1. multi-ray shooting. It now shoots rays in all the 3 coordinate directions from the cell centre. Before it would shoot just a single ray from the nearest point on the surface, going through the cell centre. There is a cost overhead in that now it shoots 6 rays (+-x, +-y, +-z) instead of just 1. 2. bleeding of refinement. It marks the cells inside a gap and walks out the gap-size to neighbouring cells (which are just outside the gap). This should make for a smoother refinement pattern.
