R T _ P G F A C E This function is called with pointers to 3 points, and is used to prepare PG faces. ap, bp, cp point to vect_t points. Return - 0 if the 3 points didn't form a plane (eg, colinear, etc). # pts (3) if a valid plane resulted. Definition at line 144 of file g_pg.c.

R T _ P G _ P R E P This routine is used to prepare a list of planar faces for being shot at by the triangle routines. Process a PG, which is represented as a vector from the origin to the first point, and many vectors from the first point to the remaining points. Definition at line 79 of file g_pg.c.
