opengl从text里读取数据点的坐标，然后在opengl里画图-opengl read from the text in the coordinates of data points, and then drawing in opengl

单文档读取txt文档，将得到的数据生成点并连接成线。单文档读取txt文档，将得到的数据生成点并连接成线。-Single document to read the txt file, the data obtained from the generation point and connected into the line. Single document to read the txt file, the data obtained from the generation point and

读取散乱的三维点数据，并实现三维显示，提供各种旋转，读取的是txt文件-Read the scattered 3D point data, and to achieve a three-dimensional display, offers a variety of rotation, read txt file

基于OpenGL的三维点云数据显示，可以选择浏览文件读入点云市局，鼠标点击、拖动和滑动可实现三维图形的旋转和缩放，最大可读入一百万个点，点云数据存在txt文件中，数据格式分别为x、y、z的坐标，具体以压缩文件中的3dcloud.txt为例-OpenGL-based 3D point cloud data show, you can browse the file is read into the point cloud PUC, mouse click, drag and swipe reali
