When we received an E-Mail by Eduard, asking if we had any idea about disco ball packing, we were intrigued. Eduard pointed out that his (apparently very patient) wife manually tiled this sculpture and was wondering if there’s any way to automate it. He also […]

Bubbles Yet Again: Implementing Glassner’s Bubble Triplets in VEX
Bubbles. Again. How thrilling. Wait – before you leave hear me out: Building this setup was one major step for me towards becoming brave enough to tackle implementing my first computer graphics paper. Andrew Glassner wrote a fantastic article about how soap bubble triplets form […]
Holiday Giveaway: Mantra Thinfilm Shader
Happy Holidays! Turns out rendering spherical objects has become our very own tradition by now, so as an addon to Monday’s tut and the question “But can u do it in Mantra?” – Here’s a small present hastily thrown together by yours truly: A VEX […]
Bubbles Again: Simulating Soap Swirls Using FLIP
By now it might have become apparent that Mo might be a bit fixated with soap bubbles and soap films. We covered Minimal Surfaces, soap film shading in Octane and in Redshift. Yet we deliberately omitted one crucial step in rendering nice soap bubbles: Creating […]
Guest Tutorial: Path Solver
We’re thrilled to have Houdini artist supreme Vladyslav Lavrenov for a guest tutorial. And quite a hefty one! Vlad takes us through his reasoning and steps to build a path solver in Houdini to have seemingly random momevements on a grid form a coherent behaviour. […]
Houdini On Mushrooms Pt.2: Point Deform In-Depth: The LinAlg Monster
Be careful what you whish for! 🙂 In this video we’ll be diving into the depths of Houdini’s point deform node. What superficially looks like a trivial task turns out to be a bit more involved than Mo initially hoped for. Brace yourself for some […]
Essential TD Skills: Designing & Implementing Algorithms
A popular misconception we often encounter when answering questions, is the notion that in order to simulate an effect A that looks somewhat similar to another algorithm we built to simulate effect B, all you need to do is tweak a few parameters. While true […]
A Bit Of VEX : Caustics Generator pt. 2 – Extended Features
Building on our last setup, we’re covering rendering out your caustics using COPs, art directing their pattern and making your caustics tileable. Download Project File
A Bit Of VEX : Easy Caustics Generator
Last week we’ve been visited by our good friend Fritz “Frizz the Whizz” Kemmler – a most talented developer. And while pondering some other algorithms, we needed a bit of distraction. So we ended up throwing together this one: A very straightforward and not so […]

Physarum Slime Mold
While Manu and I have been on season break, my twitter stream washed up these mesmerizing, beautiful videos. Turns out they are created by Sage Jenson, a genius digital artists. But not only do they create these fantastic pieces of art, they also go to […]
Analytical Foam
As position based simulation techniques are very fast theses days, it is possible to use them to confrom intersecting spheres to each other, to model foam. Nevertheless there are other possibilities, too.
Polyfolding – Part 2
This is the second part of a two part tutorial. Part one
Polyfolding – Part 1
This is the first part of a two part tutorial. Part two will be available soon. Polyfolding is an interesting effect where you split up an object to individual bands and make them curl up. It can be used to disintegrate an object or make […]
Voronoi Morph
When my office mate Benno asked me to come up with a setup to turn a bunch of hexagons into a voronoi cell pattern, it came to my mind that there is a wide variety of techniques in Houdini to achieve such a transition effect: […]

Nerd Rant: DOPs
Recorded back in October when Mo was cranky due to reasons, Manu decided to discuss his (then) favorite topic when it comes to Houdini: DOPs. Turns out it is not so much Mo’s favorite topic. Watch this nerd rant to see us being cranky and […]
Crochet – Blending between Delaunay and Voronoi
Here at Entagma we love to deal with yarns. This video extends the “yarn-effects” with a crochet approach. Using the delaunay triangulation of an input mesh and its dual diagram, the voronoi mesh, we build a procedural model that uses point color to blend smoothly […]
Isocontours: Importing & Exporting Vectors to/from Houdini
Niklas Rosenstein is with us again! And if Niklas is in the house, chances for some Python code are pretty high. This time we’ll import vectors from Illustrator into Houdini, create an isocontour-effect and export the result back to illustrator.
Low Poly Transform
Blending smoothly between a high-poly mesh and its low-poly representation is a subtle but useful effect. In this tutorial you’ll learn how to create two versions of the same object, one smooth and one facetted, with the exact same topology. This enables you to blend […]
Kitbash Vein Growth Part 2
This time we extend the setup from two weeks ago.
Kitbash Vein Growth Part 1
This tutorial shows you how to create a procedural vein, that is composed of small segments that you drawn by hand. This way the overall look of the vein is art-directable.
Constraint Networks For Rigid Body Simulations
Ever tried having a bunch of instances rotating without intersecting each other? It’s a task we commonly encounter. The solution that usually works for us is a constraint network that’ll pin our instances to their position while still allowing them to rotate freely.
Interference Patterns
While on season break we received quite a few questions. One of those mails pointed us to the amazing work of Loris Cecchini, a sculptor who created (among other stunning artworks) those wave pattern sculptures. At first it didn’t seem clear what’s going on there.
Fakebroidery: Needlework in Houdini
There are very few things more hypnotic than watching an embroidery machine do its work. When watching my wife’s machine working on festive decoration, I thought about how I’d create something similar in Houdini. Turns out it isn’t too complicated once you’ve figured out how […]
Creating A Procedural Snowflake
we have something special for the upcoming holiday season for you: Snowflakes! This was the very first paper I ever implemented in Houdini – what a feeling! I recorded it a while back in summer but then decided to wait until the right season. As […]
Procedural Modeling: Quilling
What popped up as some random images on my pinterest feed turned out to be a whole universe of an art form in itself: Quilling. The art and craft of rolling and shaping paper to form intricate mosaics depicting a wide variety of subjects.
