TerrainTextureParameters

Description

sealed class Tinman.Engine.Rendering.Effects.Shared.TerrainTextureParameters

Derived from: RenderEffectParameters ^abstract

Shared render effect parameters for unique multi-texturing of the terrain.

The following low-level render effect parameter slots are always defined (N := TerrainSlotMapping.SlotCount):

'g_materialAlbedo', RenderEffectParameterType.Vector4
Texture atlas sources for albedo (RenderEffectParameterType.Vector4):
```
x := terrain layer slot index
y := component index for red
z := component index for green
w := component index for blue
```
Mapped to TextureSource.

'g_materialEmissive', RenderEffectParameterType.Vector4
Texture atlas source for emissive intensity:

x := terrain layer slot index
y := component index for grayscale reflectivity
z := scale factor for linear sample value
w := offset value for scaled sample value

Mapped to TextureSource.

'g_materialEmissiveColor', RenderEffectParameterType.Vector3
Emissive color, mapped to TextureSource.
'g_materialEmissiveFade', RenderEffectParameterType.Vector2
Emissive color fade range, mapped to TextureSource:
```
(x,y) := EmissiveFade.Flip().Mul(-1).ToLinearF()
```

'g_materialGloss', RenderEffectParameterType.Vector4
Texture atlas source for gloss:

x := terrain layer slot index
y := component index for gloss
z := scale factor for linear sample value
w := offset value for scaled sample value

Mapped to TextureSource.

'g_materialNormal', RenderEffectParameterType.Vector4
Texture atlas source for normal:

x := terrain layer slot index
y := component index for normal X-axis
z := component index for normal Y-axis
w := component index for normal Z-axis

Mapped to TextureSource.

'g_materialOcclusion', RenderEffectParameterType.Vector4
Texture atlas source for ambient occlusion:

x := terrain layer slot index
y := component index for ambient occlusion
z := scale factor for linear sample value
w := offset value for scaled sample value

Mapped to TextureSource.

'g_materialOpacity', RenderEffectParameterType.Vector4
Texture atlas source for opacity:

x := terrain layer slot index
y := component index for opacity
z := scale factor for linear sample value
w := offset value for scaled sample value

Mapped to TextureSource.

'g_materialReflectivity', RenderEffectParameterType.Vector4
Texture atlas source for grayscale reflectivity:

x := terrain layer slot index
y := component index for grayscale reflectivity
z := scale factor for linear sample value
w := offset value for scaled sample value

Mapped to TextureSource.

'g_materialReflectivityColor', RenderEffectParameterType.Vector3
Reflectivity color, mapped to TextureSource.
'g_terrainData', RenderEffectParameterType.Float
Depicts which material values to read from vertex data, instead from texture samples:
```
x := terrain-space normal vectors:
     0 : use normal map
     1 : use vertex data
```
Mapped to TerrainSlotMapping.Normal.
'g_textureCount', RenderEffectParameterType.Int
The number of used terrain slots, mapped to TerrainSlotMapping.
TexturingBatchParameters with TexturingBatchParameters.FlagNoTextureArray = FlagNoTextureArray, mapped to TextureAtlas.
