Not necessarily...the speed of an isosurface can vary a lot. Some are 
faster than most of the other shapes available(isosurface 
superellipsoids are faster than ordinary superellipsoids, for example). 
Others are extremely slow. In my experience, avoiding functions with 
high slope helps a lot. These seem pretty simple, noise3d() displaced 
cones, spheres, etc. They should render pretty fast if only one 
noise3d() is used. I don't know about the ridged multifractal though...I 
have never used it.
