Interface QuantizedMeshTile

Quantized horizontal coordinate, [0, 32767] across [west, east].

Quantized vertical coordinate, [0, 32767] across [south, north].

Quantized height, [0, 32767] across [minHeight, maxHeight].

Triangle-list indices (3 per triangle).

Oct-decoded per-vertex normals (3 floats each), if the octvertexnormals extension was present; otherwise undefined (caller computes geometric ones).

Parsed metadata extension (descendant availability), if present.

Decoded water-mask extension, if present. Either a whole-tile flag (size === 1, all land or all water) or a 256×256 per-texel grid (size === 256). See QuantizedMeshWaterMask.

Set when this tile was synthesized by upsampling a parent (see upsampleQuantizedMesh) rather than decoded from real data — it carries no new detail, only fills a missing child quadrant to keep the quadtree hole-free at a data-availability boundary.
