Or you could just do it on the fly.

Trace takes an object id, a start point, a direction, and (optionally) a
previously-#declared vector in which it stores the surface normal at the point

The aforementioned normal vector is set to <0,0,0> if the trace fails to hit
anything. Test the length of this vector using vlength().
