ShadowResources (Mibo)

ShadowResources Type

Namespace: Mibo.Elmish.Graphics3D.Pipelines
Assembly: Mibo.MonoGame.dll
Base Type: obj

Owns the shadow atlas + depth effect + pooled scratch the shadow pass needs, reused across frames. Constructed once by the pipeline; EnsureResources allocates the GPU atlas lazily against the real device on the first shadow pass.

Constructors

Constructor	Description
`ShadowResources(atlasCfg, biasCfg)` Full Usage: `ShadowResources(atlasCfg, biasCfg)` Parameters: atlasCfg : `ShadowAtlasConfig` biasCfg : `ShadowBiasConfig` Returns: `ShadowResources`	atlasCfg : `ShadowAtlasConfig` biasCfg : `ShadowBiasConfig` Returns: `ShadowResources`

Instance members

Instance member	Description
`this.Atlas` Full Usage: `this.Atlas` Returns: `ShadowAtlas`	The shadow atlas (owns the R32F RenderTarget2D, allocated lazily). Returns: `ShadowAtlas`
`this.BiasesScratch` Full Usage: `this.BiasesScratch`	Pooled scratch for the per-caster `shadowBiases` upload (receiver-side depth bias). Copied from `Atlas.Biases` each frame.
`this.BonePaletteScratch` Full Usage: `this.BonePaletteScratch`	Pooled bone-palette staging array for skinned casters (B12). Shader's MAX_BONES is 128.
`this.CollectedDrawCount` Full Usage: `this.CollectedDrawCount`	Opaque-geometry counts from the last unified collection. Populated whenever the shadow pass or a scene-depth pass collected geometry. The scene-depth render reads the same collected arrays (all entries), while the shadow render reads only `CastsShadow` entries.
`this.CollectedInstancedCount` Full Usage: `this.CollectedInstancedCount`
`this.CollectedModelPartCount` Full Usage: `this.CollectedModelPartCount`
`this.CollectedSkinnedCount` Full Usage: `this.CollectedSkinnedCount`
`this.Draws` Full Usage: `this.Draws`	Pooled caster mesh draws collected from the buffer (gated by EnableShadows/DisableShadows).
`this.Effect` Full Usage: `this.Effect`	The depth-only effect (DepthShadow.fx), loaded lazily on first shadow pass.
`this.Frustum` Full Usage: `this.Frustum` Returns: `BoundingFrustum`	Reused per-caster frustum (updated in-place via .Matrix) to avoid per-frame allocation. Returns: `BoundingFrustum`
`this.InstanceStaging` Full Usage: `this.InstanceStaging`	CPU staging array for the per-instance `VertexInstanceWorld` rows. Grows to the largest instanceCount seen across collected instanced casters. Reused across frames.
`this.InstanceVertexBuffer` Full Usage: `this.InstanceVertexBuffer`	Growable per-instance vertex buffer for instanced shadow casters. Owned by the shadow pass (not shared with the forward-pass PBR instance VB) so the two passes never race on it. Disposed at shutdown; recreated when an instanced caster exceeds the current capacity.
`this.InstancedDraws` Full Usage: `this.InstancedDraws`	Pooled instanced-caster draws (the world's block grid etc.). Grows on demand.
`this.ModelPartDraws` Full Usage: `this.ModelPartDraws`	Pooled static-ModelMeshPart caster draws (DrawModel/DrawModelWith). Grows on demand.
`this.Origin` Full Usage: `this.Origin`	The frame's shadow-origin override (SetShadowOrigin); ValueNone = use the atlas strategy.
`this.Params` Full Usage: `this.Params`	Cached depth-effect parameter handles (built when the effect loads).
`this.PointShadowSlots` Full Usage: `this.PointShadowSlots`	Per-light shadow slot mapping, indexed by lights.PointLights/SpotLights position; -1 = no shadow.
`this.Raster` Full Usage: `this.Raster`	Cached RasterizerState (polygon-offset bias + back-face culling). Created once on first shadow pass; disposed by the pipeline. Avoids per-frame GPU-state allocation.
`this.ShadowResult` Full Usage: `this.ShadowResult`	The last frame's shadow pass output — read by the forward pass (Shade overrides + user-effect scopes) so a custom shader can opt into shadow sampling. ValueNone when no shadow-casting light exists or DepthShadow.fx is unavailable.
`this.SkinnedDraws` Full Usage: `this.SkinnedDraws`	Pooled skinned-caster draws (B12). Grows on demand.
`this.SpotShadowSlots` Full Usage: `this.SpotShadowSlots`	Per-light shadow slot mapping for spot lights; -1 = no shadow.
`this.UVOffsetsScratch` Full Usage: `this.UVOffsetsScratch`	Pooled scratch for the multi-caster shadowUVOffsets upload.
`this.ViewProjsScratch` Full Usage: `this.ViewProjsScratch`	Pooled scratch for the multi-caster shadowViewProjs upload.
