WS23 -TD 13 – Past the Palette: Extending the ParticlesGPU for Custom Uses

Image by Lake Heckaman

Recording of January 24th 2024 in English Language
Recordings are available for one year after purchase.

In this workshop, you will dive into the ParticlesGPU component in TouchDesigner’s palette and build a robust understanding of its inner workings, so that you can customize it for virtually any use case you might come across.

First we will dissect the existing GLSL shader and peel back some of the complexity, before moving on to our first practical examples like building a flow field particle system to visualize velocity maps (including a Fluid Simulation).

We will then explore adding your own customized attractors and interactions to a system and using hierarchies of particle systems to achieve interesting, complex behaviors.

Finally, participants in this workshop will build a lightweight and modular rendering pipeline purpose-built for particles to achieve bright, beautiful renders of their system.


If you are new to shaders, we recommend taking this introduction module by VanTa first.
