point_t plane_pt

ray/plane(face) intercept point plane_pt is the intercept point of the ray with the plane of the face. Definition at line 2317 of file raytrace.h. Referenced by isect_ray_planar_face().

fastf_t ray_dist_to_plane

ray parametric dist to plane ray_dist_to_plane is the parametric distance along the ray from the ray origin (rd->rp->r_pt) to the ray/plane intercept point Definition at line 2322 of file raytrace.h. Referenced by isect_ray_planar_face().

int face_subhit

the "face_subhit" element is a boolean used by isect_ray_face and [e|v]u_touch_func to record the fact that the ray/(plane/face) intercept point was within tolerance of an edge/vertex of the face. In such instances, isect_ray_face does NOT need to generate a hit point for the face, as the hit point for the edge/vertex will suffice. Definition at line 2331 of file raytrace.h. Referenced by isect_ray_planar_face().

int classifying_ray

the "classifying_ray" flag indicates that this ray is being used to classify a point, so that the "eu_touch" and "vu_touch" functions should not be called. Definition at line 2337 of file raytrace.h. Referenced by classify_seg(), isect_ray_planar_face(), nmg_class_ray_vs_shell(), rt_nmg_shot(), and shoot_and_plot().
