| The normal groups are a binary space partition tree of the level normals and corresponding triangles associated with those normals. Each normal group represents a node in the tree, and has a right and left child based on whether the ensemble of triangles is in front or behind the parent node. | The normal groups are a binary space partition tree of the level normals and corresponding triangles associated with those normals.

| - | The first index of the normal group is (-1,-2,-3,-4), the search through the tree starts at the last member in the array, indices of zero refer to leaf nodes. | + | If a triangle group intersects a normal, then the group is split and the normal is repeated in both the left and right children. If that group shares a condition such as being breakable, then the entire group is repeated in the left and right branches. |
