The article focuses on animating fractures and cracks patterns in 3D solid objects. According to the author animators use three main techniques to generate synthetic motion, keyframing, motion capture, and procedural methods. Keyframing and motion capture both require that motion be specified by some external source. In contrast, procedural methods compute original motion automatically. The computer graphics literature includes many examples of passive systems modeled with simulation. In 1999, a simulation technique that uses nonlinear finite element analysis and elastic fracture mechanics to compute physically plausible motion for 3D solid objects as they break, crack, or tear was developed. This technique allows fractures to propagate in arbitrary directions by dynamically restructuring the elements of a tetrahedral mesh. In the computer graphics literature, two previous techniques were developed for modeling dynamic fracture caused by deformations.
