The 3D Illusion

So, how do we go from 2 dimensions and make the illusion of 3 dimensions?
The normal 2D shapes that we were working on with the last exercise are changed slightly as follows:

Triangle = Pyramid








Circle = Sphere

(I know that the circle/sphere doesn't look that different now, but just wait until you shade it and give it a shadow.)




Square = Cube







It takes both shade and shadow to give the illusion of the 3rd dimension.

Next time: I'll finish the exercise myself, and show you the results.
