feature preservation in view-dependent multiresolution meshes
Normal vector discontinuities on surfaces provide important visual cues for understanding the image of a geometrical object since they often indicate feature boundaries. We present an algorithm that preserves the appearance of features in view-dependent multiresolution meshes. The algorithm is shown to be efficient in terms of time and memory consumption. Our method is compatible with geomorphing to eliminate popping artefacts in interactive applications, and it can also be applied to texture coordinates. A large set of examples demonstrates the benefits of the proposed algorithm.
