| Summary: | 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.
