3D Metamorphosis Between Different Types of Geometric Models

Abstract: We present a powerful morphing technique based on level set methods, that can be combined with a variety of scan conversion/model processing techniques. Bringing these techniques together creates a general morphing approach that allows a user to morph a number of geometric model types in a single animation. We have developed techniques for converting several types of geometric models (polygonal meshes, CSG models and MRI scans) into distance volumes, the volumetric representation required by our level set morp… Show more

“…Besides collision detection, distance fields have a wide range of applications. They have been used for morphing [41,42], volumetric modeling [43,44], motion planning [45] and recently for the animation of fire [46]. Distance fields are sometimes called distance volumes [41] or distance functions [47].…”

“…This is done by walking in the normal direction of the interface with a distance proportional to the target signed distance map value. In [9] a level set approach for morphing between signed distance maps is presented. Here signed distance maps are constructed from a characteristic scan conversion algorithm, and a similarity measure is formulated as a functional.…”
