L-system

Creates fractal geometry from the recursive application of simple rules.

This tool is useful for simulating flora such as trees, shrubs, corals etc.

Placing an L-System in the viewer

To...Do this

Place the L-System anywhere in the scene

  1. Click the L-System button on the Create tab.

  2. Move the cursor into the scene view.

    Note

    You can hold Alt to detach the L-System from the construction plane.

  3. Click LMB to place the L-System anywhere in the scene view and press Enter to confirm your selection.

    If you press Enter without clicking, Houdini places the L-System at the origin.

Place the L-System at the origin

Press Ctrl + LMB on the L-System button on the shelf.

Note

L-systems can be moved once they are placed by either dragging them in the scene view or changing the values in the parameter editor.

Default L-Systems can be chosen from the Gear drop-down menu at the geometry level.

L-System Handles

The L-System does not have its own rotation parameters; however, you can rotate it at the object level using the handles in the scene view or by adding a Transform node at the geometry level.

Note

The origin of the L-System is at the base of the tree, not the middle of the object.

For specific parameter help see the L-System node help.
