David Katz's setup only needs a browser and a webcam.
David Katz, Creative Director at HTC VIVE, created tech magic: a particle simulation that can be manipulated with your hands.
In his video showcase, he moves a ball in the waves of 100,000 particles, making them react to the movement, and to do this, he only needs a browser and a webcam.
You can try the simulation out yourself using your mouse (thanks, HTC):
The project was made with MediaPipe and Three.js – a popular combination in such experiments. You can see similar works done by Vasant Verma, Steven Mark Kübler, and Kat Zhang on 80 Level.
