Guest Course: Creating a Rolling Objects Solver – Part 7
In part seven of our free course on building a rolling object solver, Bastian J. Schiffer extends our solver to take into account random initial rotation and so it works with cubes instead of tubes. Download Project Files
Guest Course: Creating a Rolling Objects Solver – Part 6
In part six of our free course on building a rolling object solver, Bastian J. Schiffer modifies our solver so it works with discs instead of spheres. Download Project Files
Guest Course: Creating a Rolling Objects Solver – Part 5
In part five of our free course on building a rolling object solver, Bastian J. Schiffer modifies our solver to work with POP particles. Download Project Files
Guest Course: Creating a Rolling Objects Solver – Part 3
In part three of our free course on building a rolling object solver, Bastian J. Schiffer covers how to apply our solver to multiple elements at once. Download Project Files
Guest Course: Creating a Rolling Objects Solver – Part 2
In part two of our free course on building a rolling object solver, Bastian J. Schiffer starts building the actual solver. Download Project Files
Guest Course: Creating a Rolling Objects Solver – Part 1
View Full Course Here Please welcome our friend Bastian J. Schiffer who generously agreed not only to do a guest tutorial, but a full seven part course! In this begintermediate course, he is going to take you through the steps necessary to build a solver […]
New In Houdini 19.5 Pt 3: Shallow Water Solver (Plus KarmaXPU)
Mo is going to SIGGRAPH – and he’s running late. So this text admittedly is very brief. In this video we’re gonna (ab)use Houdini’s new shallow water solver to create this abstract streamline animation. Download Project File

Nerd Rant 2.0 – Ep.10: Working Remotely
Suffering through German autumn part two: Manu & Mo finally got the heaters running and aren’t freezing anymore. Fantasizing about working from some warm and sandy beach, they discuss the pitfalls of and solutions for working remotely.

Nerd Rant 2.0 – Ep.8: Dynamic Solvers
Mo dusted off his best shacket (yes, that’s a word!), Manu is donning his best summer shirt – at this point the guys are just trying to mentally escape winter. What better topic than dynamic solvers to get their minds off the muddy weather.

Axiom Solver: Dissolving Logo
In our tradition to being late to the party, we’re giving Matt Puchala’s Axiom solver a spin. It’s a lightweight and fast pyro solver for SideFX Houdini, enabling interactive workflows with smoke or fire simulations. In this video we’re gonna use it together with Houdini’s […]
Mograph Liquids: Controlling FLIP Fluids Via Curve Forces
Been going through a few of Jeff Wagner’s feature presentations from a the last few Houdini releases and stumbled upon a gem which I thought I’d base a setup on: Controlling FLIP fluids using a curve. Throw in a tiny bit of VDB/VEX magic and […]
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. […]
Papers Please – Graph Bundling Pt. 2: Building The Setup
Watch pt. 2 here. In part two of our tutorial on Kernel Density Estimation Graph Bundlig we’re implementing the setup and adapt it to create smooth animations. EDIT: It’s been brought to our attention that there is another neat graph bundling technique based off of […]
Papers Please – Graph Bundling Pt. 1: Theory
Watch pt. 1 here. Let’s spread a bit of joy and dive into VEX and Houdini-SOPs again to implement a really neat technique from a french/dutch paper covering graph bundling. While graph bundling is usually found in network analysis or geovisualization, we’re gonna adapt the […]
Quicktip: Double Pendulum In Vellum
Another one of those physics/math/CG tropes is the double pendulum: Take a standard pendulum (one arm that can rotate around one or more axis) and attach another pundulum to its end. The fascination for this contraption comes from the fact that it behaves extremely different […]
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 […]
Live Rendering of Heightfields in RS
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, […]
Yarnworks: Wire Solver and Constraint Networks in DOPs
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 […]
VEX in Houdini: Diffusion Limited Aggregation (Plus Rendering in Mantra & Redshift)
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 […]
Guest Tutorial: Yader – Poly Garden
We’re happy to present to you another special guest on Entagma – this time it’s Yader (who some of you might know through his great Cinema 4D tutorials). In his tutorial he’s gonna shed some light on how he built his Poly Garden setup that […]
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 […]
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.
VEX in Houdini: Strange Attractors
In this tutorial we’ll focus on two extremely powerful tools inside of Houdini: VEX and solvers. VEX is houdini’s scripting language. It is multithreaded (which means fast) and based on C (which means it’s also similar to Processing, Arduino, Java, Javascript, C++ and C#).
