微分几何的电子书，很经典的书，通俗易懂,如果要学习微分几何，推荐(this is a book about differential geometry)

Delaunay三角剖分的一个程序，一个方法。属于计算机图形中的计算几何。对于有限元分析有着重要的意义。(Delaunay tri-decomposition program)

Grass文件夹下为分形草的程序源代码，程序运行后，只需要按空格键就可以随机产生不同的分形草图形(Grass folder for grass fractal source code, the program running, just a space bar can be different randomly generated fractal graphics grass)

对图像进行几何变换，如旋转，缩放，镜像，裁剪等。(Image geometric transformations such as rotation, scaling, mirroring, cropping and so on . )

基于特征的影像匹配——SIFT Method!!! 相当经典,只不过是MatLab源码(Based on the characteristics of image matching, SIFT Method!!!!!!)

实现对任意多边形的三角形凸分解。(To realize arbitrary triangle polygon convex decomposition.)

光学图像的几何仿真，采用已有的光学图像作为参考，布置在传感器照射范围区域，然后根据卫星轨道、姿态等获得新的图像，该图像能够反映原始图像的几何特性(Optical image geometry simulation, using the existing optical image as a reference, arranged in the area illuminated area of ​ ​ the sensor, then the satellite orbit, attitude and so obtain a new image, the image can reflect the geometric properties of the original image)

分形几何算法案例，基于MFC实现 Sierpinski垫片算法(Fractal geometry algorithm case, MFC-based implementation Sierpinski algorithms)

说明：  用VB写的mondebroot集，鼠标选中区域可放大显示(VB wrote mondebroot set, the mouse can enlarge selected regional show)

二维图形几何变换的实现，MFC，平移、比例、对称、旋转等(The realization of two-dimensional graphics geometric transformation, MFC, translation, proportion, symmetry, rotation, etc.)
