Relative URLs in external tileset.json

[clausnagel]

I am currently experimenting with external tilesets and came across a question with relative URLs.
Assume a tileset a.json with a content.url pointing to another tileset b.json. b.json contains a content.url to a tile.b3dm content file. Further assume that a.json and b.json are not in the same path.

Now, my assumption was that a relative content.url to tile.b3dm must be given relative to b.json because it is referenced from this tileset. However, I was surprised to learn that it has to be relative to a.json. Is this the supposed behavior?

Cheers,
Claus

Thanks for bringing this up, a tile url should be relative to its tileset and not just the root tileset. I opened a pull request in Cesium: CesiumGS/cesium#3529

Thanks for the report, @clausnagel, and for the fix, @lilleyse.

I tweaked the wording in #68 to make this more explicit.

@lilleyse please close this when you merge #68.
