- Child index
- If the high bit is not set then the child index is the index of another quadtree node (into the same array). Otherwise it is the index of an OTLF entry.
- U and V meaning
- X aligned node - U = Y, V = Z
- Y aligned node - U = X, V = Z
- Z aligned node - U = X, V = Y
- Note
- The alignment of a node depends on the leaf face that referenced it because there is no orientation information in a quadttree node.
