摘要： Disclosed herein is a fracture pattern generation apparatus for a crumbling effect includes a graph generation unit, a fragment center setting unit, a fracture pattern generation unit, and a fragment mesh generation unit. The graph generation unit generates the graph of the mesh model by filling the inside of a mesh model with a plurality of vertices and connecting the vertices using line segments. The fragment center setting unit sets the central vertices of fragments, which are separated due to fractures, from among the plurality of vertices formed on the graph. The fracture pattern generation unit generates the fracture pattern by setting the central vertices of the fragments to terminal vertices of the fracture pattern and allocating Identifications (IDs) to the respective the central vertices of fragments. The fragment mesh generation unit generates fragment meshes by performing division on the graph based on the fracture pattern.
