[vtkusers] deriving a GPU Raycasting mapper from vtkVolumeMapper

[Oliver Joy]

Hi vtkusers,

I wrote a GPU Raycasting mapper derived from vtkVolumeMapper based on the framework of the paper:

[SSKE05] S. Stegmaier, M. Strengert, T. Klein, and T. Ertl. A Simple and Flexible Volume Rendering Framework for Graphics-Hardware-based Raycasting, Proceedings of Volume Graphics 2005, Stony Brook, New York, USA, pp.187-195, 2005 

I wrote the code following the vtkVolumeTextureMapper3D style. I still have problems about this mapper. It seems that the pipeline dosenot execute the Render() method in my derived mapper. I want to know how the rendering pipeline is executed in a vtkVolumeMapper. Could anyone help me and figure out my mapper? Thanks!
