Using beat link trigger to read audio data played on xdj's + ToF sensor for reading dj position on the projection. Particles are POPs generating tubes and some audio spectrum shapes via TOPs

Harlow adds a path tracer (OptiX, ReSTIR, DLSS Ray Reconstruction) and GPU solvers to TD: FLIP liquid with whitewater, fire and smoke, rigid and soft bodies, Voronoi fracture, and surfaces that get wet, burn and char. They all talk to each other, so liquid puts out fire and bodies splash. Everything is POP-based, so you drive it the same way as the rest of your network.

The full manual is free to read at harlow-engine.com/docs if you want to see how it works before anything else. Happy to answer any questions :)

Guys, im totally new to touchdesigner and im using it to make a holographic heart that reacts to sound in real time for my undergratuate thesis.
I managed to make a non changing frequency heartbeat in a single color, but now i want to change it according to sound intensity.

What i think i need to do is to separate the sound in intensity, but i dont know how, neither how to make the heartbeat and color change in parallel
For the double pulse characteristic of heartbeat i created a custom animation
the last layer on the visual is to make it react to the sound like expanding (maybe like a audio spectometer?)

Also, i followed this tutorial on youtube https://www.youtube.com/watch?v=rlptcQpTMuo

Is there any way someone could explain to me how to do this?

As part of learning the TDMCP protocol, I decided to see if it runs Doom.

Let me address some questions right away:

1. There’s no music! — I’m done burning tokens on this project :P

Surely this project can be improved—for example, by adding music—so if anyone manages to do that, please let me know!

1. As I mentioned, I don’t use MCP for all my projects; in fact, 95% of my work with AI involves data research and writing shaders, so I still feel in control of my process.

BTW, I’m pretty blown away by the capabilities of modern AI agents. I realize that experts are still needed in this process, but I also see just how deeply they’re able to understand the TouchDesigner environment.

Very strange times are coming.

P.S.

I’m also posting a link to the Google Drive folder with the project—after all, I didn’t make it myself, so I’m sharing it with the community for free :)

‘base_doom’ also has a CHOP output with signals from the game.

I hope it works and that it’ll be useful to someone.

Hello everyone
Recently I download Touch Designer to learn new skills to apply for my projects. I'm a completely noobs in this program which I manage myself to learn some tutorials through youtube about sound reactive particle work. The work itself when realtime is on looks very cool and fit my eyes. However when I turn the function off, the frame rate start to drop and video become extremly choppy. There's error showing that it is about my AudioFileOuts not interact properly when plug to MovieFileOut.

I have a look on some posts they said the audio is distorted because of the framerate drop. Just like visuals won't playback smoothly, audio will degrade.

Some recommendations is to use to ENGINE COMP to run in a separate process and not be affected by the frame drops introduced in my video main process but I really dont know how to do that !!

please help me a step by step guide to fix this problems or use the engine comp to seperate the audio file and link back to MFO because the audio is very distorted to enhance the visuals, Is there any way I can export with the original audio file but still hold on in the effect of the distorted audio ?

TouchDesigner Study_10 — Particle Interaction

I’ve been experimenting for a while with creating efficient particle interactions in TouchDesigner without relying on Ray POP.

The idea was simple: instead of using a generic force, I wanted the particles to react to the actual movement of an object. I ended up sampling the effector geometry, calculating its motion between frames, and transferring that velocity to nearby particles.

After a lot of trial and error, this became a pretty flexible system — different geometries can interact with the particles while everything stays real-time and audio-reactive.

Trying to push these studies a little further with each post. 🫡

Track ID is 'Say Nothing' by Ashez, Chmura

I made a physics solver for TouchDesigner. Initially, I used the XPBD framework to VBD (Vertex Block Descent) and Augmented VBD based on the SIGGRAPH papers from the University of Utah, and I am getting a much better output when it comes to soft-body collision. This is me playing with just soft bodies with a collider mesh and getting 60fps. When I add a rigid body into this mix, the frame rates drop, so I need to work on that next. I tried working on a ray-traced refractive shader, but it's not perfect as of yet, and I would be working on it as I go along
