代码说明:

本源码完整给出了一个接口函数; 用户只需要给出一个模型文件名称,函数返回需要的8个OBB的顶点; 算法使用开源osg作为基础库函数,先抽取模型的所有的点,接着计算协方差矩阵,继而求解三个特征向量作为OBB的三个轴;在此基础上给出模型OBB的八个顶点;

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

    现图形学中画直线,园和圆弧以及直线裁剪,区域填充等功能 1. 对于画直线,只需知道起点和终点即可。在工作区间中按下鼠标(即选择起点),拖动至另一处松开(终点),即得到直线。 2. 画圆需要圆心坐标、半径、及起始角和终止角,至于实验要求的画1/4圆弧,可设起始角=0,终止角=45,若要画整个圆弧起始角和终止角分别为0和360即可。-Graphics are painting a straight line, arc, as well as garden and cut a straight line, filled with features such as region 1. For painting a straight line, just know that you can start and finish. Interval in the work of the mouse click (that is, to choose the starting point), drag to another release (the end), that is to be a straight line. 2. Drawcircle need to center coordinates, radius, and the termination of the initial angle and angle, as required by experimental painting 1/4 arc, the starting angle can be set = 0, terminate the angle = 45, in order to draw the whole arc start angle and termination angle is 0 and 360, respectively, can be.
