An in-depth tutorial on the principles of writing L-Systems in Houdini using examples from Aristid Lindenmayer's book 'The Algorithmic Beauty of Plants'.

After watching this tutorial you should be able to understand all the elements of an L-System, and be able to create your own from scratch.

Subjects covered are:

  • L-System Node (at 1:20 minutes)
  • Turtle Syntax (at 8:00 minutes)
  • Branching  (at 16:00 minutes)
  • Edge Rewrite (at 18:40 minutes)
  • Node Rewrite (at 24:30 minutes)
  • Symbol variables (at 31:35 minutes)
  • Using Custom Values (at 41:25 minutes)
  • Monopodial and Sympodial Trees (at 42:50 minutes)
  • Gravity (tropism) (at 43:50 minutes)
  • Ternary Tree (at 45:50 minutes)
  • Input Geometry in L-Systems (at 48:00 minutes)
  • Randomization (at 1:07:25 minutes)
  • Stamping Geometry (at 1:09:20 minutes)
  • Probability (at 1:20:25 minutes)
  • Conditionals (at 1:25:05 minutes)
  • Phyllotaxis (at 1:28:30 minutes)
  • Sunflower (at 1:33:05 minutes)

Houdini Kitchen tutorials are aimed at experienced 3D artists who are new to Houdini, and focus on creating procedural geometry for video games. Each tutorial covers a single node or concept, and will usually finish with a demonstration of how that tool might be used in asset creation. There are easier ways to use Houdini – commonly used nodes can be set up automatically using shelf tools, and useful networks are now embedded in higher level nodes – but I believe that to be able to fully harness the power of Houdini it is important to understand the basics. I have worked as a Technical Artist in the Video Game industry for 15 years, and my credits include Killzone 2 & 3, The Getaway 1 & 2 and Playstation VR Worlds. I have been learning Houdini since 2005, and have been using it in production for the last 5 years. I also have a degree in Archaeology and have completed several 3D projects for the British Museum.
