I played with the new sample scenes for isosurface shaders, found the
speed differences quite interesting.
The shader rmf was much slower than the hardcoded ridgedMF function, but
with the torus shape the shader lies just between hardcoded and directly
written function. This means that the compiled shaders are significantly
faster than the current isosurface function interpreter. I don't know
what optimizations are planned for Povray 3.5 in that direction - just
wanted to share this observation.
