Detailed Description

The indices can optionally be cached in a VBO, so that they do not need to be send on each render call. This class is mainly needed because the OIV index structures typically contain -1 as marker for the end of each primitive, which is undesired for sending indices to OpenGL. Currently a single indexer only manages the kind of primitives that are passed in the constructor. (MeVis ONLY)
