Some of Tor Olav's POV-Ray Images

To create the shapes in these images I have used three different techniques:
Isosurfaces, NURBS meshes and Constructive Solid Geometry (CSG).
No NURBS primitives are available in POV-Ray, so I have made POV-Ray macros that can generate
univariate NURBS (e.g. curves), bivariate NURBS (e.g. surfaces) and trivariate NURBS (e.g. mesh deformations).
I have provided the source code for some of the images.
