We present a legorization framework that produces a LEGO model from a voxel model. Unlike other frameworks, we include bricks whose height is more than one layer. Furthermore, we devise a two-colored graph that represents the adjacency and stability information of a LEGO model. Our legorization is composed of tiling process on each layer, which is implemented using a heuristic search algorithm. We legorize five models including characters and buildings to prove the excellence of out framework
