It doesn't seem (from google trends) that anyone's coined this term so I'd like to: Twitter's been slopified

So I made a bauble world, took the shader code and added my map projection function. There's a page with it here sprawledoctopus.com/bauble-peirce/ . May be slow based on your graphics card, but it looks a bit like this (press arrow keys & w & d to move around)

There are lots of map projections and they all do the same thing: turn a sphere into a flat shape (usually a rectangle). You can invert this logic, and for a rectangle look outwards at the spherical angle. I wrote some shade code that does this and then used panoramic images

But the point of Bauble is it creates shader code - code that runs on a graphics card - live, not just a video. I've done one bit of shader code before with that most venerable of map projections: the Peirce Quincuncial projection sprawledoctopus.com/panorama/

I've been playing with shapes, made some chess pieces. Now I want them to make random (but legal) moves, rabbit holes are everywhere.

SDFs have other tricks, like being able to repeat them endlessly in a single stroke. They don't have to stay identical, here I give them different colours. LOOK HOW GOOPY IT GETS

Back to Bauble: what it allows is to create things so quickly and simply. I'd watched a video about SDFs which gave an example of a ball passing through a rotating cube. Once it was over I opened Bauble and within minutes I'd done it

This generalises to 3d, and you can combine objects together, either union, intersection or subtract one from another. And when combining, you have the option to smooth out. This is the first joy with SDFs, because everything's a distance your world is built out of clay, you can smoosh things

There are SDFs for various shapes, the thing to note is how the distance field ends up softening. Take the rectangle: going outward from the sides produces straight lines, but at the borders it rounds off. So you can round off an object just by adding a fixed number to your distance

Bauble allows rendering of 3d spaces with "signed distance function" (SDFs). This just returns a value of how far away any point is from it. Here's a representation of the SDF for a circle, the white represents distance 0, the bands represent 1, 2, 3. Inside the distance is negative (hence "signed")
