This time we extend the setup from two weeks ago.
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.
S Due to the fact that the SDF is defined in 3D space the setup can easily be animated, too, to create some fake water ripples. Download Project File
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.
Yeeeha! We are back. To start off season three in a gentle way, let’s look at an easy setup to produce intricate eye candy. Also watch Mo burning his fingers on microwaved ink. The pleasures of real world experiments.
Curve framing is important for a lot of things, like trajectories, creating geometry from curves or aligning copied geometry to curves. In this tutorial Manuel implements the parallel transport algorithm that transports an initial normal vector along a curve to create a smoothly varying frame. […]
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 […]
Today it’s about dynamically generating a piece of woven fabric. Manuel explains how to write a VEX wrangle in the DOP context to generate connecting yarns in every frame.
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 […]

If you want to make your product appear nice and fresh in your TV commercial, chances are that you’ll put water droplets on it. This effect is very popular in advertising. In todays installment of the Entagma tutorial stream, Manuel shows you how to procedurally […]
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.
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, […]
To complement our PBD Wire Setup, here is a tutorial on a topic I’ve personally been struggling a lot when I first tried wrapping my head around constraint networks. Similar to what we’ve been doing in PBDs, we’re gonna build a network of interconnecting wires […]
You might not be aware of the fact that you most likely have been using the algorithm we’re discussing here – at least if you’ve ever worked in 3D. Quadtrees (and their relatives, KD-Trees and Octrees) are used to accelerate point queries (ever used pcfind() […]
Branching growth is fascinating as it has a lot of hidden structure to it and is very intricate. Many methods have been proposed over the years to model branching structures, like trees. One algorithm that is particularly beautiful and simple is the “Space Colonization” algorithm, […]
The past decade has seen a wealth of data visualization elements in UI design, movie sets and motion graphics. When it comes to creating these elements you’re left with two approaches: faking it vs. the real thing. In this quicktip we’re doing the real thing […]
Finally we venture into new territory in Houdini: Python! With the help of our very talented friend Niklas Rosenstein we’ll have a look at how to import actual satellite data from ESA’s Gaia mission into Houdini and use it to render our very own star […]
Knitting in 3D is quite popular these days. Although it is not too hard to achieve, building a knitting setup presents some challenges to the TD. In this tutorial Manuel shows you one way of modeling a knitted 3D object and a method of making […]
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 […]
By far the most frequent question we received after our minimal surfaces tutorial was “how do you build that bubble shader?”. The wait is over – in this tutorial we’ll go over how to build a plausible soap film shader in Houdini’s Mantra and Octane […]
This episode we managed to get away from our workstations and head outside to Munich’s beautiful olympic park. There we found some prime examples of the shapes soap films form when they evolve between metal wires.
When testing out a new render engine (or any tool that can do rendering), one of the typical objects I try to get a decent image of is a quartz crystal. In order to get that right, a rendering needs to contain effects such as […]
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.
We get the question “why are you doing that setup this particular way?” reather often. As with most setups in Houdini there are many ways of building it. In this tutorial we’d like to go over different approaches of solving a very basic problem: Scattering […]
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 […]
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.
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.
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.
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 […]
We’ve been visiting Ars Electronica this weekend. It was amazing. Such a weird and wonderful collection of modern nerd art presented in an astonishingly creepy environment. (Think nuclear shelter underneath an abandoned logistics center). What that meant however is that there was only very little […]
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 […]
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 […]
In this quickie we’ll go over how to turn standard voronoi cells into something alittle bit more organic. We’re going to use a combination of standard SOPs to quickly build a versatile procedural setup which allows you to create a plethora of different patterns.
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 […]
The Mandelbrot set – the mythical King of fractals. The one that started the whole fractal craze in the 80s and 90s. In this video we’ll implement not only a classic Mandelbrot set that will yield the omnipresent image of that weirdish ridged shape, but […]
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 […]
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 […]
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.
This short tutorial ist inspired by the amazing work of deskriptiv. Seriously one of the most inspiring artist collectives I’ve come across in the last year. What (in my opinion) is being done here is a curl noise flow around a given surface that is […]
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 […]
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 […]
