Zusammenfassung:•We 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. 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.
