The returned interpolator function takes a single argument t, where t is a number ranging from 0 to 1; a value of 0 returns a, while a value of 1 returns n. Intermediate values interpolate from a to n along the polygon's perimeter.\n\nYou can pass an optional boolean, which defaults to true, indicating whether to clamp t to the range [0, 1]. When clamp is false, the interpolator applies modular arithmetic to t. If t is less than 0, the interpolator wraps around the polygon's perimeter in reverse. If t is greater than 1, the interpolator continues forward along the perimeter.\n`","pinned":false,"hidden":false,"mode":"ojs"},{"id":71,"value":"viewof i = Inputs.range([-1, 2], { step: 0.01, value: 0, label: \"t:\" })","pinned":false,"hidden":false,"mode":"ojs"},{"id":403,"value":"viewof clamp = Inputs.toggle({ label: \"Clamp:\", value: false })","pinned":false,"hidden":false,"mode":"ojs"},{"id":176,"value":"interpolator = geometric.polygonInterpolate(polygon, clamp)","pinned":true,"hidden":false,"mode":"ojs"},{"id":37,"value":"{\n const svg = d3.create(\"svg\")\n .attr(\"width\", size)\n .attr(\"height\", size)\n .style(\"overflow\", \"visible\")\n\n svg.append(\"polygon\")\n .attr(\"points\", polygon)\n .attr(\"fill\", \"lightblue\")\n .attr(\"stroke\", \"black\");\n\n svg.append(\"circle\")\n .attr(\"cx\", point[0])\n .attr(\"cy\", point[1])\n .attr(\"r\", 8)\n .attr(\"fill\", \"tomato\")\n .attr(\"stroke\", \"black\")\n\n return svg.node()\n}","pinned":false,"hidden":false,"mode":"ojs"},{"id":145,"value":"viewof selection = Inputs.radio([\"Random\", \"Regular\"], { label: \"Type\", value: \"Random\" })","pinned":false,"hidden":false,"mode":"ojs"},{"id":180,"value":"viewof sides = Inputs.range([4, 64], { label: \"Sides\", value: 8, step: 1})","pinned":false,"hidden":false,"mode":"ojs"},{"id":157,"value":"polygon = polygons[selection.toLowerCase()]","pinned":true,"hidden":false,"mode":"ojs"},{"id":74,"value":"point = interpolator(i)","pinned":true,"hidden":false,"mode":"ojs"},{"id":79,"value":"polygons = ({\n random: geometric.polygonRandom(sides, area, [size / 2, size / 2]),\n regular: geometric.polygonRegular(sides, area, [size / 2, size / 2])\n})","pinned":true,"hidden":false,"mode":"ojs"},{"id":308,"value":"md`## Dimensions`","pinned":false,"hidden":false,"mode":"ojs"},{"id":212,"value":"area = size ** 2 / 3","pinned":true,"hidden":false,"mode":"ojs"},{"id":24,"value":"size = Math.min(width, 500)","pinned":true,"hidden":false,"mode":"ojs"},{"id":311,"value":"md`## Imports`","pinned":false,"hidden":false,"mode":"ojs"},{"id":13,"value":"geometric = require(\"geometric@3\")","pinned":true,"hidden":false,"mode":"ojs"}],"files":"$W31","stdlib":"1","titling":"auto"}
