摘要: | 在三维电脑绘图里网格参数化一直以来都是很基本且重要的问题,它可被运用于许多的电脑绘图领域,如贴图(texturing mapping)、贴图合成(texture synthesis)、互动式三维描绘(interactive 3D painting)、网格重建(remeshing)、多解析度分析和网格压缩(multi-resolution analysis)。之前的参数化演算法都是自动且全域性的达到最小失真参数化,但是这种最小失真的参数化不一定适合于每个电脑绘图领域,如网格重建。在这篇论文里,我们提出一个可让使用者调整局部的参数化的架构来改善网格重建的品质。 Surface parameterization is a fundamental problem in computer graphics. It is very useful in many applications such as texture mapping, texture synthesis, interactive 3D painting, re-meshing, multi-resolution analysis, and mesh compression. However, previous parameterization methods automatically and globally balanced the distortion of area or angle in the embedding functions. Such a parameterization may have low distortions but might not be suitable for some applications, such as remeshing. In this thesis, we present a framework that allows users to locally adjust the parameterization intending to improve the perceptual quality of remeshing. |
