Processing codes to generate fractal trees.

How to run the code:

Install processing and run the code fractal_tree.pde

Commands:

• Position of mouse: changes the origin of the tree.
• a: decreases the angle used to create the branches.
• z: increases the angle used to create the branches.
• e: the length of a new branch is the length of the previous branch times a ratio. It decreases this ratio.
• r: the length of a new branch is the length of the previous branch times a ratio. It increases this ratio.
• t: decreases the lenght of the first branch.
• y: increases the lenght of the first branch.
• u: the branches are created recursively until they are attaining a certain lentgh. It decreases this length.
• i: the branches are created recursively until they are attaining a certain lentgh. It increases this length.
