Parametric surfaces are a powerful and popular modeling tool in computer graphics and computer aided design, while ray tracing is a versatile and very popular rendering technique. As a result, there...
Ray Tracing of Geometric Primitives According to the RenderMan-Standard (2007)
Swen Campagna, Wolfgang Heidrich
Ray Tracing of high-quality images has two basic requirements: a renderer and a modeler. Usually, communication between those two is done by a specified file-format. Each renderer capable of that...
Abstract Interactive Multi-Resolution Modeling on Arbitrary Meshes (2007)
Leif Kobbelt, Swen Campagna, Jens Vorsatz, Hans-peter Seidel
During the last years the concept of multi-resolution modeling has gained special attention in many fields of computer graphics and geometric modeling. In this paper we generalize powerful...
Computer Graphics Group (2007)
Swen Campagna, Leif Kobbelt, Hans-peter Seidel
Due to their simplicity triangle meshes are used to represent surfaces in many applications. Since the number of triangles often goes beyond the capabilities of computer graphics hardware, a large...
A general framework for mesh decimation (1998)
Leif Kobbelt, Swen Campagna, Hans-peter Seidel
The decimation of highly detailed meshes has emerged as an important issue in many computer graphics related fields. A whole library of different algorithms has been proposed in the literature. By...
