DrawPicture

openGl大作业，包含光源，移动物体，简易动画，纹理场，建筑等。(openGl large operations, including light, moving objects, simple animation, texture field, construction and so on.)

点云数据转换文件。可以将PCL转换为PLY文件，反之亦然。其中用到了点云库PCL的代码。(Point cloud data file conversion. PCL can convert PLY files, and vice versa. Which uses a point cloud library PCL code.)

无人机路径规划。在给定的三维空间中搜索一条安全可行的无人机飞行路径(Path Planning. In a given three-dimensional space to search for a safe and feasible UAV flight path)

说明：  c++的绘制二维等值线源码。有示例数据，可以运行。(c++ two-dimensional contour map of the source。c++ code for contour map)

演示地形绘制与漫游，取自OGRE例子，地形管理器会自动应用八叉树分割来管理地形。(Demo terrain rendering and roaming, from OGRE example, terrain Manager automatically applied octree division to manage the terrain.)

OpenDwg的DRXSDK开发包，是DRX程序的二次开发包，有加强使用DRX的CAD用户可以下载(OpenDwg the DRXSDK development kit is the secondary development of DRX procedure package, enhancing the use of DRX have the CAD users can download)

结构光三维重建代码，提取结构光的点，并进行三维坐标转换(Structure light 3D reconstruction code, structured light extraction point, and three-dimensional coordinate conversion，DrawZeroPoint/Structure-Light-Reconstructor)

说明：  给出一些离散的点，根据最小二乘法求出拟合的直线。(If there are some discrete points, you can get a line based on least square method.)

Visual C++结合OpenGL做的一个3D场景。其中包含地形生成，场景漫游，碰撞检测，场景中模拟了河流，跳跃的鱼，喷泉，树木，水草，房屋，塔楼，楼梯，飘动的旗帜等等。第一人称视角，可以跳跃行走碰撞检测，模拟了白天黑夜等等！(Visual C++ with OpenGL to do a 3D scene. Which contains the terrain generation, scene roaming, collision detection, simulation of the river scene, jumping fish, fountains, trees, plants, houses, towers, stairs, waving flags and so on. First-person perspective, you can skip walking collision detection, simulation of the day and night, and more!)
