<h1>Mapping on a flattened icosahedron</h1>

</div>

<div class="wrapper">
<h2>Icosahedron</h2>
<p>Let's map on an <a href="http://en.wikipedia.org/wiki/Icosahedron">icosahedron</a>.
<p>Each polyhedral face uses the <a href="http://mathworld.wolfram.com/GnomonicProjection.html">gnomonic projection</a> for ease of implementation.
<h2>Technical Notes</h2>
<p>The maps above were rendered using a custom version of <a href="http://d3js.org">D3</a>, modified to support clipping against arbitrary spherical polygons.
<p>This was necessary because unlike the <a href="../gnomonic-butterfly">octahedron</a>, the icosahedron cannot be unfolded exactly along a whole meridian.
<p>The <a href="https://github.com/d3/d3-plugins/tree/master/geo/polyhedron">polyhedral plugin</a> automatically generates an outline in geographic coordinates, which can be passed directly to D3 as a clip polygon.
