DEM数据处理，有贴纹理及漫游程序，自己在其他网上下载的 希望对做三维的朋友有所帮助(DEM data processing, has the stick texture and roaming)

3d 图形学的 算法，包含源代码(3d graphics algorithms, including source code)

用于各种特征提取主成分分析法，如表情提取，人脸提取，识别分类等(For a variety of features to extract the principal component analysis (pca)，Such as expression extraction, face extraction, identification classification, etc)

交通标志检测,pic文件夹下为实验用的交通标志图,这是我们小组的研究性学习课题.(Traffic sign detection, pic folder for the experimental use of traffic signs, which is our group of research learning topics.)

说明：  对三角划分算法的研究，对以前方法的改进，以达到良好的效果，(Triangulation algorithm to study the improvement of previous methods in order to achieve good results,)

这是学习CVI关于网络设置方面的一个很有价值的例子(to study how to use cvi)

denary三角剖分算法源码，用于离散点成面，自动构建面的高级算法，该算法非常难得，希望你们有所启发。(denary triangulation algorithm source code for the discrete points into face, the face automatically build senior algorithm, which is very rare that you have inspired.)

这个事关于Computer Graphics （计算机图形学）的教学代码！！！(The thing about Computer Graphics (computer graphics) teaching the code! ! !)

扫描线Zbuffer算法 1。算出模型的包围盒。 2．每条扫描线打点时并不是包围盒内整条线打点，而是先搜索需要刷新的范围， 只是该范围内打点。 (One scan line Zbuffer algorithm. Calculate the model bounding box. 2. Each scan line runs inside the box when not surrounded by the entire line runs, but first need to refresh the scope of the search, but the scope of RBI.)

对图像的对角线投影，就是沿着对角线进行直方图统计。(Diagonal projection of the image, that is, along the diagonal histogram statistics.)
