DrawingView

对图片进行网格划分，以及绘图获得区域，最终获得灰度矩阵(Mesh the image, and draw the region to obtain the gray scale matrix)

L曲线选择正则化参数,适用于正则化算法中选取正则化参数反演( L-curve)

代码是关于Peano-Hilbert曲线算法，属于图形学范畴(Code is on the Peano-Hilbert curve algorithm, belongs to the category Graphics)

用于求解各阶贝塞尔函数和汉克尔函数零点，希望对大家有帮助。(besselj and hankel functions)

手动绘制点，自动生成样条曲线，可以拖动修改点来修改样条曲线(Manually plotting points, automatically generated spline curves, you can drag the modified point to modify the spline)

说明：  用VB编写的简易的绘图程序，用来绘制直线圆和矩形，可以选择绘图颜色和画笔粗细。(VB, easy to use drawing program, circles and rectangles to draw a straight line, you can select the drawing pen color and thickness.)

可以实现基本的绘图功能，画直线，矩形，圆椭圆。图形学作业(Can achieve the basic drawing functions and draw a straight line, rectangle, circle, ellipse. Graphics jobs)

分形几何是数学领域里新兴的课题,如果将图形的每个元素按某种规则进行变形,得到新的图形,以此类推,进行若干次变形后得到的图形就是分形图形。本程序实现分形图。(Fractal geometry is the mathematical field of emerging issues, if the graphics of each element according to certain rules of deformation, new graphics, and so on, to carry out a number of graphics after deformation is fractal graphics. This procedure realize fractals.)

off 转stl ，很好的转换软件源码。实现了off三维格式向stl三维格式转换，可用于CAD、ProE等软件对接。( Turn off to stl, good conversion software source code. Off to achieve a three-dimensional format stl three-dimensional format conversion, it can be used in CAD, ProE and other software docking.)
