| Multiresolution modelling is a good method to achieve both quality and performance in the rendering of complex scenes. Within this framework, the detection and preservation of outstanding features, such us silhouettes, become very important. The goal of this paper is to present a technique based on Distance Transforms that allows to classify the elements of the mesh according to their proximity to both the internal and the external contours and makes use of this information for weighting the approximation error which will be tolerated during the mesh simplication process. The approach used in this work precomputes silhouettes for a given set of cameras and performs an estimation for any other point of view. The results obtained are evaluated in two ways: visually and using an objective metric that measures the geometrical difference between two polygonal meshes. | |
