Particles and silhouet from Person moving

Hello,

i want to ask if somebody can give me some hints how to make something like in the video using TouchDesigner.
youtube.com/watch?v=BF_3lNdRNjs

I am able to track a person by infrared camera and get black/white pictures of the silhouet.
How can i interact with particles using the silhouet?

thanks in advance and regards
Dirk

Hello Dirk, I just moved this topic to the area for questions. Cheers!

I’d say you can try feeding the video to an Edge TOP and then to a Trace SOP which will give you geometry for the contour, and then you can use that as a particle emitter.

Hi Dirk,

this could be a combination of the particlesGPU component and the opticalFlow component which both of them you can find in the Palette>Tools section of the latest TouchDesigner099.

You would have to use the output of the optical Flow as a Force on the particles - so some glsl programming would be necessary.

Perhaps something we should add as an input to the particlesGpu

I am interested in the subject, can you obtain some possible configuration to make the project work ???
