Abstract
Normal meshes were recently introduced as a new way to represent geometry. A normal mesh is a multiresolution representation which has the property that all details lie in a known normal direction and hence the mesh depends only on a single scalar per vertex. Such meshes are ideally suited for progressive compression. We demonstrate such a compression algorithm for normal meshes representing complex, arbitrary topology surfaces as they appear in 3D scanning and scientific visualization. The resulting coder is shown to exhibit gains of an additional 2-5dB over the previous state of the art. 1 Introduction The unrelenting growth of computing power of personal computers and recent progress in shape acquisition technology facilitate the wide use of highly detailed meshes in industry and entertainment. Similarly, scientific visualization applications tend to produce ever finer meshes, such as iso-surfaces. In their raw, irregular form, acquired meshes are complex and often unmanageable du...
