Thank you very much for Cesium. It's a great product with a lot of potential.
I want to implement my own quantized-mesh terrain server as a college project. Reading the documentation, I have some questions:
1. In QuantizedMeshHeader struct there are the BoundingSphere fields. Does the sphere is supposed to bound the 3d tile (with the heights), or only the 2d tile?
2. The VertexData arrays values are encoded with zigzag encoding. Why? (given that the types are unsigned)
3. I want to avoid the usage of water mark encoding in the indices list. Does the decoding code in the createQuantizedMeshTerrainData() function in the CesiumTerrainProvider.js file is the only thing I need to take into account? Is there another place which affected by this encoding?
Thank you very much
