Abstract

This chapter introduces techniques used in muscle Modeling and rendering. An anatomically based approach to muscle Modeling is presented in which the muscle models are generated from anatomical data. These models provide a good visual description of muscle form and action and represent a sound base from which to progress further towards medically accurate simulation of human bodies. Deformation of these models is also performed on the basis of their anatomical structures. The result is an efficient, anatomically accurate, muscle representation that is specifically designed to accommodate the particular form of deformation exhibited by each individual muscle.Muscle rendering is addressed in two radically different ways. In the photorealistic approach, the muscle texture is generated from anatomical data, and a texture synthesis method is used to simulate the fibre patterns on the muscle surface. In the non-photorealistic method, the muscles are rendered directly from volumetric data using a pen-and-ink styles. This provides a useful alternative to traditional visualisation techniques.
