三角域上三阶T-Bézier曲面片的构造与设计
Construction and design for three order T-Bézier surface on triangular domain
摘要
Abstract
In computer aided geometric design, T-Bézier curve and surface is viewed as new free form curve and surface modeling tools have been widely studied, but the surface is all tensor product. In order to further study T-Bézier in non-polynomial space and perfect the theory of triangular domain, a kind of trigonometric basis for trigonometric polynomial space over triangular domain is proposed. The constructed basis over triangular domain has been proved to have nice prop-erties such as positivity, partition of unity, symmetry, boundary representation and linear independence and so on. Some properties of the corresponding surface are also proved. Finally, some applications of the proposed basis are shown.关键词
