Special Guest Tutorial: Shortest Path Growth

Say hi to our very good friend Ben Watts of BW Design. We’re thrilled to have him on Entagma for a guest tutorial showing his newest technique for vein growth in Houdini without any VEX.

Naive Path Finding

This one is a rather brute force approach for a problem we had to solve on a recent job: Finding a path through a bunch of obstacles. Admittedly what we implement here isn’t a very sophisticated algorithm, but its power lies in its simplicity: It […]

Custom Particle System in VEX

Dobromir of Inlifethrill Designs asked us how we’d go about recreating this. And as I’m quite untalented with Houdini’s particle system, I turned to VEX to create this custom particle system in which individual particles attract each other.

VEX: Space Filling Curves (aka “that Windows 95 Screensaver”)

Another question that we’ve been asked is how to rebuild a setup similar to that infamous screensaver that slowly filled your display with a maze of pipes. Among various approaches (including some L-System experiments) the most naive setup won. Of course.

VEX / VOPs Basics: PCFind

One of the top three questions we’ve been asked during season one was “How does PCFind work?!” and indeed the question is important as so many setups rely on the ability to find close points.

Colored Trails (Point Advection & Rendering)

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 […]

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 […]

Differential Line Growth

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 […]

Loops & Subdivisions

Recently 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 […]

Fractal Ornaments

It often occurs to me that I need to look up certain functions in Houdini. One of those things that I constantly struggle with are For-Loops. So as a reminder to me and to you – here’s a tutorial about their use. We’re gonna build […]

Quicktip: Abstract Shapes

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 […]

Houdini: True 3D Reaction Diffusion

You might have seen this effect more frequently during the last months: Those growing organic blobs that cover a surface in intricate Patterns (sometimes resembling the texture found in a Keith Haring painting). These patterns are the result of a process called Reaction Diffusion.

Creating Geometry With Python In C4D

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 […]

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 […]

Creating Geometry With VEX

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 […]
