OpenGL before you draw a scene, you need to create or define a scene, the process that produces the target scene view is similar to the process of photographing a camera.1. Secure the camera to the tripod and align it to the scene (view transform).2. Arrange the scene so that the position of each object in the photo is what we want (model change).3. Select the camera lens and adjust the magnification (projection transform).4. Determine the size of the final photo. For example, we would probably

Great trouble!
The number of each face of the cube is 0-5. The shape can be determined based on the vertex and the front. A total of 6*4 = 24 forms.
P [I] indicates the position where id I is located. For example, P [1] = 3 indicates that the second side is switched to the fourth side.
All forms are displayed.
At this time, you can manually calculate or write a function to find all the forms.
Note that you need to select function compute and put it out of main for convenient
