SceneContext (Mibo)

SceneContext Type

Namespace: Mibo.Elmish.Graphics3D.Pipelines
Assembly: Mibo.MonoGame.dll
Base Type: ValueType
All Interfaces: IEquatable<SceneContext> , IStructuralEquatable
Kind: Struct

The scene state passed to a Draw3D.drawImmediate callback: the raw graphics device plus everything the pipeline gathered for the current frame (active camera, lights, the shadow pass output, elapsed time). Use it for fully-custom draws that need both device control and the scene data — water/refraction, screen-space effects, multi-pass.

Read-only snapshot of the frame's gather; mutate device state at your own risk (the pipeline restores viewport + camera scope around the callback). SceneContext.Shadows is ValueNone when no shadow-casting light exists.
