Program and calculate the positions of eight corners, then connect lines and fill them.

I can only say this principle because I seldom do this effect.

=====================================

If you can't even understand this explanation, I think you really shouldn't realize this function, because it is very difficult to do this effect with pure animation in theory. ............

The coordinates of eight corners of a cube in three-dimensional space are calculated by using mathematical theory, and then displayed on the platform coordinates. ............
