Side Note

Doing the project is fun.

It's just like creating a new world with different speices(classes) beginning from nothing.

About the Penrose Triangle

As you may notice in one of the referenced clips from youtube, there exist an Escher's solution to this so called "Impossible Triangle". Yet the one implemented in our program is also famous for its simplicity.

About the Impossible Cube

Similar to the Penrose Triangle, there exist an Escher's solution to this cube. The one modeled here basically follows the most significant features of the solution, except that some of the tiny curved parts are replaced by straight lines.

About the Fractal Tree

Calculation the transformation matrix which applied on each edge is a lot of fun, yet annoying~!

About the Twisted Patch

Again, fine-tuning the control points is time consuming. =]

About curved objects

When finding the control points on a plain, Photoshop did give a great help by simulating the exact curve you need.
