This is quite a challenge. The idea is to draw an anamorphic cube so that the image, once projected onto a curved surface looks like a cube. You will find the template or graph for this exercise on Mathspig here.
It took me several goes to get it … sort of … right.
Step 1: Make silver foil/cardboard cylinder to fit the dotted circle on the grid below.
Step 2: Draw in the corners of the cube on the square grid and match these corners on the curved grid.
Step 3: Draw in the three vertical sides of the cube and match these lines on the curved grid.
Step 4: Draw in the top and bottom horizontal sides of the cube on the square grid and match these on the curved grid.
Getting tricky now.
Step 5: Draw in the blue, orange and green sides of the cube on the square grid and match these on the curved grid.
Step 6: Place silver cylinder on dotted circle.
Step 7: Can you see the cube?
Step 8: Here’s a closer look.
An even better Anamorphic Cube.
