zum rendern brauche ich die vertices mit den pixel koordinaten (siehe vertex_array in arrays.js) und die entsprechenden indices für den draw call (siehe index_array in arrays.js).

um epsg:4326 oder epsg:3857 in pixel koordinaten zu convertieren habe ich dir die rechnung in conversions.js gepackt.

ich habe eine tile mit zoom=8, x=137 und y=83 als rohdaten in geojson unter tile_8_137_83.json abgelegt. die konvertierten und vorberechneten arrays sind in arrays.js.

tl;dr ich brauch ein vertex und ein index array im gltf. falls das format relevant ist, für die vertices nutze ich ein Float32Array und für die indices Uint16Array

	Generic Canvas Overlay for leaflet,
	Stanislav Sumbera, April , 2014

	- added userDrawFunc that is called when Canvas need to be redrawn
	- added few useful params fro userDrawFunc callback
	- fixed resize map bug
	inspired & portions taken from : https://github.com/Leaflet/Leaflet.heat

	// JavaScript

	// converts lat/lon to pixel x/y at zoom level 0 for 256*256 tile size , inverts y coord
	function latLonToPixels(lat, lon) { // lat, lon: epsg:4326
	var sinLat = Math.sin(lat * Math.PI / 180.0);
	var pixelX = ((lon + 180) / 360) * 256;
	var pixelY = (0.5 - Math.log((1 + sinLat) / (1 - sinLat)) / (Math.PI * 4)) * 256;
	return { x: pixelX, y: pixelY }; // object with .x and .y
	}
