Helper methods for terrain texturing with atlases.

[Pure]
public static method Coords → (5)

atlas ⁱⁿ : int32: The texture atlas index.
texCoords ⁱⁿ : float3: Global terrain mesh coordinates:
Tinman.Terrain.Vertices.Formats.HeightmapCoordinates(CoordinatePrecision.FloatHigh)
or
Tinman.Terrain.Vertices.Formats.HeightmapCoordinates(CoordinatePrecision.Float)
texCoordsExtra ⁱⁿ : float3: Global terrain mesh coordinates:
Tinman.Terrain.Vertices.Formats.HeightmapCoordinates(CoordinatePrecision.FloatLow)
or zero
coordsBase ^out : float2: Output coordinates for base texture.
coords ^out : float2: Output coordinates for texture.

Computes atlas texture coordinates.

[If("SHADER_PS")] [Pure]
public static method Sample → (4)

vertex ⁱⁿ : float4: The vertex color.
coords ⁱⁿ : float4 [ ] @ Length(Configuration.TERRAIN_TEXTURE_COUNT): The texture coordinates for the tiles.
distance ⁱⁿ : float32: The distance between the camera and the vertex.
opacity ^out : float32: The output opacity.
returns → Material: The material sample.

Fetches a material sample from the texture atlases.
