该程序是Cassini椭圆函数的等高线曲线，再VC++MFC环境下用OpenGL绘制，本程序采用的方法是利用插值法求得等高曲线和单元边线的交点，函数在50*50的单元栅格上采样。,The program is Cassini cnoidal contour curves, and then VC++ MFC with OpenGL rendering environment, the procedure adopted is to use obtained by interpolation co

使用内插算法画出B曲线：即与两条直线相切并且无限靠近直线交点的曲线-Interpolation algorithm used to draw B curve: ie as close as two lines and a straight line tangent to the curve of intersection

matlab检测直线交点源程序在matlab6,5下已调试通过 不错的-Matlab detection line intersect point source in matlab6, have been debug through good under 5

用水平扫描线从上到下扫描由点线段构成的多段构成的多边形。每根扫描线与多边形各边产生一系列交点。将这些交点按照x坐标进行分类，将分类后的交点成对取出，作为两个端点，以所填的色彩画水平直线。多边形被扫描完毕后，填色也就完成。(A polygon consisting of a plurality of segments consisting of a line segment from bottom to bottom by horizontal scanning. Each scan line p
