Repulsive Surfaces (cmu.edu)

I was blown away by this presentation. Shared widely yesterday. We are test driving the code for possible use in pangenomic modeling of genomes of many individuals—-complex genomic graphs. Some of these methods may also have good applications in neuroimaging segmentation-—the brain split into non-overlapping regions and fiber tracts that should o”not intersect (at least in our models).


Can you elaborate further on this? Are you talking about reconstructing fiber tracts from DTIs?


Where's the code?

I watched this in a science museum display ~25 years ago. Was so confused at the time. Also though of it while reading this article's abstract.


Keenan Crane has been doing incredible work in this field for the last few years. I'm following his work avidly.


Fascinating and well narrated. I'm no math wizard but I found the explanation and illustration easy to follow. And the title of the video, "Repulsive Curves and Surfaces", is sure to draw some attention from the sheer amount of jokes it begs.


Some of the generated shapes are definitely kind of unsettling and "repulsive"!


Here I was hoping it was going to be more research on even more superhydrophobic surface textures.


I thought the same, but that was sufficiently weird.


I almost thought he had an extreme dislike for the Microsoft tablet PC's.


First though: anti-grav.


So if we take the extruder making Cheetos and add a large static electric charge to it, can we have snack food in these shapes?


This is also going to be huge for 3D scanning: https://youtu.be/sJgK0jjd6oE?t=188
