绘制若干OpenGL基本体素（三角形、三角形带、四边形、四边形带）构成的球体，注意球体绘制与球体划分的区别。

 　　可以控制改变球的数量和球的体积，来改变基本体素的数量以及顶点的数量。

 　　可以通过改变glPolygonMode，切换是否填充所绘制的基本体素。

 　　利用函数glutGet(GLUT_ELAPSED_TIME)（returns the time in milliseconds since glutInit or the first invocation of the function）统计绘制时间

-Basic OpenGL rendering voxel number (triangle, triangle strips, quadrilateral, quadrilateral zone) constitutes the sphere, drawing attention to the sphere and the sphere by the difference. 　The number can control the ball and the ball change the volume, to change the basic number of voxels and the number of vertices. 　You can change the glPolygonMode, is populated by switching the basic voxel rendering. 　Using function glutGet (GLUT_ELAPSED_TIME) (returns the time in milliseconds since glutInit or the first invocation of the function) Statistics drawing time
