"Rotational Force" - Tooll3 Tutorial on how to create your own HLSL Compute Shader Particle Force

Tooll3 is a node-based, opensource, realtime animation software for Windows based on C#/.Net and HLSL. In this video I show you how to create your own HLSL compute shader particle force in Tooll3 and the complete workflow on how to set up the operator interface, create parameters and dropdowns with defaults and useful input ranges, re-order parameters, rename inputs, sort out the compute shader input buffer slots, get useful error messages, write documentation, create examples and presets and also guide you through the code and the simple example scene I created. I talk a bit about GPU threading and [numthreads] and I found this video very helpful to understand the inner workings of GPUs and compute shaders:    • Compute Shaders || Lou Kramer || AMD   Tooll3 is open source and ATM available on Windows only (although one user reported having it running on Linux in a Bottle). You should have a decent GPU for good performance. This video was created with Tooll3 3.9.2. In the meantime, 3.9.3 is available and highly recommended, especially for the new GUI editor that makes reordering parameters and renaming them much easier: Download Tooll3 here: https://tooll.io Installation docs are here: https://github.com/tooll3/t3/wiki/hel... I highly recommend joining the Tooll3 Discord for any questions you may have:   / discord   I did several animations with the force already. This is the one I mention in the tutorial, using only factory forces:    • "Radi(c)al Force"   And two more where I also use other custom forces I created:    • "The Vortex"      • "The Door into Summer"   Big thanks to the father of Tooll3 "Pixtur" and everybody in the fantastic Tooll3 community on Discord!
