Just wondering what thought (or code) has been put into 3d tiling in Cesium? By this I mean if we think of map tiling as being a 2d quadtree, the 3d extension of this would be an octree. Applications I’m thinking of include LOD based serving of data that has a lot of information vertically e.g.
meshes with high detail
Also, what are the standards for this? e.g. Is there a 3d extension of WebMercator?
