L-Systems Node

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’ (1:39:07 minutes)

How to create L-Systems

Using examples from: The Algorithmic Beauty of Plants: http://algorithmicbotany.org/papers/abop/abop.pdf Contents To see the full turtle sequence being generated by an L-System open up an HScript Textport (alt+shift+t) And type: opinfo /pathto/L-SystemYou can drag the L-System node into the textport to get the path automatically. Turtle sequence The basic L-system commands are used to draw a line […]

UV Tools

This Tutorial is an Overview of all the different nodes available to create UVs in Houdini, and also covers setup, display and previewing of UVs and textures in Houdini, and demonstrates a quick way to display PBR textures. (57:21)

Copy Stamping and the Foreach Loop

This tutorial describes how to use point attributes to influence upstream input nodes, first using the traditional Copy Stamp Node then again using the Foreach Loop nodes as recommended by sidefx. Then it takes an in depth look at the other uses of a Foreach loop: Looping by pieces, by number, and fractals. (77:38)

Lines and Curves

Back to basics, with an explanation of how curves are used in Houdini, covering the Line, Curve, Ends, Curvedraw and add nodes. The these are shown in action when we create a procedural racing track generator (64:25)

Introducing Volumes and VDBs

An introduction to the different types of volumes Houdini can create, and some examples of their
use in procedural geometry creation. (61:27 minutes)

Volumes and VDBs

A guide to the different types of volumes in Houdini, and some basic networks for common uses of volumes in procedural modelling

Attribute Transfer Node

This tutorial looks at the Attribute Transfer Node which passes information from one object to another based on their position in space. It uses a network that places tree roots on a hillside to demonstrate various ways in which attribute transfer can be used to create realistic procedural scenes. (54:00)
