Entagma

Entagma is a collection of resources (tutorials, exmaple scenes, tech notes) that will help you acquire advanced skills in computer graphics. While working on commercial projects we often face unusual tasks that require unconventional techniques to get those jobs done. On Entagma we’d like to share the techniques we’ve been nerding out over and using in production, helping us to create advanced CG animation with a twist.

Tutorials

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 allows you to grow abstract polygonal shapes.

In this tutorial I want to show you how to rebuild one of their creations “Double Mesh” inside Houdini. “Dual Mesh”, the Houdini variant, is an interwoven sculpture made of a Delaunay mesh and its dual, the Voronoi graph.

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. Vein growth has been pretty popular recently. Most setups rely on rather intricate techniques such as Space Colonization. However Ben managed to come up with a neat compact setup that relys purely on Houdini’s built in tools to achieve effects of similar complexity without the need for any coding.

Packing the Torus

Dense packings of objects onto surfaces always look stunning. There are many analytical algorithms out there to compute such a packing. In this video we’ll explore a simulation based approach to achieve a dense packing of particles with varying radius. This is more versatile and easily allows for a nice packing animation.

Easy Soap Film Shader

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 standalone.

A Point Based Growth Solver

Today we build a point base propagation solver from scratch. This is a setup we developed for FMX 2017.

Knitting in 3D | Building a UV Deformer

In this tutorial Manuel shows you one way of modeling a knitted 3D object and a method of making the knit conform to the animated mesh.

Yarnworks: Wire Solver and Constraint Networks in DOPs

Here is a tutorial on a topic I struggled with 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 – this time using Houdini’s wire solver.

Procedural Modeling Of Water Droplets

While putting spheres on a surface is straightforward, this tutorial will teach you how to enhance the realism and quality of the effect by altering the water particles shape to make them more drop like. To achieve this the cross product is used, and explained in a tight theory part.

Live Renderings of Heightfields in RedShift

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.

Quilling: Paper Spiral Mosaic

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.

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

PBD: Dynamic Weave

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.
