Struct PreparedHillshadeRaster 

pub struct PreparedHillshadeRaster {
    pub tile: TileId,
    pub generation: u64,
    pub image: DecodedImage,
}

Prepared hillshade raster derived from a DEM tile.

The texture stores an encoded normal vector in RGBA8:

• R = normal.x mapped from [-1, 1] to [0, 255]
• G = normal.y mapped from [-1, 1] to [0, 255]
• B = normal.z mapped from [0, 1] to [0, 255]
• A = 255

Renderers can sample this in a dedicated hillshade pass and apply style-layer colours and opacity independently from the preparation step.

Fields

tile: TileId

Tile this prepared hillshade raster corresponds to.

generation: u64

Elevation-data generation used to produce the raster.

image: DecodedImage

Encoded hillshade normal texture.
