This simple function just performed a null check and an array lookup. Just writing it in the few places its used works fine too, and avoiding the function call per triangle can improve and make the check clearer. Also, avoiding the abstraction makes the "node fully visible" check when building the PBVH more obvious; that has been refactored here.
