| Outline of Research at the Start |
本研究では、メッシュを構成する三角形パッチの頂点の最小角および最大角を改善し、低品質の要素を除去することで、分子表面メッシュの品質を向上させる再メッシュ法について提案する。この方法では、分子表面形状のパターン解析を行い、その結果に基づいてメッシュを分割し、各分割された領域ごとに再メッシュ化を行う。また、分割された領域ごとの計算をＣＰＵのマルチスレッド処理やGPUを用いて並列化することで、計算効率を効率化する。さらに、ユーザビリティを向上させるために、エンドユーザー向けに使いやすいインタフェースやソフトウェアツールを提供する。

| Outline of Annual Research Achievements |
We have started with a systematic literature review to find state-of-the-art algorithms for surface remeshing. The paper has been accepted with IEEE TVCG, which a very good journal in computer graphics. Then we have proposed a novel algorithm for valence optimization and angle improvement of molecular surface remeshing. The proposed algorithm starts with CVT initialization followed by edge-based operations for angle improvement and valence optimization. The proposed method segments the input meshes in segments and then remeshes the segments in a divide-and-conquer manner. We have tested our algorithm on a number of models and have found it with better performance. A part of the proposed algorithm was presented in MICAD an International Conference. Similarly, the remaining work is accepted for presentation in Computer Graphics International. The paper has also been recommended for the journal publication in “The Visual Computer” Journal. In short, our results have been published in two International conferences and two Journal Articles.
