The Research on Approximation of Bezier Surface based on Curved Triangle Patchs
基于曲面三角形逼近的Bezier曲面表示研究
In chapter two, using piecewise quartic polynomial as kernel function, we give analytical convolution solutions for points, line segments, arcs, quadratic Bezier curves and triangle segments.
在第二章中，我们采用截断多项式函数为核函数，解析的给出点、直线段、圆弧、二次曲线和三角面片等骨架的势函数。
In this thesis, we give analytical convolution solutions for points, line segments, arcs, quadratic Bezier curves and triangle segments, and present a fast ray tracing algorithm of convolution surfaces.
本文解析给出点，直线段，圆弧，二次曲线和三角面片等骨架的势函数，并且提出一种快速的光线跟踪绘制卷积曲面算法。
The algorithm is based on the triangle Bezier fractionization of existed triangle grid, the normal vectors of the three vertexes of subtriangles are recalculated through quadric interpolation and the realistic rending method of subtriangles is still Gouraud shading.
这种算法在对已有的三角网格进行三角Bezier细分的基础上，仅对细分后的子三角形顶点进行法矢二次插值优化，细分后的子三角形的真实感显示仍旧采用Gouraud明暗处理来改善效果。
