碩士 === 國立中央大學 === 資訊工程研究所 === 89 === A view-dependent multiresolution modeling with appearance attributes based on the quadric error metrics for real-time visualization is proposed. The multiresolution modeling technique can rapidly produce high-quality approximations of the origin model based on the quadric error metrics. The view-dependent refinement improves the visualization performance. In addition, a generalized form of the quadric error criteria can accommodate vertices with appearance attributes, such as RGB color and texture coordinates; this virtue makes the multiresolution models more reasonable. Moreover, we record the appearance properties during constructing the multiresolution models such that we can reduce the calculation time during rendering the models.
