输入参数即可获得相应的饼图和柱形图。如：别克，丰田，捷达 会出现比例大小的图-Get input parameters corresponding pie and bar graph. Such as : Buick, Toyota, the Jetta will map the size ratio

// TetGen computes Delaunay tetrahedralizations, constrained Delaunay tetra- // // hedralizations, and quality Delaunay tetrahedral meshes. The latter are // // nicely graded and whose tetrahedra have radius-edge ratio bounded. Such // // meshe

三维变换包括几何变换和投影变换。 几何变换有平移、旋转、对称、错切、变比。 投影变换有平行投影和透视图。,Three-dimensional geometric transformations, including transformation and projection transformation. Geometric transformations are translation, rotation, symmetry, shear, variable ratio. Parallel

在P4P问题中,当空间4个点共面时,不仅摄像机坐标系与物体坐标系之间 的旋转矩阵R和平移向量t可以线性求解,而且可以同时确定摄像机的有效焦距f和像素比例，该程序设计模拟已知相机矩阵M情况下由已知三维空间点和图像坐标情况求解相机外参数矩阵-When space four points coplanar P4P problem, not only between the camera coordinate system and the object coordinate system rotatio
