Hi Aitor, The warning you are getting "OpenGL version test failed, requires valid graphics context." suggests that you are trying to do rendering from a thread that doesn't have a graphics context current. I know nothing about how you are setting up your graphics context or how you manage you fra

[osg-users] Shader problem on nvidia card

Hi, I have a problem when I apply a shader to an object in osg. I tried it on two machines. One with an intel G41 graphics card, which does not give me any problem, and the other is a NVidia GTX 480, which gives me the problem. When osg try to compile the shader, skip the following error: FRAG

Re: [osg-users] Shader Problem

hi CG when you remove a shader, osg::Program need to be relinked. this is done by osgUtil::GLObjectVisitor in osgViewer::Renderer::draw method. So this seem can be done at runtime. Which OSG version did you use ? Did you use osgViewer ? David Callu 2008/6/12 CG <[EMAIL PROTECTED]>: > Hi all,
