Hey !

Another try on my Game of Life simulation: this time, the goal was to make it a little better-looking. It was a great opportunity to get my hands on the wonderful shine library, and to work with tweening libraries (which I didn't use in the final version).

Get it here. :-)

Today I stumbled upon a really cool wikipedia article which deals with a remarkable subject: quadtrees. As it says,

a quadtree is a tree data structure in which each internal node has four children.


Let me show you an example for you to visualize this:

The implementation is fairly simple, and I wanted to go a bit further. That's when I found koalastothemax. It is a quadtree implementation applied to an image : basically, for each child, you have to compute its colour, which is the average of all the image's pixels colours inside it.

Here's the result:
