You either specify point vectors or float-vector pairs. If the latter, 
the result is similar to crackle with the solid feature turned on, 
except that it uses the specified value for that cell rather than a 
pseudo-random one. The points can be whatever you want...mesh vertices 
would work, but you would have to extract the actual vertex locations.

voronoi {
    offset FLOAT
    form FLOAT
    metric FLOAT (actually a vector, but only the x component is used)

    POINTS
}

POINTS:
    VECTOR,
    VECTOR,
    VECTOR...
or:
    [FLOAT VECTOR]
    [FLOAT VECTOR]
    [FLOAT VECTOR]

You must specify at least 3 points, but that is the only restriction.
