绘制P-Bezier曲面的matlab程序，不同于传统的Bezier曲面，P-Bezier曲面仅含纯三角多项式。压缩包中，DrawPBezierSurf.m文件可运行，其中可以设置控制顶点和形状因子，可以更改控制网格的颜色。程序对任意m*n阶的P-Bezier曲面均适用。-Draw P-Bezier surfaces matlab program, unlike traditional Bezier curve, P-Bezier surfaces containing only pure trigonometric polynomial. Compressed package, DrawPBezierSurf.m files can be run, where you can set control points and form factors, you can change the color of the control grid. Program for any m* n-order P-Bezier surfaces are applicable.
