Tracking a physical objects

General TouchDesigner Discussion

I am planning to use multiple physical cubes to control the position and rotation of a boxSop in TD. In best case, the sensor should be hidden. How could I realise that?

I found out that BlackTrax Beacons could be a solution, but this system semms to be very expensive. Is there a nother way?

For one-dimensional motion, you can consider using a TOF distance measurement sensor combined with a gyroscope sensor. If three-dimensional tracking needs to be achieved, the UWB solution can be considered.

Hi @niknaim79,

one solution could be to try ZigSim on second hand iPhones glued inside the cubes.

ZigSim can communicate pretty much all sensor values from the phone and communication would be via wifi.

All right, thanks ninjai. Do you have a good starting point since I never used used a TOF Sensor up till now? Whats is is the advantage of UWB and is there a good tutorial/startingpoint for this?

Hello Markus,
I thought about that indeed, bit the I still dont have the position of the cube in the room, right?

For development purposes, a UWB kit equipped with IMU capabilities is required. Conventional UWB systems typically offer a positioning accuracy of around 10 cm. The key technical challenge lies in the integration of positioning data and IMU data into TD.

Hi @niknaim79,

yes, this would only give you relative transforms.

Ah so ZIGSIM also give me the position of the phones. So it seems this could work! I will try it out.
