Live-Rendering-Of-Heightfields-In-Redshift3D

Heightfields are a nice addition to Houdini 16 for environment work. They more or less replicate the functionality of programs like Worldmachine. In today’s tutorial Manuel shows you how to create a terrain from scratch in Houdini and how to render it directly in Redshift3D, without baking out textures manually.

VEX in Houdini: Diffusion Limited Aggregation (Plus Rendering in Mantra & Redshift)

DLA.Still001

When we saw Andy Lomas’ “Aggregation” series a few years back we were struck. How could you generate those intricate particle sculptures? The series’ title hinted at one possible solution: Diffusion limited aggregation or DLA. In this tutorial we’ll build a basic DLA setup using VEX and volumes. Also we’ll talk a bit about rendering our result in Mantra and Redshift.

Quick VDB Clouds

After being asked how to create clouds for rendering in Octane (or any other Engine that supports VDBs) we dove into that topic a bit and the quickest way we found was to use the cloud tools that Houdini provides.

One of the great things about the Houdini community is that we’re always confronted with clever questions and with clever answers too. “How do I color strands using an image’s color palette?” was the comment on Vimeo that led to this setup. Yet when talking about coloring polylines we also need to discuss rendering them.

Differential Mesh Growth

As some of you already found out, it is quite possible to set up differential growth not only on a line but also on a mesh. This tutorial goes into the details of doing exactly that while allowing for some degree of art-directability (is that even a word?) of the growth patterns.

This is a classic effect in Houdini. I stumbled upon it over at Odforce. As you will see from that thread there are many elaborate ways of achieving this kind of growing curve. However we’re gonna build a very simple version which yet offers a nice way of controlling growth by passing along values from a noise field. Hope you have fun!

Loops & Subdivisions

Rrecently two projects caught my eye – one is called “Subdivisions” by Adam Heslop, the other one is the new SideFX Ident by Simon Holmedal. Both employ (as far as I can guess) a technique to subdivide a selected part of a mesh over and over. In this video we’re gonna set up a simple version of a similar algorithm. Also included is a neat trick how to efficiently render splines in Mantra.
