Abstract. Being able to find the silhouette of an object is a very important front-end processing step for many high-level computer vision techniques, such as Shape-from-Silhouette...
Phong-shaded 3D imagery does not provide geometric information of the same richness as human-drawn technical illustrations. A non-photorealistic lighting model is presented that a...

The Fourier projection-slice theorem allows projections of volume data to be generated in O(n2 log n) time for a volume of size n3 . The method operates by extracting and inverse ...
We present a novel and effective method for modeling a developable surface to simulate paper bending in interactive and animation applications. The method exploits the representat...
—We study the topology of the Megaparsec Cosmic Web on the basis of the Alpha Shapes of the galaxy distribution. The simplicial complexes of the alpha shapes are used to determin...
