Pre-Integrated Volume Rendering

10.1 Introduction to Pre-Integrated Volume Rendering
The basic idea of pre-integrated volume rendering is the precomputation of parts of the volume rendering integral. In this sense, it is similar to volume rendering using splatting and even more similar to the accelerated evaluation of the volume rendering integral within a tetrahedron proposed by Max et al. [12]. However, pre-integrated volume rendering is a more general concept that can be applied to many volume rendering algorithms (Section 10.2) and supports several different rendering techniques (Section 10.4). There is also particular research interest ...
