“…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.

“…The last image shows this ball broken into two pieces, that allows us to see clearly its internal structure composed of explicitly modeled grains. We use [MGD*04] method to create the global fracture shape from a real world image. The fracture is propagated along the grains boundaries.…”

Light-matter interactions is one of the most important factors of realistic rendering. While a lot of work has already been performed in the light transport and simulation area, we believe that "virtual materials " have not yet been studied enough to achieve a high degree of realism. Some good models exist in order to take into account homogeneous materials. However, there are only a few studies of heterogeneous granular materials. In this paper, we propose a method based on mimicking natural phenomena to take into account these materials. Our study focuses on granite, which can be considered as a heterogeneous agglomerate of individually homogeneous grains. First we present a nucleation/growth process inspired technique giving a full 3D model of granite. Then, we use a rendering process taking into account each material component and subsurface scattering in a simple way.

“…Wyvill et al [26] form cracks based on the Distance Transform algorithm on a 2D surface to replicate Batik painting cracks. Martinet et al [27] learn crack patterns from a real picture, map them to an object's surface, carve out a volume to generate crack depth and then break the object into fragments.…”

We present an approach for animating cracks and fractures in cartoon style. In our method we take a 2D handdrawn object as input and then construct a 2.5D model of the object in order to approximate the object volume. Next, we generate the Voronoi textures on the 2.5D object model for visual abstraction of cartoon cracks. Further, cracking gaps on the Voronoi textures are widened progressively until Voronoi cells split apart and finally fall onto ground according to simplified physical rules. With minimum user intervention, our model is able to generate cartoon cracks and fractures animations procedurally, as demonstrated by examples given in the paper.
