Since the 3D Tiles validator calls the glTF validator it makes the C++/Rust route a little less attractive knowing we won't have a full native solution. For that reason I'm...

> Referring to the current [`3d-tiles-validator`](https://github.com/CesiumGS/3d-tiles-validator) repository, there is the question of whether the `validator`, `tools` and `samples-generator` will be separated (and if so: how). Ideally they would be separate...

@javagl good timing - I already did this in https://github.com/CesiumGS/3d-tiles/tree/3d-tiles-next-json-schema-2020-12 and plan to open a PR soon.

Fixed in https://github.com/CesiumGS/3d-tiles/pull/497

3D Tiles schemas are mostly followed what glTF is doing. If glTF changes we should change here as well, but until then maybe not worry about it?

Other thoughts: * If requiring a `mimeType` in each content is too verbose we could consider defining a top-level default that can be overriden. This isn't as big a concern...

I recently ran some tests for Draco vs. meshopt in CesiumJS * Source data: https://zenodo.org/record/5578198#.YhzAVlvMJzU * Number of points: 313,605,932 * Properties: position, color (other properties in the source data...

In addition to a new resources page (https://github.com/CesiumGS/3d-tiles/pull/680) we should also make a new ecosystem diagram. 2016|[2017](https://prismic-io.s3.amazonaws.com/cesium/6f132482-c81a-4f5a-af4d-a03786ae7347_Cesium-Carto-BOF-2017.pdf)|2019 --|--|-- |||as And for reference here are some of the glTF ecosystem diagrams...

This has mostly been addressed in https://github.com/CesiumGS/glTF/pull/51, but one open question is how runtime engines will support interaction with features defined by global feature IDs. CesiumJS has the concept of...

I'm reading this again after having opened https://github.com/CesiumGS/3d-tiles/issues/641. It seems like the most important decision is this one. > inheritance is only defined between _classes_, not between arbitrary instances I'm...
