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
