Crack Pattern Simulation Based on 3D Surface Cellular Automaton
This article describes a method for modeling the propagation of cracks on any 3D surface. This method allows almost any type of cracks on any type of triangulated 3D object. Our model’s main advantage is that it proposes a semi-physical solution, making it both user controllable and easily extensible. We first introduce the general development of cracks. We then present our original model of spectrum stress, followed by a description of the mutual interaction between cracks and stresses. Then, we describe special rendering techniques including the multi-thickness anti-aliasing linkedsegmentmethod and the crackmirror special effect. The final section presents intermediate graphical results that review the entire model as well as a set of different crack patterns using various types of material such as concrete, ceramic,mud, and glaze.
