Contour-Edge Based Polyhedron Visualization. Lutz Kettner. In: Proc. 16th European Workshop on Computational Geometry, Eilat, Israel, pp. 77-80, 2000.
We present a new approach to computing visibility for three-dimensional polyhedral surfaces based on contour edges. The advantages are supported by our extensive experimental study of contour edges [Kettner & Welzl 97]. We describe preprocessing possibilities for contour edges, a fast silhouette computation algorithm, a new object-space hidden-surface removal algorithm for three-dimensional polyhedral surfaces, and its specialization for terrains.
