Render Pick without MultiTouchInDAT in TouchDesigner
Use any sort of interaction data for render picking, without the MultiTouchDAT! I will show you how to use any chop-based data as a source for render picking, applying these interactions to alter a point cloud instance-by-instance! We will scale, move and recolor instances with ease.
If you dont see the point cloud on file open, press ctrl-` to reset the system. I have also included a link to the HDR image I used for env map, and attached the substance file here as well. You might need to download these and update the paths for the scene to render properly.

Thank you, this is excellent stuff
Thanks a lot for this tutorial!
How do you download from Lumalabs? It doesn't allow the option
it needs to be a capture you created on your account, then you can download it from their web app
@@water__shed I understand, I thought I could download models from featured gallery Thanks ;)
Does this work for videos as input?
have you tried it?
can we change the moving points to Kinect gesture interaction or webcam interaction?
+ 1
yes, that is the whole point of this tutorial. you just need to format your kinect data (or mediapipe data with webcam) to the same [u, v, select] format we used in the tutorial, then wire into the render pick dat
@@water__shed cool thanks!
I have the question actually about the video instead of image. i want video contantly updating with the effect instead of pressing keyboard constantly. How to make the video update in real time with effect?

Thank you so much! I did realise about SOP Filein operator later. But i will check your reference for sure,
How can we replace boxes with any custom imported geometry instances? Like 3D butterflies, flowers, whatever... i guess it's not just changing a SOP sphere to a custom 3D TOP?
you can use the filein SOP to load custom geometry (.usd or alembic works best, or bhclassic from houdini). but it will likely require some decent work to get them working, such as custom vertex shaders etc to animate your butterfly
you can check out david braun's boids tutorial for a good example, he uses a 3d model of a bird for a flocking simulation
Hey, Can we find the colored visualization part (shown in the beginning) on your pathreon file? Thanks for the tutorial!
Is it possible to upload a link to this GLSL code?

hey, I am having trouble with getting the video from my phone to actually play in touchdesigner, the video input only gets one frame and stops do you have any work-arounds for this?
pretty hard to say wihtout more info - check your internet connection / bandwidth is there (try over USB instead of wifi, see if this helps). Sounds like the connection might be bad. Also make sure TD is not paused and your laptop is powered, not on battery
very cool!! 🥰
Bro amazing work!!
Any luck on MacOS anyone?? Can't seem to get it to work
Hi, Thank you for the video. For some reason I am not able to upload a PLY file in the Geo box. Do you maybe know how to solve this problem? Thank :)
make sure the PLY file is uncorrupted (try drag/drop into the TD network from the file explorer). if the issue persists, you can go inside the geo and replace the point file in TOP with your drag/drop point file in - should fix things
Thank you, I've made a scan with the app PolyCam and exported it to splat PLY. I imported the file in TD and it worked. Unfortunately I ran in another problem, because I don't see the colour textures. Only the colour Blue and Red. Does anyone know how to solve this? Thank you in advance. :)
@@SonicIdentifications mac or windows? blue and red probably means a glsl shader error, check in the color COMP and see if that is the problem. I think there is an issue with some graphics card drivers due to the number of inputs needed for the color shader. you could probably get around this by splitting the shader into two passes
@@water__shed Thanks, how can I split the shader in two passes? :)
This is great Lake
thank you! glad you are finding it helpful
that several seconds of looking for something that you are starting directly at (@ 11:15) is too real 😂😂 Amazing tutorial so far, thank you! been learning a ton from your videos recently
hahaha yes it happens wayyyy more than it should

So cool. Just a small step for Lake, but a giant leap for me.
tutorial please?

hi Lake! one q... i'm having a hard time with the autosave with python... does this NEEDS to be done in order to continue? (it keeps showing me errors although my code is the same as in the video) thanx!
no, that is not essential to complete the rest of the tutorial
Hello Sir, sorry to bother you, it seems to be the problem of my computer itself, I followed your steps to program, but did not change the horizontal number of lines, I would like to ask you to copy your TD source file to learn

For some reason when I try and get the text to show up instead of changing to the location it just displays parent().par.location.eval() I've been through the tutorial twice and I'm not sure what I'm doing wrong.
perhaps you are writing text, and not a parameter expression (make sure the second, green little check box is ticked on the left when the parameter is expanded) - see interactiveimmersive.io/touchdesigner-parameters/

coool!!

the geo SOP doesnt seem to exist anymore. The closest seems to be the point SOP but it doesnt have the same options. What am I missing?
geo is a COMP
Hey! Great tutorial thank you. I was wondering what would be the easiest way to make a shortcut that says that when I press spacebar, the alpha of a constant TOP goes from 0 to 1. But it only stays at 1 as long as I am pressing the spacebar, if I release, it goes back to 0. Any ideas? Ideally I would just do it with a KeyboardIn CHOP but you can't put spacebar there.
hmm, you probably need to override the built in keyboard shortcuts - might be some answers in this thread forum.derivative.ca/t/spacebar-play-disable/955/5
Hey, thanks for the great video! I'm thinking about buying the recently released Slamtec RPLidar C1 for a project I'm working on, do you think it would be compatible with this pluging ? Thanks
unfortunately i cannot say for sure. their s2 model is the higher end version I use in installations and (should) work with the same plugin, but for example their A1 model did not work for me

Thank you so much for posting this! You make incredible work and I appreciate how well you explain things. I had been looking for a tutorial that connects APIs into TD so this video is a perfect starting point for me. I would love an in-depth tutorial that goes deeper into the data aspects and how they're connected. Thank you!!
thank you@ im happy you found it useful. and thanks for the feedback! i have a couple older tutorials using the citibike rideshare API and a weather API that might be useful for you as well (the citibike tutorial is in a few parts and i get much deeper into the data usage side of things)
thanks, great tutorial. I'm having problems setting up the base_ at the beggining with the noise and the null. I dont get the component edition at first. Can anyone help me please?

I am clueless on cplusplus , if i make the build on a pc will it work on another pc if i just take the dll file? If not why is that?
yah the dll should be all you need for it work on another machine (assuming the new machine has the same driver / os installed, i cannot speak to machines with significantly different configurations, one .dll works for all of my PCs) can also check out the releases on the github page, there are some .dll files that might work out of the box. if not, you will need to build on your machine to generate a good .dll file github.com/thepelkus-too/SlamtecLidarTDCPPCHOP/releases/tag/0.2
@@water__shed NICE ! Thank you! I will get my hands on one in about 10 hrs, i'm so excited to test it out.
NICE! thank you.
@@water__shed Do you know what is the deal with COM's? After COM10 no port seems to work to connect to the LiDAR.
there are some limitations based on your PC as to how many com ports you have open at a time. if your ports are not closing after you unplug the device, try manually closing the ports via device manager (you can google for instructions) and / or restarting the computer
Very cool. But sadly in GLSL. And that I will never understand...
never say never :) this was using the pre-built particlesGPU actually, very little GLSL coding involved
and thank you !
wonderfull
thank you as touchdesigner user. i have some question. how do i stop lidar? any signal send in touchdesigner or dll file?
you can stop the lidar by unplugging it (this is the only way to stop power supply to the device), but of course you can simple ignore the data from inside TouchDesigner if you dont want to manually unplug
nice tutorial! is this possible to achieve with the free version of touch designer?
yep! you will just be limited in your render resolution (and you will need to make sure you have point cloud files that are under 1280x1280
