基于PCL的点云配准处理主程序，基于点云库实现，可以进行点云的拼接(PCL-based point cloud registration processing main program, based on point cloud library implementation, you can point cloud of the stitching)

制作二维地形,并且可以对其添加线表示，还可以做分层设色二维地形图图(Dimensional terrain)

D3D开发的粒子系统应用，雪的效果逼真，算法经典。(D3D development of particle system applications, the effect of real snow, the classic algorithm.)

实现图像纹理特征的提取，并且完成了该项功能(The extraction of image texture features, and completed the)

有关Ogre中骨骼动画这方面的几份资料的汇总包括源码(For Ogre in skeletal animation in this regard, including a summary of several data source)

直接运行TestMyCrust.m, 读取点云txt,或者直接加载mat文件 运行需要几分钟，耐心等待 完成后运行trianglenormal.m, 生成三角面片的法向量 运行完成得到tri.txt（组成三角面片的点的编号信息）,trinormal.txt(每个三角面片法向量数值)，diandian.txt(每个点云信息) 然后将三个数据当做stl_gen.exe的输入文件，得到trisuface.stl文件(run TestMyCrust.m, read point cloud file txt, or load mat file)

三维点云数据读取并显示。格式为按行读取，坐标为（X,Y,Z）(3D point cloud data read and displayed. The format is read by line, the coordinates (X, Y, Z))

计算单应矩阵，输入为2D图像坐标点和3D世界坐标点，输出为3x3单应矩阵(Calculate homography)

说明：  一种改进的活动轮廓模型－－GVF梯度矢量流模型(Improved active contour models-- gradient vector flow gradient vector model)

说明：  访问最底层LOD模型路径，打开后获取顶点数据和PirmitiveSet，重绘模型的三角面片(Visit the bottom LOD model path, open it, get vertex Array and PirmitiveSet, and redraw the triangle of the model.)
