Similarly, the attached c++ test case is more in line with our
original code. It uses a color array that is updated each frame. The
array is flagged as dirty with a call to dirty(), but here also, no
VBOs seem to get used.
Forgot to mention that the original symptom we had was that the
dirty() call on the color array did not update the rendering. There
are fairly recent posts on osg-users that suggest that that call
should be enough, but we could not get it to work, hence the
simplified test case.
And to rule out that the opengl tracer is at fault here I just tried a
very simple VBO example (http://www.songho.ca/opengl/gl_vbo.html) and
when run the call trace indeed show relevant OpenGL VBO calls...
