Abstract

Presents anatomy-based muscle models for the human body aimed at realistic surface form. Muscles are represented with anatomically motivated primitives, including ellipsoidal and multi-belly muscle models, whose shape changes as joints articulate while preserving volume and producing bulging. The muscle layer drives the deformation of an overlying skin, giving figures realistic surface form that responds to pose, a foundation for muscle-based character deformation.

How to read this

Category: Method: anatomy-based human muscle modeling
Contributions: Anatomically motivated muscle primitives, including ellipsoidal and multi-belly muscles
Volume-preserving bulging as joints articulate
Muscle layer drives realistic skin deformation
Context: Companion in spirit to anatomically based modeling and a descendant of layered character construction, focused on the human musculature.Builds on: Layered Construction for Deformable Animated Characters
Correctness: Anatomy-inspired rather than physically simulated; volume preservation and bulging are modeled geometrically, which is enough for convincing form.
Clarity: Well organized around muscle types, with clear figures of bulging behavior.
How to read it: First pass: the muscle primitives and how they change with joint angle. Second pass: how the muscle layer drives the skin.
