Interactive shape metamorphosis

ABSTRACT

Image metamorphoses (morphing) is a powerful and easy-to-use tool for generating new 2D images from existing 2D images. In recent years morphing has become popular as an artistic tool and is used extensively in the entertainment industry. In this paper we describe a new technique for controlled, feature-based metamorphosis of certain types of surfaces in 3-space; it applies well-understood 2D methods to produce shape metamorphosis between 3D models in a 2D parametric space. We also describe an interactive implementation on a parallel graphics multicomputer, which allows the user to define, modify and examine the 3D morphing process in real time.
