Grow node
The grow node takes a tree in input, search for all it's extremities and makes them grow for a number of iterations, or until a certain width is reached.
Since the node has a lot of parameters, it has an advanced settings checkbox so that the more rarely used parameters are not always displayed.
-
limit method: when will a branch stop growing:
- radius: when a certain radius is reached.
- iterations: when the branch has been grown for a number of iterations.
- branch_length: Length of each portion of branch generated.
- randomness: intensity of the noise affecting the direction of each branch.
- radius_decrease: Radius of each branch iteration compared to the previous one.
- gravity_strength: Amount of downward attraction.
- split_proba: Probability for a branch to split.
- split_angle: When a branch is splitting, the angle between the branches of the split
- split_deviation: When a branch is splitting, the angle between the split and the previous branch
- split_radius: When a branch is splitting, the radius of the secondary branch of the fork
- spin: Relative rotation of a split compared to the previous split in the branch
- spin_randomness: Randomness of the spin
- pruning_strength: Decrease the probability of branching when the density of branches is high
- shape_factor: Decrease of branching probability when the branch is far from the axis of the tree
- up_attraction: Favour branches going up
