Cesium-Native How to read quantized Mesh

General
1

Hi,

I would like to read QuantizedMesh data with cesium-native.

I could read the layer.json and then would like to read the tiles

 QuadtreeTileID tileID((uint32_t)i, (uint32_t)k, (uint32_t)l);

 CesiumGeometry::Rectangle tileRectangle =
     tilingScheme.tileToRectangle(tileID);
 BoundingRegion boundingVolume = BoundingRegion(
     GlobeRectangle(
         tileRectangle.minimumX,
         tileRectangle.minimumY,
         tileRectangle.maximumX,
         tileRectangle.maximumY),
     0.0,
     0.0,
     Ellipsoid::WGS84);

 QuantizedMesh<uint16_t> quantizedMesh = createGridQuantizedMesh<uint16_t>(
     boundingVolume,
     verticesWidth,
     verticesHeight);

 std::vector<std::byte> quantizedMeshBin =
     convertQuantizedMeshToBinary(quantizedMesh);
 std::span<const std::byte> data(
     quantizedMeshBin.data(),
     quantizedMeshBin.size());

 QuantizedMeshLoadResult loadResult =
     QuantizedMeshLoader::load(tileID, boundingVolume, "myUrl", data, false);

As a result I get QuantizedMeshLoadResult.

Is there a description of this objekt - where do I find the mesh-data ? Is this in CesiumUtility::ExtensibleObject ?
