In this tutorial we are gonna work with a shape imported with a Kinect. After a little preparation of the input image form the Kinect, we will see how to apply a burning effect and a gradient of colors to it. Moreover, we will learn how to apply a little effect to the smoke of our burning shape.
What we will use:
- a couple of TOPs
- Flow emitter COMP and flow TOP
- LFO (CHOPs) and how to apply them to a TOP
- Ramp TOP to apply the gradients we want to a burning shape

yours tutorials are very good, well explained! more kinect stuff please, thanks for sharing.
Thanks for your support. I will publish more videos soon. In which topic would you be interested?
@@maurizioorlando97531 i woul say more interactions with kinect / new fonctions from last updates of TD
@@kolektor32 thanks for your inputs. I'll work on that.
@@maurizioorlando97531 in fact i m learning TD to produce 3D animations / presentation for my company, i work in medical field looking to produce those kind of stuff like on this page : www.germitec.com/en/ maybe we could learn how to design a coronavirus animation like stuff we see all day on tv etc lol, what you think? ahah

You need the play around with Shape Threshold in Flow Emitter a bit to show the human figure on flow for TD 2022.32 and later
i've moved whole shape slider in every possible place and i still get square results? any idea
Amazing! Thank you SO MUCH for sharing
Bella maurizio che nn diventi un vizio!! Grandeee!!
well done Maurizio, nice tutorial, thanks for sharing!!
Thank you Fausto!
@Maurizio Orlando, Hey ive been following tutorial, but once i change from Sphere to Shape TOP, it doesnt follow shape but whole square black background around shape? any idea, could it be versions related?
yes it could be an issue with the version. this tutorial is a bit dated indeed. however you should still be able to get the same outcome somehow. let me know if you can't find out how to make it work and i'll have a look to how to get it work with a newer version.
really a good tuto !
Thank you!
tremendo maquina
Thanks that was really informative, just learning TD.
You're welcome! Hope it was helpful for you!
Yes very clear, @@maurizioorlando97531 I like short simple tutorials like this so I can add block by block to learning TD.
@@maurizioorlando97531 Thank you very much!I look forward to your other tutorials on this
@@user-dr9yi6wm4p thanks! Happy you appreciated! :)
@@maurizioorlando97531 Hello, I had trouble using touchdesinger, I got a humanoid trace Chop through kinect, I want to know how can I put a force on this trace so that it can collide with surrounding particles, thank you very much.
Very cool. Thank you!
You're welcome!
which kinect were you using? I am beginner about kinect, so please let me know any recommend knowledge about kinect :)))
nice!
Do i need to have the kinect device to make this project? Or i can just use my laptop camera to detect my movements?
you can do that with your laptop. you might need some suitable lighting and then i guess you'll need to play around with the threshold parameter in order to detect a shape. once you get that you just use that as the starting point to then burn your shape.
@@maurizioorlando97531 ouh i see..thanks for replying 🙏🏻✨
Hi Maurizio! When I have my kinect TOP, and I select Player Index, nothing is being shown in the preview, or when I try to record with the movie file out. It works in the depth image option, but not player index. Any idea as to why?
when you set player index in the kinect top the image shown in the operator is black. however if you start to move (like waving hands and walking left & right) in front of the sensor at the right distance (like 3-5m from the kinect), a dark grey silhouette should appear in the preview.
Also, the movie file out will show something in the preview just when the record button is toggled 'on' otherwise the operator won't show and record anything.
If you still have troubles with that you could record your movements outside Touchdesigner and especially in Kinect studio and then play the video there. In this way Touchdesigner will recognise that video as the kinect TOP input.
@@maurizioorlando97531 Ahhh yes, I realize that I was too close to the camera, thank you for your fast reply. The tutorial works great now!
@@anider great! Glad to hear that! If you have any requests for new tutorials just let me know!
Hi Maurizio, I'm new to TD. I assume it's possible to substitute the camera feed with a video or image and have the smoke take shape from that, right? What I'm trying to do is make Chinese characters become visible in the smoke and then dissipate into the air.
Same, I have a video input but it doesn't seem to read the "null1" output as a shape TOP. Do I somehow need to convert my video into a shape? I have no clue what I"m doing
Hey sorry for the late reply. You should be able to use other inputs. However I believe you should use a thresholded image of your input to be able to achieve your goal.

