- 主要模拟了荡漾的水面，使用的方法是：随机给定矩形水面四个角的高度，用随机中点位移法生成一幅分形水面，然后使水波按照一定的传播机制扩散、衰减，从而模拟出水波荡漾的效果。-simulated a ripple on the surface, the methods used are : to set random four corners of the rectangular surface and with a random midpoint displacement method generat

- 两条直线的起始点，终点，四个点，判断有无交点，并说明交点是实点，还是虚点-Two straight lines starting and end points, four points, to determine whether the point of intersection, and that intersection is a solid point, or virtual point
BSPLINE
- 这是BSPLINE测试程序，鼠标单击4个点后生成3次b样条，使用qt4.8.5 + vs2008编译 内含可执行文件，支持定点拖拽-This is BSPLINE test program that generates click four points after three b-spline, use qt4.8.5+ vs2008 compiled containing the executable file, and support drag control point
Bezier
- 三次贝塞尔曲线的实现 四个给定点p0,p1,p2,p3,在平面或在三维空间中定义了三次贝塞尔曲线。曲线起始于p0 走向p1，并从p2 的方向来到p3。一般不会经过p1或p2；这两个点只是在那里提供方向资讯.-三次贝塞尔曲线的实现 四个给定点p0,p1,p2,p3,在平面或在三维空间中定义了三次贝塞尔曲线。曲线起始于p0 走向p1，并从p2 的方向来到p3。一般不会经过p1或p2；这两个点只是在那里提供方向资讯. Realization of the three Bessel curv
