Hello everyone! I’m a student, and I’m relatively new to the world of Openframeworks: I know the basics and all its possibilities, but I miss the extra step that I need to accomplish an averagely complex project. So I ask for some help here
I want to create a project like this one on the video below:
There’s a similar topic on this forum, but unfortunately it’s not very useful. Do you have a general idea on how to implement a project like this? What’s the best (and the simplest) way to attach the particle system at the movements on the webcam?
That type of stuff use a technic called “optical flow” ,with that you can calculate the movement of an image between frames.
So with that you can affect a particle system, for example the acceleration of the particle.
With optical flow you get an array with values of the difference between frames, so you can ask if that value y more than “0” for example, if that happened you create a new particle, for example.
I think the process to make that, first its try to make work some add-on of optical flow, and saw the results, then you can follow with the implementation of the particle system.
