When the two-dimensional cross-sectional geometry, plane geometry, three different dimensional alignment. The resulting images of the cross section in the three-dimensional geometry of different looks different.
When the plane is two-dimensional geometric patterns cut across a three-dimensional geometry in various genres. Image and three dimensional geometric patterns cut in a different way, there will be a different style.
When the two-dimensional plane geometric figures and three-dimensional geometric figure across the different concepts in the image of the cross-shaped three-dimensional geometric concepts in a different way is different.
