[DirextX] Cube DL : 0: 帮助D3D学习者了解向量与矩阵运算。实现效果：指定世界空间中的任意位置作为原点，指定任意长度作为旋转半径，立方体围绕圆心旋转。-D3D assist learners know vector and matrix operations. Achieve results: the designated space in the world at any position as a starting point, designated as the rotation radius of arbitrary length, cube rotating around the center of a circle.

[DirextX] 8.5 DL : 0: 8.5 以点（point）类为基类，重新定义矩形类和圆类。点为直角坐标点，矩形水平放置，由左下方的顶点和长宽定义。圆由圆心和半径定义。派生类操作判断任一坐标点是在图形内，还是在图形的边缘上，还是在图形外。缺省初始化图形退化为点。要求包括拷贝构造函数。编程测试类设计是否正确。-8.5 point (point) class is the base class, redefined class and rounded rectangle class. Points for the rectangular coordinates, horizontal rectangle, length and width from the lower left vertex and definitions. Defined by the center and radius of the circle. Derived class action to determine coordinates of any point within the graph or the edge of the graph, or in the graphics outside. Degradation as the default initialization point graphics. Requirements include copy constructor. Programming test class design is correct.
