Cracking is a natural phenomenon commonly observed on the surface of such objects as concrete, clay walls, rice fields, pottery, and tree barks. This paper describes a new physically based method for synthesizing 3D cracking patterns in clay solids by incorporating a moisture model. We employ actually measured values of the physical parameters used in the model. In addition, we describe a new method for dealing with a 3D freeform object based upon the close-packed structure. Animated synthesis of not only external cracks but also internal cracks of 3D freeform solids is possible.
