Hi Fred -- If you want some basic shape support combined with use of buffer
objects, you should consider osgworks.googlecode.com, which contains convenience
functions to create some basic shapes using osg::Geometry objects (which
supports use of buffer objects). If you need shape metadata (sphere radius, box
extents, etc) you can store that information as UserData on the Geometry objects.

Hi,
setUseVertexBufferObjects(true) has no effect for me with the code below:
Code:
osg::Geode* geode = new osg::Geode();
geode->addDrawable(new osg::ShapeDrawable(new
osg::Cylinder(osg::Vec3(4.4f,0.0f,0.0f),1.0f,1.4f)));
geode->getDrawable(0)->setUseVertexBufferObjects(true);
When I run this code with an OpenGL API tracer, I can see display lists are
still being used (glNewList to build the display list, then glCallList to use
it).
This test is easy to reproduce with the osgShaders sample, in GL2Scene.cpp,
CreateModel() can be changed to reflect the above code.
I guess I must be doing something wrong to make use of VBOs.
Any idea?
Cheers,
Fred
