A split is when a branch separates itself into two branches.

The split node takes a tree, and replaces each segment of branch by a split with a certain probability. The splits are extremities that can then be grown using the grow node.

Parameters

• proba: Probability of replacing a branch by a split.
• split_angle: Angle between the branch branch direction and the secondary split direction.
• spin: Rotation between each split.
• head_size: Size of the secondary branch compared to the main one.
• offset: Number of branches that wont be split before the first split occurs.
