How thien-lee-44/synthetic-data-engine works

This is a Python 3D scene editor and synthetic-data engine. Users author ECS-based scenes in the Qt interface, manipulate and render them through the engine facade, then save/export projects or generate labeled computer-vision datasets and run benchmarks. The graph preserves the documented editing, rendering, animation, asset, serialization, and synthetic-data capabilities. Some UI and rendering internals are unsampled; their connections are omitted unless supported by the README or source index.
