2215 メッシュデータに対する高品質細分割曲面の当てはめ(OS4-2 自由曲面モデリング,OS4 デジタルエンジニアリング)
詳細
We present a method to construct a control mesh of a high quality subdivision surface. Our method assumes that the given triangular mesh is a control net of a Loop subdivision surface. The initial mesh is simplified using Quadric Error Metrics (QEM) algorithm. The initial control mesh is obtained by fitting simplified mesh using weights for each valence of points. The control points are iteratively updated using coefficients which are obtained by calculating weights for one control point of Box Spline. We demonstrate effectiveness of the presented method for closed objects.
