flutter3d_core

The engine's rendering core with no Flutter SDK behind it (mcp-03n): scene graph, render list, passes, materials, animation, and model/material loading down to the one call each still needs an injected reader or decoder for.

flutter3d is the thin Flutter shell over this package that most applications actually depend on — BundleAssetSource, defaultImageDecoder, and the widgets. A modeller's document layer, the tool an agent starts with dart run, and a service checking an uploaded asset depend on this package directly instead, since none of them has a window in front of it.

Libraries

flutter3d_core
The engine's rendering core, with no Flutter SDK behind it.
formats
The formats a model arrives in and leaves in: the document every decoder produces, the materials it names, the readers and writers for glTF/GLB, OBJ, STL, USDZ and the engine's own .f3d and .fmat, the FBX decoder that recognises a file and refuses it with a reason, the image codecs, and the KTX2 container a compressed texture sits in.
geometry
CPU-side geometry: vertex layouts, mesh data, shape generators and the ray arithmetic that reads them.
parity_scene
The scene two backends are asked to draw, so their pictures can be compared.
