  • Feature request: ZigZag branching patterns.

    In a lot of pants and trees, there is an interesting phenomenon noticeable for which the scientific name sadly eludes me.
    When branching occurs, a sort of zigzag pattern along the parent branch manifests itself.

    Example 1.
    Example 2.
    Example 3.

    I've managed to crudely approximate this effect by using a 'directional force' and modifying it's profile curve, but this technique is tedious, labour intensive and the results aren't very good. The biggest limitation is that it's not interactively linked to the actual distribution of the child nodes. If that changes, the zigzag pattern is immediately out of sync.

    I'd love to be able to have a control in SpeedTree that automatically does this based on the placement of any generated child node. Including more subtle side effects such as the gentle bulging and seaming that occurs at the branching points.

    Thanks for reading!
