In Part 4, we use the Autonomous Agent component we created in Part 1, adding these agents as […]

Premium Patreon Exclusive: Fluid Simulation TouchDesigner .tox

Dropping my fluid sim .tox for my premium subscribers – in this video I give a walkthrough of the simulation (dont worry, we won’t be doing any coding) and its major parts. Then I demo the COMP I have created to use it in my projects, reviewing all inputs, outputs, and parameters. Finally I run […]

Pixel Sorting in TouchDesigner Part 2: Dynamic Anisotropic Detail

Bring your pixel sorting to life with multi-layered dynamics! In this tutorial we build on the basic pixel sorting component from last time, adding texture and details that vary from place to place across the image. We also see examples of using Python list comprehension and Python conditionals inline to control operator parameters. Project files […]

Terrain Particle System – Part 3: EXR Files and Procedural Terrain in Houdini

Learn to import EXR files (common format for heightmaps/terrain data) and use them to drive particle systems. Build your own using detailed and physically realistic terrain models in a few clicks using a free Houdini Apprentice license (its easy, I promise). Or just use the EXR file I provide to follow along as we import […]

Part 1: Procedural Terrain Generation in TouchDesigner

Learn how to create procedural terrain heightmaps based on the topology of real ranges, a technique ported from Texturing and Modeling: A Procedural Approach (which I highly recommend for those looking to learn). Over this set of tutorials I will build on this technique and others to create an interactive particle system using various methods […]

Realtime Caustics in TouchDesigner with Easy GLSL

Caustics form from light refracted through a transparent medium (like the pretty patterns that form on the bottom of a swimming pool). This tutorial will outline the physics involved and show you how to create this effect in TouchDesigner using only a handful of lines of GLSL code. Resources: Ray / Plane intersection: https://www.scratchapixel.com/lessons/3d-basic-rendering/minimal-ray-tracer-rendering-simple-shapes/ray-plane-and-ray-disk-intersection.html Caustics […]

Custom Keyboard Shortcuts in TouchDesigner with the UI Class

The motivation: It is way too hard to toggle display background TOPs on/off, which was an annoying workflow issue for a long time. With this simple tool, we can create a keyboard shortcut to quickly solve this issue (and many others!) As Derivative is fond of pointing out, TouchDesigner is built with TouchDesigner, which means […]
