Introduction to nodes

When looking at a tree, one can easily identify a logic in the structure of the tree. First, rising from the floor you can see a trunk. Then, the trunk is divided into big branches, that are divided into smaller branches, and so on.

The use on the node editor allows to reproduce this process. First, a trunk is generated with an input node. From that point it is considered to be a tree.

The tree functions make the tree grow, which means that branches are split, and extremities are grown.

Finally, the output node allows the tree to be displayed into the 3d view, and takes care of the leaves/twig distribution.

The beauty of this process is that the tree functions can be stacked any number of times, which different controls applied so that the user has a fine control over the tree.
