it loads threejs webgpu in deno to be lighter weight than dealing with browser stuff, pumps scene files that the models create through a main script that deals with rendering stuff and effects, comes with a ton of helpers for various screenspace effects, including depth ones (like the volumetric clouds, those are screenspace), as well as a ton of different helpers for various other things like the grass, placing objects properly, character controlling (uses vrm as a humanoid skeleton standard since three doesn't have a native standard), applying SPOM, creating motion graphics overlays, loft modeling, pulling content directly from free/CC0 online libraries for models and textures on top of the ones that will come with it, moving vehicles in the proper direction, doing camera work, procedurally building cities and suburbs, etc.
