可以进行空间曲面的拟合 用于曲面拟合的代码：圆 球 直线 平面拟合都有(Surface fitting code: round ball linear plane fitting)

实现了DDA直线生成算法画直线，Bresenham圆弧生成算法画圆弧(Achieve DDA line drawing algorithm to generate a straight line, Bresenham algorithm for drawing arcs arc generated)

说明：  在inkscape中将矢量图转成gcode(Converting Vector Graph to gcode in Inkscape)

3次B样条小波程序，用MATLAB写的，思想简单，但要建立好像不容易，大家看看(3 bspline wavelet program,using matlab language.The idea is not complex,but it is not easy to realize it.Hope all read.)

这是NURBS曲线的绘制程序，在MATLAB-2008a环境下进行编写，包含了几个基函数子程序。可以通过调节控制顶点和点的权重来调节曲面形状。 (This is a NURBS curve drawing program, in the MATLAB-2008a environments prepared, including a number of basis function subprogram. Can be controlled by adjusting the weight of vertex and point to adjust the surface shape.)

产生一批随机数，使用TeeChart进行绘图。是TeeChart学习很好的程序。(Produce a random number, using TeeChart for drawing. TeeChart learning process is good.)

用于拟合椭圆的函数，支持对于多个离散数据点的椭圆曲线方程计算(new function)

fiala轮胎模型的建立以及根据试验数据修正后的轮胎模型建立及其新轮胎特性曲线的绘制。(establish fiala tire model and the mapping of the establishment of the tire according to the revised model test data and a new tire characteristic curve.)

采用层次包围盒、八叉树加速的光线跟踪算法(ray tracing using level boundary box and eight branch tree algorithm)

说明：  实现对单图层dxf文件的信息采集，例如直线的起止点、圆弧的圆心与半径等(Achieving Information Collection of DXF Files with single layer)
