Function Documentation

void nmg_evaluate_boolean (  struct shell *  sA, struct shell *  sB, int  op, long int **  classlist, const struct bn_tol *  tol )

N M G _ E V A L U A T E _ B O O L E A N Evaluate a boolean operation on the two shells "A" and "B", of the form "answer = A op B". As input, each element (loop-in-face, wire loop, wire edge, vertex) in both A and B has been classified as being "in", "on", or "out" of the other shell. Using these classifications, operate on the input shells. At the end, shell A contains the resultant object, and shell B is destroyed. Definition at line 208 of file nmg_eval.c.

N M G _ E V A L _ A C T I O N Given a pointer to some NMG data structure, search the 4 classification lists to determine it's classification. (XXX In the future, this should be done with one big array). Then, return the action code for an item of that classification. Definition at line 293 of file nmg_eval.c.
