L.TileBuffer

WebGL tile buffer objects for leaflet, storing vertex, index and color array buffers and tile information.

Requires

• Leaflet 0.7.7 or later

L.TileBufferCollection

WebGL tile buffer object cache for leaflet, storing all loaded tile buffers on current zoom level.

Requires

• Leaflet 0.7.7 or later
• L.TileBuffer

Usage

  /* init cache for tile buffers for current zoom level */
  TILE_CACHE = L.tileBufferCollection(map.getZoom());

  /* [...] create buffers for the tile [...] */

  /* create a tile buffer object for the current tile */
  var tileBuffer = L.tileBuffer(vtx, idx, clr, {
    x: tile.x,
    y: tile.y,
    zoom: map.getZoom()
  });

  /* make sanity check on the tile buffer cache */
  if (TILE_CACHE.getZoom() != map.getZoom()) {
    TILE_CACHE.resetOnZoom(map.getZoom());
  }

  /* add tile buffer geometries to the collection */
  TILE_CACHE.add(tileBuffer);
