List of Figures

Figure 5.1 : An out of focus moving disk
Figure 5.2 : A patch of 50000 curves rendered with opacity culling.
Figure 7.1 : Ray traced displacements
Figure 7.2 : An image rendered using an HDRI map and the `envlight2' shader. There is no "light sources" in the scene: the shadows are cast from bright regions in the environment.
Figure 7.3 : Teapot rendered with subsurface scattering enabled.
Figure 7.4 : Highly scattering materials (long mean free path) can benefit from higher shading rates.
Figure 7.5 : Outlines on Oi (opacity) and z (depth). Note how outlines get thinner with distance. Example scene available in `$DELIGHT/examples/toon'.
Figure 7.6 : Example of edge detection using normals.
Figure 7.7 : Ri plug-in filters lie between the program that generates the Ri calls (such as the RIB reader, renderdl) and the 3DELIGHT renderer.
