The main goal was to get visframe out of mnode_t to make it thread-safe (each thread can have its own visframe array), but moving the plane info into mnode_t made for better data access patters when traversing the bsp tree as the plane is right there with the child indices. Nicely, the size of mnode_t is the same as before (64 bytes due to alignment), with 4 bytes wasted. Performance-wise, there seems to be very little difference. Maybe slightly slower. The unfortunate thing about the change is the plane distance is negated, possibly leading to some confusion, particularly since the box and sphere culling functions were affected. However, this is so point-plane distance calculations can be done with a single 4d dot product. |
