Building Shapes with Math | An introduction to signed distance functions
Over the past few months, I've been playing around with 2D signed distance functions (SDF's) in Godot. I also really wanted to submit something for the Summer of Math Exposition (SOME 4), an annual math explainer event hosted by @3blue1brown. So, I decided to make this: a video going over what SDF's are and some cool stuff you can do with them. I haven't really made a video like this before, so I'd appreciate any feedback or suggestions you have. And, of course, thanks so much for watching!
