 ==== Normal Groups ====
-The normal groups is a list that matches each normal to a triangle. It is formed in pairs with the first item being the index of the normal, and the second item being the index of the triangle.
+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.
-Normal groups are sorted by polygon index. Only floors & ceilings are referenced by the normal groups, walls are given the first index of the normals list (-1,-2,-3,-4).
+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.

+For any of the camera values, 9999 can be used to disable reading that value. For a pair, -9999 is used in the first member and 9999 in the second member to disable them.
+Certain values are only used if the bool enables them. For example a focus pos is only used if that axis is locked.
+The bounds variables basically set limits on how far the camera moves before panning to face kirby instead of scrolling.
