Jacques Lucke Covers Working With the New LSystems Node in Animation Nodes 2.1.
The latest Animation Nodes includes a new LSystems node letting you create the classic fractal branching forms right within the AN toolset. The new node will take a text input allowing you designate when you want the system to move forward or to turn.
Animation Nodes Creator Jacques Lucke walks through how to work with the new L-Systems node, starting out with the basic premise, then expanding into more complicated things, including animation and motion graphics examples.
L-Systems are only available in Animation Nodes v2.1 and above, visit the release page for more information.
