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!

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.

After publishing the VDB denting tutorial, we received some questions regarding how we created the geometry used in the preview rendering for that tutorial. In this quicktip we’ll show you how to create the organic shapes we used when testing that setup. It’s a neat combination of geometry and VDBs.

Hi people from the internet. After posting my geometry creation tutorial for Houdini, people approached me with the question, if such a plexus effect is possible in Cinema 4D, too. And I said no, not without plugins. But after thinking about it for a little while, I found a solution to do this with Cinema4D off-the-shelf tools. I’m using the ParticlePassAB node to find the closest points and Python to create the geometry. So if […]

Houdini: Boolean Volume Denting

When I saw this tutorial on Greyscalegorilla, it occurred to me that although I liked the results a lot the process of sculpting and posemorphing would be a bit too unflexible for my needs. And of course it would also be too tedious for a lazy nerd like me to manually sculpt dents. I was already trying to figure out a procedural approach for this dented look.

Creating Geometry With VEX

CreateGeometry02_layout02_02

Did you ever wonder how to create polygons and polylines through code in Houdini. It’s a straigtforward concept. But you have to know some things about the way Houdini organizes and stores geometry in memory. In this tutorial Manuel will walk you through the process of creating geometry with VEX in a wrangle. After some theory he’ll show you how to generate a closed polygon. Then you’ll learn how to connect neighbouring points with polylines […]
