摘要
提出了一个多方法耦合的参数曲面分片重建新方法,即普通分片采用T-splines最小二乘拟合,而奇异点附近则采用T-NURCCs逼近。虽然不同分片的重建方法有别,但皆为T-splines表示,数据结构一致,生成方式统一。该方法适合于工业造型和其它复杂模型的重建。
A coupling method of surface patch reconstruction based on T-splines is presented. The least-square reconstruction method is employed in general patch, and the T-NURCCs at singular points. In spite of the differences of optimization strategies, they are all represented in T-splines, whose data structures and evaluation procedures are identical. The method is most significant to reconstruct complex models.
