For testing purposes I would like to plot a large number of objects using a
function. I want the scene to render as quickly as possible. Which primitive
should I choose? What other settings should I enable/disable?

Spheres would be the cheapest shape. Obviously turning off reflection
and refraction would make it faster. If you also turn off diffuse and
turn up ambient there would be no need for shadow calculations and no
need for light sources. You'd get a very boring rendering (just
colored circles) but it would render quickly.

A quick way to reduce rendering time is by decreasing the quality setting (+Q from the
command line).
The example in the POV docs of implementing a ray tracer in the SDL uses only spheres,
I believe. With spheres you can do planes, then with a CSG you can do basically
anything.

OK, thanks!
