, I found that the osgWidget::WindowManager::pickAtXY function is very expensive in time... Here is my question : this method is called on every event, specially on mouse move and click, event if the mouse is not over Widgets... Is there any reason to make this ? Can this be improved, for example doing it only if the mouse is over the widgets, using a simple XY square test... Thanks for your answers.

I'm not that familiar with osgWidget but change WindowManager.cpp to use a local IntersectionVisitor to traversal just the osgWidget subgraph rather than the whole scene graph this way the performance won't vary with the main scene graph.

[osg-users] What can cause glCompileShader FAILED?
Hi all,
Can someone explain what can cause a shader to not compile? I have a two
programs with nearly identical build systems, using the same OSG libraries
(3.1.1) on the same machine. One can compile and run shaders, while the other
produces this:
Code:
Compiling VERTEX source:
1: // microshader - colors a fragment based on its position
2: varying vec4 color;
3: void main(void)
4: {
5: color = gl_Vertex;
6: gl_Position = gl_ModelViewProjectionMatrix * gl_Vertex;
7: }
VERTEX glCompileShader FAILED
Compiling FRAGMENT source:
1: varying vec4 color;
2: void main(void)
3: {
4: gl_FragColor = clamp( color, 0.0, 1.0 );
5: }
FRAGMENT glCompileShader FAILED
Linking osg::Program id=0 contextID=0
glLinkProgram FAILED
I am invoking it in a standard way like this:
Code:
osg::Geode* geode = new osg::Geode();
geode-addDrawable(new osg::ShapeDrawable(new osg::Box(osg::Vec3(1,1,1), 1)));
root-addChild(geode);
osg::Program * prog = new osg::Program;
prog-addShader ( new osg::Shader(osg::Shader::VERTEX, microshaderVertSource )
);
prog-addShader ( new osg::Shader(osg::Shader::FRAGMENT, microshaderFragSource
) );
geode-getOrCreateStateSet()-setAttributeAndModes( prog,
osg::StateAttribute::ON );
It has to be something in my scene graph. Some state being inherited, or some
setting that I'm unaware of. Any help would be greatly appreciated.
Extra info:
OSX=10.7.3, osgversion=3.1.1, GPU=nvidia GeForce 8600M GT

Hello Mike,
maybe it is easier for us to follow if you elaborate in what the nearly
identical build systems differ.

Re: [osg-users] What can cause glCompileShader FAILED?
Hi Sebastian, Indeed, I now realize that it is some sort of build setting! To clarify, the program with broken shaders was built with XCode, while the one that works was built with an autotools project. Both link with the same libs and have all the same flags (I think; will verify). Furthermore, I just tried to build the broken program using an autotools system and the exact same code works... so it definitely a setting in my XCode project. I'll poke around to see if I can find the setting, but if anyone knows of an XCode flag that would prevent shaders from working, I'd be grateful to know. -Mike -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=47122#47122 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Character modeling + Cloth simulation + Blender osgExporter
Hi, Thank you for replying. Glad to see that other people are using Makehuman + OSG. I reported some issues about the exporter at : https://github.com/cedricpinson/osgexport/issues/10#issuecomment-4973016 If I understand, do you export in fbx from Blender ? Are there some reasons why you preferred to export in .fbx instead of .osg ? While trying to export a clothed model to .fbx and displaying the .fbx file with QuickTime, I got the skin as peeking through the clothing as in Makehuman GUI. Have you also encountered problems about exporting the eyebrows with .fbx format ? I had such a problem while exporting to OSG from Blender. This problem does not occur while importing to 3DSMAx as. obj file from Makehuman and exporting to OSG with the MaxExporter. About the clothing with Makehuman model, could you explain more about how you did it ? As far as I understand, MakeHuman uses masks to hide the parts of the body which are covered with clothes, so there is no UV map for clothes. Also, did you use the MHX tools (MHX expression, MHX Lipsync) for animation ? If so, did they export well with fbx ? A great lab in Geneva, Miralab, works a lot on cloth simulation and they are using OSG as their 3D engine. I read an interesting thesis report using Poser + OSG from their lab (“Virtual mirror” by using real-time motion capture” … Thank you!

[osg-users] How to use CMake to construct an OpenSceneGraph project ?
Hi,
I have just downloaded the OpenSceneGraph source, unzip it into
~/OpenSceneGraph-3.0.1 directory and use CMake to create an out-of-source
eclipse make project in ~/OpenSceneGraph-3.0.1-build-eclipse-cdt
directory. When I execute make in
~/OpenSceneGraph-3.0.1-build-eclipse-cdt directory, OpenSceneGraph builds
successfully. I have not run sudo make install as I do not want to
install OpenSceneGraph tightly into my Ubuntu system.
Now I want to use CMake to create a project using the compiled
OpenSceneGraph libraries. I use the following codes in CMakeLists.txt :
CMAKE_MINIMUM_REQUIRED(VERSION 2.6)
PROJECT( test_proj )
FIND_PACKAGE(OpenSceneGraph)
ADD_EXECUTABLE( test test.cpp )
INCLUDE_DIRECTORIES(${OPENSCENEGRAPH_INCLUDE_DIRS})
TARGET_LINK_LIBRARIES( test ${OPENSCENEGRAPH_LIBRARIES} )
But it seems that OpenSceneGraph could not be found by CMake.
Does anyone know how CMake could find the compiled OpenSceneGraph
libraries in the ~/OpenSceneGraph-3.0.1-build-eclipse-cdt directory and
use it to create projects as if I have tightly installed OpenSceneGraph
using sudo make install. Thanks for any suggestion.
Lawrence
