  abstract =   "In this paper, a simple and efficient solution for combining
               shear-warp volume rendering and the hardware graphics
               pipeline is presented. The approach applies an inverse warp
               transformation to the Z-Buffer, containing the rendered
               geometry. This information is used for combining geometry
               and volume data during compositing. We present applications
               of this concept which include hybrid volume rendering, i.e.,
               concurrent rendering of polygonal objects and volume data,
               and volume clipping on convex clipping regions. Furthermore,
               it can be used to efficiently define regions with different
               rendering modes and transfer functions for focus+context
               volume rendering. Empirical results show that the approach
               has very low impact on performance.",
