flutter3d_conformance

What flutter3d_hardware requires of a backend, as a suite the backend runs against itself.

void main() => runConformance(device);

An interface can only say that a call exists. This says that a clear covers the whole attachment, that uploaded pixels keep their row order, that the HDR format the backend names is really renderable, and that every stage pair the engine links does link.

The last one earns its place regularly. A varying a fragment stage reads and no vertex stage writes is a hard error in a browser and invisible on a backend whose pipelines were linked ahead of time — so the check catches, on one backend, a mistake that would ship on another.

Part of flutter3d, an independent implementation of a 3D engine for Flutter — not a fork or a binding of another engine, and not affiliated with the Flutter team. Three switchable rendering backends: Impeller via Flutter GPU, WebGL2, and a software rasteriser. glTF, OBJ and .f3d loading, six lighting models, shadows, bloom, skinning, animation, BVH culling and picking; a deterministic fixed-step game layer with collision, navigation, positional audio, and gamepad and touch input. Three example games — shooter, platformer, racing — each built on its genre package: flutter3d_game_shooter, flutter3d_game_platformer, flutter3d_game_racing. A new game starts from apps/flutter3d_template_app. Documentation: flutter3d.pleion.dev.
