Hi friends, i am using Zed 2i camera to make a particle system from body movement, so generating particles from that data is fine, but i am getting some delay on the movement of the particles because of the lifetime and position of those particles, I know and searched a lot and the OpticalFlow seems like a good interaction tool for the movement but as the zed is placed with a 45 degree angle the image has a different POV and seems that optical flow only works with an horizontal/front view of the camera, so how can I approach to have more reactivenes to the data input using the Particles GPU, searched a lot these days on all resources available and cant find anything that helps me to solve this.
