Quicktip: Double Pendulum In Vellum

comments 4

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 depending on its initial condition.

Creating A Procedural Snowflake

comments 14

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 the first snow is hitting the Munich area I guess it is about time to release the tut 🙂

Live Rendering of Heightfields in RS

comments 10

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, without baking out textures manually.

VEX in Houdini: Diffusion Limited Aggregation (Plus Rendering in Mantra & Redshift)

comments 17

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 VEX and volumes. Also we’ll talk a bit about rendering our result in Mantra and Redshift.

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 allows you to grow abstract polygonal shapes.

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 even a word?) of the growth patterns.

Houdini: True 3D Reaction Diffusion

comments 40

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#).
