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 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.
@@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.
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
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 ?)
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?
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.
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.
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.
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.
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
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.
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
hi! Igo into the geometry and make the change thorus>sphere with particles, but when i go to the up level everithing inside the "geometry" is dissapear. Any idea? Thanks!

Thank you for this tutorial! The only tutorial that has taught me how to use the Kinect in a way that I want :)
This is a great workflow for seeing/calibrating input values. So helpful! Thank you.
thank you so much for sharing your expertise

same problem here. even if your comment is 2 years old.
Hello, amazing tutorial, like black magic. thx a lot
Man, this is dope
Some good info here, Thanks!

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

ha its fine man, i was just too close to camera for it to track skeleton, everything just appeared.
this saved me thanks!!
How about group interaction? We do it manually for each person?
Great tutorial!

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

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?

Kinect 2 doesn't like my laptop half of time also. - Desktop works fine.
great tute man!

if you wanted to create a mesh that would stick to users as they walked by how would you do that?
Can it be applied to lip motion?
Hi, i'm stucked. The expression 0.5/$FPS is not working, is the same use root.time.rate ?
It is yes. It's the old receipt variable... I'd recommend using python these days
@@VisualesqueVideo thank you so much for your time and the quickly reply to my question🙏🙏 New subscriber.
great thanks for that!!
hey is there a next video i mean how to deploy it?
th-cam.com/video/Jh18yHfYT0I/w-d-xo.html have a look at this video for getting the visual to the output. It shows how to setup a window
hi! Igo into the geometry and make the change thorus>sphere with particles, but when i go to the up level everithing inside the "geometry" is dissapear. Any idea? Thanks!
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
it works!!! thanks!!!
gracias
Hi! I wanted to know if this works with Kinect for Xbox. I have the power adapter.
Thank you :)
churrito ....that’s the whole point of the video moron
thank you
hi, if I don´t have a Kinect, how can I achieve the same result?
You could use the mouse in CHOP or the joystick CHOP if you have a game controller as a replacement for the kinect CHOP.
do you have any online course?
student cannot use kinect...pity
Is this an issue with the tutorial or are you just commenting on something vague? Can I help?
Some good info here, Thanks!
