Chapter 7. GPU-based Volume Rendering Techniques

In this chapter, we will focus on:

• Implementing volume rendering using 3D texture slicing

• Implementing volume rendering using single-pass GPU ray casting

• Implementing pseudo isosurface rendering in single-pass GPU ray casting

• Implementing volume rendering using splatting

• Implementing the transfer function for volume classification

• Implementing polygonal isosurface extraction using the Marching Tetrahedra algorithm

• Implementing volumetric lighting using half-angle slicing
