Interactive Particles using particlesGpu in #touchdesigner

In this #touchdesigner #tutorial we take a look how we can use webcam and #kinect as a particle source in particlesGpu from the palette for some funky interactivity, and learn some things about particlesGpu along the way. These techniques can be used with any video or pointcloud input! We also incorporate simple motion tracking and audio reactivity.
Let me know if you'd like to see more particlesGpu tutorials from me!

For all those beginners like me who are just following the tutorial and getting nervous as soon as your own output does not match: At 2:26 after adjusting the total number of particles he changes it to life 1 and lifevariance to 0.5 in the particles GPU tab. Loved the tutorial!

🤯Did you hear that explosion? That was the top of my head blowing off! Thank you for sharing this tutorial. This has helped me tremendously!

[MechBullRodeo]

You know it's a good tutorial when you are coming back to it multiple times. I'm on my third rewatch

[arshinazizi]

Wow amazing, thanks for sharing your knowledge 🎉

[carlosserrano]

As always doing amazing tools and sharing with the community!!! appreciate that Dan you rock !!!

Great tutorial! What I find limiting with particlesGpu is that the spawn point tends to be blurry or disappears. But adding another kinect renderer inside the particleGpu component solved it! Also possible to move the camera 360 inside the particlesGpu

Really sick technique, can't wait to mess around with this.

[SQUNTO]

You are the fuckin GOAT!!! Amazing tutorial ty 💚

[taeyangyoo]

Simple and so nice! Thank u so much 💪🏼

[menybliss]

Love your contant! Tnx for sharing with ous your technics.

Nice! I've found that using the cameraViewport OP instead of the Camera OP is nice if you want to be able to smoothly move around the 3D space in real time rather than having the Camera output render after you've moved to the position you want.

one of the best video about that ! Can I ask you where is possible to find the component "MoveDetectDir1" that you show at the minute 17:35? I didn't find on your Patreon.
Thank you man

[puikwanlee]

May i know why my particle box is moving like waves but not moving inside the square box as you in 3:48? Thank you😪

The newer versions of touch designer dont have "Life" option on particlegpu tab so change "Life min" = 1 if the particles arent following your camera properly

[smyrkphace]

Is it possible to give some depth to the first video source method using b&w height field video? I've tried to emit from a displaced mesh but cant get the particles to recognize the uv displacement, it just uses the base mesh. amazing tut! I dont have a kinect so looking for alternative way.

I don't have the grid button that you clicked at the beginning--or the button you dragged the global resolution to on the top bar. I can't figure out how to add buttons there. Can you explain plz?

[MatthieuStephan-mlmx]

Hey, thank you for your wonderful video im new on TouchDesigner and it taught me a lot. And thank you for your toolbar. I can't find your INTERACT_MOVEDETECT in the toolbar. Is it normal? Where can I find it? Is it something you developed only for this video?

[alejandroeduardojareromora]

When I connect the first null to the particlesGPU, inside null you see some colored pixels at the bottom left, not as shown in the tutorial. Do you know what I should do?

[hejira.]

hi, amazing tutorial! Can you teach me how to have a final rectangular output like 1280x720 not a square one? I think the answer is in the ramps grid but i cant fix it

[yilinwu]

Hi! I wanna know why I can't using the space bar after installing this function-store tools ? And thanks for your great tutorial！！
