A safe, modern, tiny glTF loader for C++ 17.
What this is:
- A tiny glTF deserializer which maps JSON objects to appropriate C++ structures.
- Intended to be safe for loading untrusted input.
- Slightly tailored to the needs of Minetest.
What this doesn't and shouldn't do:
- Serialization
- Loading images
- Resolving resources
- Support glTF extensions
- Add GLB support.
- Add further checks according to the specification.
- Everything in the JSON schema (+ indices and misc. stuff) is already validated. Much of the code was generated by a Lua script from the JSON schemata.
- Consider base64 rewrite.
