{unifir} binding

[trevorld]

• {unifir} provides R bindings for the proprietary Unity engine

  • Users would need to download and install Unity to do anything useful...

• Unity is documented as supporting Wavefront OBJ files: https://docs.unity3d.com/Manual/3D-formats.html which we can generate via save_piece_obj()

• There is also a Unity plugin that supports gltf assets which me may be able to generate from our existing {rgl} bindings via the {rgl2gltf} package

• The {unifir} documentation is here: https://docs.ropensci.org/unifir/

  Seems that {unifir} currently only provides first rate support to importing Unity "prefabs"?

  There are a lot of ways to actually bring assets into a Unity scene as things that users will interact with or otherwise be affected by in your environment. The easiest one of those to work with, which is the only one unifir puts much thought into, is referred to as a “prefab”.
