Seamless fracture in a production pipeline.

To alleviate the laborious task of generating volumetric fracture pieces by hand while preserving the integrity of the artistically modeled shape, we develop a practical, robust, and effective solution for artistically directed volumetric fracture. Unlike previous approaches our procedural fracture system maintains intrinsic attributes (e.g., texture coordinates), preserves discontinuities such as texture seams, and generates procedurally fragmented "chunks" with seamless boundaries. The key steps in our fracture pipeline are: robust scan-conversion from an input geometry, generation of fragmented fracture pieces with artistic control, and high fidelity mesh generation of the disjoint fracture fragments.
