Analysis-suitable T-splines form a practically useful subset of T-splines. They maintain the design flexibility of T-splines with an efficient and highly localized refinement capability, while preserving the important analysis-suitable mathematical properties of the NURBS basis. The present paper proposes a new evaluation algorithm for analysis-suitable T-splines. The algorithm is based on the control polygon directly and it reduces both time and storage cost comparing with Bézier extraction.

适合分析的T样条曲线的de Boor评估算法

适合分析的T样条曲线是T样条曲线的实用子集。它们保留了T花键的设计灵活性，并具有高效且高度局部化的细化功能，同时保留了NURBS基础的适合分析的重要数学属性。本文提出了一种适用于分析的T样条的新评估算法。该算法直接基于控制多边形，与Bézier提取相比，可减少时间和存储成本。
