In this quick tutorial I show how to setup a particle attractor and control it with your hand in realtime. There was more to this video but it corrupted so it ends rather abruptly.

Thank you for this tutorial! The only tutorial that has taught me how to use the Kinect in a way that I want :)

Hi! Thats really nice vid. But is possible to control attraction by two different users (like user one is on the left and user 2 is on the right side of the screen and particles are attracted depending on the Z position of users ?)

if you wanted to create a mesh that would stick to users as they walked by how would you do that?

Great tutorial! Was wondering, how do you add another set of "attractor" when there is more than 2 people interacting with the kinect? So that the emitter emits particles according to the number of people on screen. Kindly advise

@VisualesqueVideo 6 жыл бұрын

Jin Han Ngoh you can have multiple sops merge together with the merge sop and then plug that into the particle sop

I've followed along exactly but when i attach the attractor sphere into the input labelled Surface attractors on the particle sop it doesn't cause the particles to turn back in like it does when you do it. I can't figure out what i'm doing wrong. Can anybody help?

I have a question too, so here I'm using kinect v2 , this is the only video on internet that shows u that so far, well done. At 4.41m when you switch the near depth on, here is cannot switch it even with face track on, I tried turning the kinect 2 node into a version 1 of the kinect and that works but my problem is I cannot see all these bars inside the nods with values for each arm , leg... neither if i select version 2, what am I doing wrong? thx

Amazing intro into particles and at attractors. Exactly what I was looking for. Any suggestions on improving the performance? I created 3 attractors and now my FPS is hovering around measly 10, despite having 2GB graphics card (I know it's not a lot, but should suffice for the simple particle system here).

@iljapanic 5 жыл бұрын

Setting up a default 1 frame / SFPS helped a little bit, but the FPS is still miserably low (25-ish)

@VisualesqueVideo 5 жыл бұрын

@@iljapanic Particles in TouchDesigner run on the CPU so if you have a lot of particles they'll be slow as it's the CPU that's taking the hit. If you go to the palette you can find a component under tools called ParticlesGPU. This is a GPU version of the Particle SOP. You might be able to use that although it isn't as flexible as the particle SOP.

@iljapanic 5 жыл бұрын

@@VisualesqueVideo Thanks a lot for such a quick reply! Found the Particles GPU component, looks smoother at the first sight. Any pointers for how to attach attractors to it? There is only a TOP input available by default.

Thank you so much for this tutorial. But for some reason even I set my Hardware version as version 1 for Kinect, the sensor does not change into kinetic 1... can you help me to solve this issue?

@RichardBurnsanims 6 жыл бұрын

Sangdae Park if it's not switching that sounds like a bug. Make sure you have the correct kinect drivers installed and if you have I'd report this as a bug on the derivative forum

@jordanborges2370 6 жыл бұрын

Is there a way to have the second sphere avoid the first sphere, instead of attracting it? I am just wondering if that would be a way to push objects?

@VisualesqueVideo 6 жыл бұрын

For pushing you could use the particle systems collision object (2nd input of the particle SOP) and set the particle SOPs hit behaviour to bounce on contact (this is on the particle SOPs limit page) and this would for example make your hand an affector. Another option would be to use the third input and plug a metaball followed by a force sop into that to act on the system. This is more useful for disruptive effects such as vortices etc though.

Laura Iturralde it might be that you haven't set the render flag or the display flag, these are the two circles on the bottom right of the operator

Hi, great tutorial so far, but how do you change the Background colour to black on the render window? Mine is a transparent checker board effect. Thanks.

@RichardBurnsanims 9 жыл бұрын

Hi Graham, This is in the preferences. edit menu > preferences > TOPs > viewer background. You can also just composite the visual over a Constant TOP and set it to black.

@MrThebigcheese123 9 жыл бұрын

Richard Burns Thanks man, much appreciated! Also, could you tell me how to full screen that window for a projector? If its not too much to ask :D Not sure how i could run it full screen on a separate monitor, also would this cut back on the physics and allow room for more FPS? Thanks.

@RichardBurnsanims 9 жыл бұрын

You can use the window COMP to do this. You drag the TOP that you want to send out onto the operator parameter of the window and then set its size to fill location. Set borders to off and monitor to the monitor Id (probably 1) then when you toggle open on it will open up the window on the second screen

@MrThebigcheese123 9 жыл бұрын

Richard Burns Hmmmm, i am looking to have the who display on the second monitor, that will be the interaction screen, black background with the animated interaction on it, bit like projection mapping, I hope this software can do it :( Just tried what you suggested and when i change to monitor 2, nothing happens no display pops up on my other screen, thanks.

@MrThebigcheese123 9 жыл бұрын

Richard Burns All sorted now! Bar the particles leave a grey stencil outline on the secondary monitor, once opened on the second monitor, the background is a solid black, but upon interaction it starts generating this grey mess, odd huh? Probably a software fault. Thanks though! :D

You could use the mouse in CHOP or the joystick CHOP if you have a game controller as a replacement for the kinect CHOP.
