Hi Stephan,
I haven't merged your change as is, but have merged and checked in the
more succinct implementation:
_isTexture3DSupported = OSG_GL3_FEATURES ||
isGLExtensionSupported(contextID,"GL_EXT_texture3D") ||
strncmp((const
char*)glGetString(GL_VERSION),"1.2",3)>=0;
Let me know if this works fine, thanks,
Robert.
