I am new to Touch designer and i need some guidance.
I have this project to develop that seems very simple but i would like it to be the best it can.
The idea is to have a Led wall(5m by 3m) placed agains a wall in a very long and wide corridor.
The led wall will be reacting to the people passing in front of the screen.
For now i am just trying to find out what will be the advised equipment for the project.
Its an access corridor and many people will pass in front of the screen, at times big crowds will come thru at once and it would be great to be able to track every single person.
With this in mind what would be the advised equipment to get the job done?
Is one lidar enough or more is advised?
I came across this one, anybody work with it already? > Any Thoughts?
I will be using a 32core rizen threadripper with 2 rtx 280ti for testing, almost for sure i wont have process problems but when done, a new machine will be built for it, any advices on that set up will also be great
Any other advice will be welcome,
We’d recommend using Hokuyo lidar sensor for interactivity over a large wall or floor, they are comonly used in installations and directly supported with TouchDesigner’s Hokuyo CHOP.
Make sure you getr a model that is supported. Read the documentation here: TouchDesigner Documentation
2 Geforce GPUs isn’t a recommended setup. when using 2 GPUs you should go with Nvidia’s professional cards (Quadro, RTX, etc). You can reac about that also in our docuementation here: Using Multiple Graphic Cards - Derivative
Just a note about “TouchDesigner”, it is one word and spelt with a capital ‘T’ and ‘D’ in the name.
2D LIDAR can sometimes be hassle to deal with, with bigger crowds, you will need multiple lidars to prevent occlusion. Previously we had to calibrate each sensor together and then clean up the data further. If the space isn’t built with sensors in mind they can become misaligned or kicked by visitors.
For positional tracking on a floor, I now more often use cameras pointing down. With blob-tracking you can easily detect 2D positions of people on the floor. With IR blasters and filters on the cameras you can detect in low-light and ignore ambient or projected lights.
If you need more fidelity, Kinect or now Orbbec 3D cameras have great integrations with TouchDesigner and also have body tracking built in. This would be my recommendation for getting started with your project and TouchDesigner.
This seems a very good option, will it be accurate and low latency?
The astra2 sells for a very inviting price and according to specs, if they are to trust, its right in my needs.
