This suggest to me that one of the vertex attribute arrays has been
left enabled and the OpenGL driver is attempting to read from it past
the end of the data that had previous set up for that array. For
instance, perhaps the colour array is left on. Have a look at the
osg::Geometry::drawImplementation(osg::RenderInfo&) method, it has a
code block where it does:
state.lazyDisablingOfVertexAttributes();
// then does all the state.setVertexPointer(..) that are required
state.applyDisablingOfVertexAttributes();
// dispatch primitive data
Perhaps something like this would work for your app.
Robert.
