Convert an Image of Points to a particle Sim with Optical Flow

Hi Guys!

Working for the first time with Optical Flow and ran into an issue.

It’s quite stupid, I’m looking to convert an image of points into an interactive particle sim, the stuff that you’ve all probably seen in videos where someone is walking across a wall and the points move with them in a way.

Now it’s very important that these points are drawn from a specific image of points, If you guys have ever worked with AudioStellar, I’m pretty much trying to simulate the cursor as it moves through the points.

Most of it works well, I have the points in a particleGPU, laid out correctly. The idea is that as a person walks past the screen of points the points move using optical flow.

The issue is I can not for the life of my figure out how to get the 1:1 ratio. The field of points are super small within particleGPU and the slightest movement affects all of them. I have the optical flow size remap set to the correct aspect ratio. I just can’t figure out how to make the points bigger to fill up the remaining space in particleGPU.

Thanks for your help!
