What you'll learn
This tutorial introduces us to using L-systems within a procedural scene set up to make a group of growing trees. In this tutorial we will learn the basics of using L-systems with turtle functions, randomness, gravity and metaballs to sculpt the set. Our system will then be run to create a small forest of growing trees. Software required: Houdini 11.0.
