We’ve been working on some new tools for automated segmentation, and more importantly, rationalization.
Matt shared with me a bit on the method he used in his thesis for finding the centroid of an image sample. I made an attempt at producing such an effect solely with the tools built into Fusion, and managed a pretty nice result that’s not too shabby on the speed. I suspect it will be sped up a lot when we make it into a fuse or plugin, but the effect is nice just as a comp, as it speaks visually to a concept that doesn’t sound like it would be visual at all.
In this first video, the green crosshair is finding the barycenter of the various circles, taking their size, density, and softness into account.
In the next video, the same thing is happening, this time on a particle system. Ben thought the circle example was silly because circles are easy to solve for, and this method works per-pixel, so I wanted to show an example of that type of setup.
And here’s a comp to try out on your own.
