Re: [osg-users] OSG 3.0.1 crash in glDrawElements() under Windows Remote Desktop

iirc osg can statically link with opengl lib, so you can make 2 binaries: one with mesa statically linked in, and other using whatever opengl32.dll system have. Cheers. 31.05.2012, 23:04, "Simon Hammett" :On 31 May 2012 17:17, Andrew Cunningham wrote:When running a Windows OSG 3.0

Re: [osg-users] Enabling notifications from within program?

Hi You can set your own notify handler like this to check if you ever get messages from osg: class NH : public osg::NotifyHandler { public: NH() : m_out("osg_log.txt") { } ~NH() { m_out.close(); } void notify

Ok, thanks for that idea. I will definitely look into using Mesa. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=47985#47985 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.

[osg-users] osgDB::readImageFile don't work correctly

Re: [osg-users] Building a slimmed down static version of OSG

Quick follow up: The error seems to occur when linking using GCC 4.4.2, which is part of the tool chain I use. When I use my distro's GCC 4.7 to do a static build with the same CMake settings, I don't get the error. To get around it in 4.4.2, I explicitly defined requestRedraw() in GraphicsWindowE

Hi, When you load data from a file like an obj using the function osgDB::readNodeFile is there any way to access the arrays containing vertex coordinates, normal coordinates and texture coordinates associated to the object? I want to design a way to detect which rendered object user is touching

Re: [osg-users] Advice on scene structuring

Hi, Filip Huge count of unique statesets can have big influence on framerate. Also implementing just transform in vertex shader, but still drawing each object separately would not help you much. Dont know how you can implement picking with instanced drawing (may be keep another scenegraph with

Re: [osg-users] Advice on scene structuring

Hi Filip, I don't understand very well why instanced rendering is not an option, but anyway if you are reaching the limits of your hardware you can make an extra pass and use a geometry shader to discard instances (something like it's done in [1]). Other way is going for a multiresolution strateg

Re: [osg-users] Advice on scene structuring

Hi, I have similar problem. But instanced rendering is not an option, because I want to draw different huge number of objects from time to time. Now I share geometry (can't share Geode because of picking - every object has to be different) between PositionAtitudeTransforms. It's pretty fast, but

Re: [osg-users] OSG fragment shader

[osg-users] Help:Problem with LineSegmentIntersector. Maybe a bug?

Re: [osg-users] Enabling notifications from within program?

Hi Preet, The osg::notify system isn't related to handling of std exceptions except where some specific code might catch an exception and report the output to osg::notify. This means that upping the notify level won't effect how exceptions are handled. The best thing to do is run a debugger and

[osg-users] Explanation of macros in staticviewer example?

Hiya, In the osgstaticviewer.cpp example, there are three sets of macros: USE_OSGPLUGIN()... USE_DOTOSGWRAPPER_LIBRARY()... USE_SERIALIZER_WRAPPER_LIBRARY()... When compiling a static application, how do we know which ones we need to include? It seems like they're all related to osgDB with USE_O
