Procedural modeling of cracks and fractures

This work presents a procedural method for modeling cracks and fractures in solid materials such as glass, metal and stone. Existing physically based techniques are computationally demanding and lack control over crack and fracture propagation. Our procedural approach provides the designer with simple tools to control the pattern of the cracks and the size and shape of fragments. Given a few parameters, our method automatically creates a vast range of types of cracks and fragments of different shapes.
