Abstract
This paper presents a simple, effective method for constructing elbow and knee joints between rigid NURBS-based human body segments for animation. The purpose is to automatically and efficiently manipulate NURBS joint patches to provide smooth, realistic joint action. The production of fine surface detail is also illustrated by creating wrinkles in the joint acute angle, also in a simple, effective manner. By automating such processes the need to manually add surface detail is reduced; animator input and animation time is decreased.
