Manifold Editor

Nobody has claimed this yet.

The Manifold Editor is our game engine environment / asset editor built around the glTF standard. Both the interchange and authoring format will utilize glTF and should be capable of producing content for Third Room as well as exporting glTF content for use elsewhere.

The todo list below represents the tasks needed for a feature-complete 1.0 release. We plan on tackling this list in chunks, focusing on iteratively improving our demo environments.

The issue names no files, tests, or entry points. Start by selecting one narrowly scoped unchecked item from the checklist, such as a scene hierarchy command or viewport control, and locate the relevant Manifold Editor code. Done should be defined as completing that item and validating it in the editor or a demo environment, rather than addressing the full 1.0 roadmap.
