“…One type of approach maps some form of procedural crack pattern to an object's surface [16] and then carves out a volume to generate crack depth [18,5]. Others form cracks on a 2D surface to replicate Batik painting cracks [35] or create cracks similar to an input image [20].…”

a b s t r a c tWe present a method for generating surface crack patterns that appear in materials such as mud, ceramic glaze, and glass. To model these phenomena, we build upon existing physically based methods. Our algorithm generates cracks from a stress field defined heuristically over a triangle discretization of the surface. The simulation produces cracks by evolving this field over time. The user can control the characteristics and appearance of the cracks using a set of simple parameters. By changing these parameters, we have generated examples similar to a variety of crack patterns found in the real world. We assess the realism of our results by comparison with photographs of real-world examples. Using a physically based approach also enables us to generate animations similar to time-lapse photography.

“…In computer graphics, crack patterns can be applied to ceramics [12], to soil [13] and, more generally, to any object represented as a 3D mesh [14]. Geometric models propose algorithms to get crack patterns close to those produced by nature [15]. In contrast, physical approaches propose the models which tend to accurately simulate the dynamics of natural crack patterns.…”

“…For an overview which also includes surface cracks see Muguercia et al [6] for a publication on fracture modelling. A popular approach is to pre-compute a crack pattern and later apply it to the three-dimensional object, which avoids expensive stress computation at run-time [7][8][9][10]. This is often referred to as prescoring.…”
