ShadowResult (Mibo)

ShadowResult Type

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

The shadow pass output for a frame: the atlas texture + the packed shadow-sampling uniforms a shader consumes. ShadowResult.Atlas is the depth atlas (sampler slot 5, PointClamp); the arrays are already sized to the active caster count.

Built by ShadowPass.run; ValueNone when no shadow-casting light exists or DepthShadow.fx is unavailable. A custom/user effect opts into shadows by declaring these uniforms (by name) — see SceneUpload.uploadToEffect.

Record fields

Record Field	Description
`ActiveCasterCount` Full Usage: `ActiveCasterCount` Field type: `int`	The number of active caster regions (the live length of the packed arrays). Field type: `int`
`Atlas` Full Usage: `Atlas` Field type: `Texture2D`	The shadow depth atlas (R32F). Bind to sampler slot 5 with PointClamp. Field type: `Texture2D`
`Biases` Full Usage: `Biases` Field type: `float32[]`	The per-caster receiver-side bias (`shadowBiases[]`), preventing self-shadow acne when a surface both casts and receives (e.g. the instanced floor). Field type: `float32[]`
`DirLightCastsShadows` Full Usage: `DirLightCastsShadows` Field type: `bool`	Whether the directional light casts shadows (the `dirLightCastsShadows` flag). Field type: `bool`
`PointLightShadowIdx` Full Usage: `PointLightShadowIdx` Field type: `int[]`	The per-point-light shadow atlas slot (-1 = no shadow), indexed by PointLights position. Field type: `int[]`
`SpotLightShadowIdx` Full Usage: `SpotLightShadowIdx` Field type: `int[]`	The per-spot-light shadow atlas slot (-1 = no shadow), indexed by SpotLights position. Field type: `int[]`
`TexelSize` Full Usage: `TexelSize` Field type: `float32`	`1.0f / atlasResolution` — for the `shadowTexelSize` PCF spread. Field type: `float32`
`UVOffsets` Full Usage: `UVOffsets` Field type: `Vector4[]`	The packed `shadowUVOffsets[]` (atlas-region UV scale/offset per caster). Field type: `Vector4[]`
`ViewProjs` Full Usage: `ViewProjs` Field type: `Matrix[]`	The packed `shadowViewProjs[]` (one per active caster region). Field type: `Matrix[]`
