sph - create a sphere
SYNOPSIS
sph vc rad
DESCRIPTION
Create a sphere made of the current material with its center at the named vertex vc and a radius of rad. If the vertex is undefined an error will result.The surface normal is usually directed outward, but will be directed inward if the given radius is negative. (This typically matters only for one-sided materials.) A zero radius is illegal.
