11        /*** This module is used by LODTree to simplify leaves of a tree. It contains functions that generate simplified
12        versions of 3D objects made out of quads (represented as pairs of texture-mapped triangles). Given a 3D object, this
13        module computes a sequence of geometric transformations that reduce the object’s geometric detail while preserving
14        its appearance.\n\n
15
16        For each simplification step, the module returns a simplification sequence containing the leaf collapsed, the two
17        leaves being removed, and the resulting leaf for that contraction.\n\n
