碩士 === 國立交通大學 === 資訊工程系所 === 94 === Many simplification methods have been proposed to generate multiresolution models for real-time rendering applications. Practitioners have found that these methods fail to produce satisfactory result when models of very low polygon count are desired. This is due to the fact that the existing methods take no semantic or functional metric into account, and moreover, each simplification metric has its own strength and weakness as well in preserving geometric features. To overcome such limitations, we propose an interactive system that allows users to refine unsatisfactory regions on any level of simplification. Our approach consists of two stages. The first stage involves modifying the simplification order to postpone the collapsing for edges in the unsatisfactory regions. The second stage is a local refinement tool aiming to provide fine tuning on the simplified meshes. The major advantage of our approach is that our system provides a predictable and quantifiable control over the refining process. The system is packed as a 3ds Max plugin, so users can easily integrate our system into the digital content creation process.
