# Homework 4: L-systems


Medieval scene in Houdini

## Process

1) Inspired by this tower tutorial I started building a procedural growing tower but modified it to make it my own.

2) Built an LSystem for the procedural generation of the metal stair supports.
3) Built an LSystem for the random looking plants inside the tower to give it a more organic feel. Built off one of the houdini built in functions.
4) Built an LSystem for the the spherical decorations that repeat through the tower openings.
5) Added fracture effect based on the Houdini guest lecture to give rock like appearance to the tower.
6) Applied rock material, metal material and environment background hdri material for the background. The hdri is taken from https://polyhaven.com/
7) Added hdri environment light and spot light to cover some parts that remained dark.
8) Played with DOF and created multiple renders.

For this assignment, you will design a set of formal grammar rules to create
a plant life using an L-system program. Once again, you will work from a
TypeScript / WebGL 2.0 base code like the one you used in homework 0. You will
