A set of signed distance functions and utilities for use in WebGPU/TypeGPU apps.

``ts
import tgpu from 'typegpu';
import * as sdf from '@typegpu/sdf';
import * as d from 'typegpu/data';

const mainFragment = tgpu['~unstable'].fragmentFn({
in: { uv: d.vec2f },
out: d.vec4f,
})(({ uv }) => {
const distance = sdf.opSmoothUnion(
sdf.sdDisk(uv.sub(0.5), 0.25),
sdf.sdBox2d(uv.sub(0.5), d.vec2f(0.8, 0.05)),
0.1,
);

if (distance < 0) {
return d.vec4f(0, 0, 0, 1);
}
return d.vec4f(1, 1, 1, 0);
});
