#Interpolation

Erik<p>Look here. This is a method to make smooth and continuous non-orthogonal designspaces. In this example: 4 masters "on the outside" and 3 floating intermediates. (The shapes are from MutatorSans and only illustrate the extent of influence.) <a href="https://typo.social/tags/interpolation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>interpolation</span></a> <a href="https://typo.social/tags/experimental" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>experimental</span></a> <a href="https://typo.social/tags/designspace" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>designspace</span></a> <a href="https://typo.social/tags/math" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>math</span></a> <a href="https://typo.social/tags/somethingnew" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>somethingnew</span></a></p>
Karsten Schmidt<p>A couple of 2017 tests/prototypes using Shepard/IDW interpolation[1] to compute "soft" voronoi cells. Reposting this after <span class="h-card" translate="no"><a href="https://mathstodon.xyz/@Danpiker" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>Danpiker</span></a></span> was mentioning this method for 3D modeling in recent days. Coincidentally, these tests were for something v. similar, i.e. outsole traction pattern geometry generation — the exponent used in this method acts an easy-to-grok parameter to control softness/sharpness &amp; level of detail... Unlike these examples, which are only using point samples and colors, the idea was to interpolate between line geometries to create a relief surface. E.g. applied to an outsole, we could configure the interpolation to produce softer shapes in the heel region and more detailed ridges in the front foot, where traction is needed most... In the end I didn't use this specific interpolation method for performance reasons and switched to another approach to compute an SDF for v. similar results (see recent posts from yesterday).</p><p>(Alt text for more details about these animations)</p><p>[1] <a href="https://en.wikipedia.org/wiki/Inverse_distance_weighting" rel="nofollow noopener noreferrer" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">en.wikipedia.org/wiki/Inverse_</span><span class="invisible">distance_weighting</span></a></p><p><a href="https://mastodon.thi.ng/tags/ThingUmbrella" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>ThingUmbrella</span></a> <a href="https://mastodon.thi.ng/tags/Interpolation" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Interpolation</span></a> <a href="https://mastodon.thi.ng/tags/Image" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Image</span></a> <a href="https://mastodon.thi.ng/tags/Color" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Color</span></a> <a href="https://mastodon.thi.ng/tags/Voronoi" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Voronoi</span></a> <a href="https://mastodon.thi.ng/tags/Geometry" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>Geometry</span></a></p>

Updated the gradient image generator example to use a custom pixel format (using Oklab color space) for the floating point pixel buffer.

Using Oklab instead of RGB combined with the bicubic image interpolation used to compute the gradient image means the colors will also be interpolated in the Oklab space which is perceptually better & more correct than RGB and leads to more pleasing results...

Demo & source links are updated (see OP)

TypeScript source code of the custom pixel format definition: // define a custom pixel buffer format to store pixels in the Oklab color space: // using Oklab instead of RGB combined with the bicubic image interpolation used // to compute the gradient image means the colors will also be interpolated in // the Oklab space (which is perceptually better [more correct] than RGB and // leads to more pleasing results)... const FMT_OKLAB = defFloatFormat({ // technically, we're not using the alpha channel here, but it makes it // easier to handle alpha: true, // channel order channels: [3, 2, 1, 0], // custom conversions to & from packed integer ABGR format (needed for HTML canvas) convert: { // convert: 32bit int -> sRGB -> Oklab fromABGR: (x, out) => convert(out || [], intAbgr32Srgb([], x), "oklab", "srgb"), // convert: Oklab -> sRGB -> 32bit int toABGR: (x) => srgbIntAbgr32(convert([], x, "srgb", "oklab")), }, }); // ...then use as format with floating point pixel buffers like so: const img = floatBuffer(width, height, FMT_OKLAB)
