Abstract
The use of reflection lines and specular high lights for the quality control of car body surfaces is an important issue in the development process of a car. The interactive examination is based on standard graphics tools such as the SceneViewer of OpenInventor which simulates re ection lines by using striped environment maps. The interpolation of texturing and shading values is critical and requires high quality meshes. Thus, element shape and size are essential. In this paper we present a new technique for the tessellation of trimmed surfaces. The result of the algorithm is a 2-manifold mesh with a low triangle count and a triangulation pattern which is best suited for the visualization.
