摘要: 通过构造一个矩阵转换算子,将q-贝齐尔曲线/曲面转化为贝齐尔曲线/曲面,然后利用贝齐尔曲线光滑拼接的条件完成q-贝齐尔曲线/曲面的光滑拼接,从而给出q-贝齐尔曲线/曲面的光滑拼接的一个几何条件。

Abstract: By constructing a matrix transformation operator, the q-Bezier curves/surfaces are transformed into Bezier curves/surfaces. Then, by means of the smooth connection conditions on Bezier curves/surfaces, the geometric continuity conditions on q-Bezier curves/surfaces are given.

Key words: q-Bernstein basis, matrix transformation operator, geometric continuity, conversion matrix
