Yes, I did make a tree using the idea of a binary tree.
The whole tree is generated by building sub-branches recursively until the branch is too short. Based on what I did for NOC animation class, I added a noise variable to every node and change its value every frame so that the tree is moving gently.
Here is the code on Github
I have been thinking of how to make the branches getting thinner naturally instead of having a static light weight throughout a branch. Also, what would be a better way to add leaves?
