    If allowed more control over canvas clearing, one wouldn't have to override clearRect() on the 2D context to achieve the outline.

    so the problem is essentially that there's no air above the shape, because otherwise you could just rotate the edges, right? which would imply that a shape should never touch the ... er ... edges of the grid?

    uh-oh. earcut can't handle colinear points (), and the triangulation changes drastically for even the smallest changes in point offsets.

    added a wrapper for earcut.js and made inner points work by passing them as single-vertex holes. ... well, sort of, because it's fragile AF.

    this isn't going to work out like i had planned. oh well.

    TIL: macOS ships with Grapher, a 2D/3D graph plotting app.

    Rediscovered an older unpublished notebook. Here are some shots of a single parameter change.

    I've started gathering some source material, and this video has been the best by far to get a close look at squid chromatophores (and some background info):

    In 's ortho projection I often lose track of angles, so I've updated my zdog helper collection with a rotation helper (and a zoom helper). Link:

    i accidentally set an invalid fill color in . as a result the last valid color by drawing order got used.

    it's all just cheap tricks. allow me to demonstrate :)

    A few more: interpolateCubehelixDefault (note the pattern at the bottom), interpolateSinebow, interpolatePiYG, interpolateWarm

    Will be published on @obervablehq in a bit (remind me in a week if I forget). Until then here's a debug view. Technique's basic line drawing (~8K thin ngons), with zdog used for transform matrices (to add additional rotation axes). The most time consuming part is tweaking params.
