Wanderpin - getting routes to leave the ground

Live: https://wanderpin-ecru.vercel.app/

One update, mostly one stubborn visual I’d twice given up on: real lifted route arcs on the 3D map.

Arcs that finally hug the globe

deck.gl’s ArcLayer drifts on a MapLibre globe (it only knows Web Mercator), and my earlier hand-rolled layer compiled, ran, threw zero errors, and painted nothing. The fix came from reading MapLibre’s own shaders: inject its projection prelude and call projectTileFor3D(pos, elevation).

The thing I’d missed every time - elevation is in meters above the sphere, fed through five per-frame uniforms, not a raw matrix. Then the polish fights: a z-fight speckle (fixed by not writing depth), a 50 km minimum lift that made short hops launch like fireworks, and a fat vertical wall at city zoom (now fades out past ~zoom 10).

An optional day timeline

New “Days” view in the trip panel. Weekend trip? You’ll never see it. Month-long? Hit “Organize into days” and stops group into collapsible days you can split, reorder, fit the globe to, or play one at a time. A day is a contiguous slice of the route, so “move to Day 3” repositions the stop and re-normalizes - the route and itinerary stay honest. Days travel on share links too.

Where it stands

Live at site, (Also squashed a deploy bug: one .tsx API route made Vercel type-check the whole api/ folder with no tsconfig - a tiny api/tsconfig.json fixed it.)
