Hi all, I built the osg2.9.7. I tried to create the project with the OSG_GL3_AVAILABLE, and he rest GL flags disabled. But when I run the simplest example, osgviewer with the cow.osg to render, it renders nothing and display warnings as "TexGen::apply - not supported" and some other stuff. I dug into the code and found that this is due that I disabled the OSG_GL_FIXED_FUNCTION_AVAILABLE.
Does it mean that with OpenGL3 there is not fixed pipeline and all should be written by shaders? What about the projections of the objects from the 3D world to the camera plan, are they done by OpenGL or should I write them too? And if all should be done by shaders, does it mean that most of the code of OSG won't work under GL3 if no appropriate shaders would be written? Thanks, Guy.
