epsg4326 latLonToPixels xy
// 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

Where is EPSG:3857 in Leaflet?
map.getBounds().getNorthEast(); // LatLng(52.5262, 13.44907)
map.getPixelBounds().getTopRight(); // Point(2253845, 1375425) ???
map.getPixelOrigin(); // Point(2252165, 1375425) ???
L.Projection.SphericalMercator.project(
map.getBounds().getNorthEast()
); // Point(0.23473, 1.08117) !?!

array buffers for javascript webgl rendering for tile (8,137,83)

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