How can I get ENG - Flow emitter - Burning shape (Kinect) since I could not get this pluging for 099 to.
Hi! You need to install the experimental build of Touchdesigner to use the flow emitter.
Another awesome tutorial! I am still new to TD. I am still trying to figure out how to use all these cool things. But what is the point of doing all this just to see it in our project GUI? I have not used the 'perform mode' window yet. Do we output it to some other screen or something?
What are some things you can do once this project is baked? Like for shows, or live art? I don't get that part yet. What can we do with the Smoke Guy if it is in a window of an operator, and what are ways we can apply it to something interactive?
Hello! These are all great questions but they mostly refer to your artistic intentions which is not the purpose of this short tutorial.
This video is just for showing how to use the flow emitter operator and something you can visually achieve with it.
Maybe what you need to find is a concept and then finding the techniques you need to realise that concept.
@@maurizioorlando97531 That is probably true, and thanks for your advice. I am definitely a fan of yours, and I'm curious about if you use this for artistic purposes yourself?
@@maurizioorlando97531 haha nevermind. I died at Nvidia. I didn't know to do this you needed an Nvidia graphics card until I got to the Nvidia Flow operator =/ Thanks, anyway.
@@THEcucufate yes I do use it for artistic purposes. I am a circus performer and I create my own multimedia scenography for the Led screens with Touchdesigner. Moreover I use kinect for some experimental performances (for theaters) and I also try to transform the artistic concepts of the directors in interactive numbers. Finally I am using Touchdesigner for creating my own 40 minute performance but at the moment it is still at a working in progress stage and I am researching new possibilities to integrate circus and interactivity.
@maurizio are you using kinect v1 or v2?
V2
can this be done with a live kinect feed?
Yes sure. Check the whole video out. At the end of the video I show how to do that
@@maurizioorlando97531 thanks for this! I made a slightly different version but greatly enjoyed!!
@@kengray1860 thanks for your words. It would be nice to see what you came up with :)
Can you recommend what type kinect you use [ from xbox ] version 1 or two ?
I use the Kinect V2 and for a lot of TD projects I'd recommend that. However if you need to 3d scan then go for the V1.
Maurizio Orlando thank you ... im new in TD can you give me short reviews each version of kinect [ v 1 and 2 ] please ..
@UCPpNu4ADAS0ALjB4iBjqcDQ check this out: zugara.com/how-does-the-kinect-2-compare-to-the-kinect-1 . In general kinect V2 is more precise in terms of skeleton tracking, color camera and depth camera resolution. However, for 3d scans seems that there are more software working with the v1 and remember that tracking is still possible with v1. Also the prices for the V2s are higher than the v1. Depends what you need to do with the kinect.
I dont have those options in my list. is yours a pro license?
Hello! You don't need the pro license. You need to install an experimental version for using the Nvidia flow. Let me know if you have still problems.
@@maurizioorlando97531 hi friends, i dont have the nvidia flow in my TOP list, it only works with nvidea GPUs?
@@jodkbarberan1364 yes just with nvidia GPUs
can i use kinect 360for this?
I have used kinect V2 for this. Not sure about the v1 but I think it should work.
nice tutorial! how can I give a different color for each person that enters the scene?
Hello Daniele! I have already thought about it but not tried it yet! The only thing I believe it can work looks more tricky than a just smooth workflow: once you isolated each person, you can build up a different Flow emitter system related to each person. Every Flow emitter should then contain a different color ramp applied to the silhouette. Of course this will be very demanding in terms of performance for your graphic card. in this case you might turn up the Sim Size in the page Setup of the Flow emitter TOP (choose 32 for all of the parameters). This will make the simulation less accurate but less intensive for the processor.
@@maurizioorlando97531 thx a lot for the fast reply! I don't think that my graphic card can handle multiple flow emitter.
@@danielemaselli2859 give the Sim size trick a try! ;)
@@maurizioorlando97531 Hey Maurizo, how would you go about isolating each person using a player index? I noticed in the derivative docs for Kinect TOP is states that there is a pixel value in increments of 0.1 for each player number. I just don't understand how I would go about using this value to isolate each player. A tutorial on this would be amazing and extremely useful. Anyway keep up the great work!
@@SeeRjED definitely. I'll work on this as soon as I can.
can i try this using v1m
never tried with v1 but it should work. if your device is recognised you should not have problem to track the player index
