these things? brilliant. shapes for days.
Progressive Mapping
Successive iterations mapping rectangular coordinates to polar coordinates. It results in this very swirly looking fractal.

#ReleaseDay The new version of https://thi.ng/geom-sdf is automatically preprocessing the vertices given for 2D polygons & polylines to remove any coincident and colinear ones (using Douglas-Peucker algorithm). This avoids some degenerate cases, but can also speed up the SDF evaluation of converted shapes in some other cases...
Thanks to @made for reporting the issue! 🙏
(To clarify: This package is for converting 2D shapes/geometries/SVG to composable SDF JavaScript/TypeScript functions, not for shader-based SDF use cases. For the latter, the https://thi.ng/shader-ast-stdlib package provides similar SDF functions/operators, for use with https://thi.ng/shader-ast and transpilation to GLSL)
Some examples:
