一個對於變動曲面的網格重構之研究

Abstract

我們提出了一個以提高網格質量的理念為基礎的重新網格化方法，利用一連串區域的運算來改進網格的幾何性質。其核心技術為Area-based smoothing ，此方法能建造一個非均勻網格，並且能有效地降低鈍角三角形的數目。

We present a remeshing scheme based on the idea of improving mesh quality by a series of local modifications of the mesh geometry and connectivity. The central local modification technique is an area-based smoothing technique. Area-based smoothing allows the control of both triangle quality and vertex sampling over the mesh, as a function of some criteria, e.g. the mesh curvature. The algorithm is able to create an unstructured mesh, and reduce irregular vertices efficiently.
