Enum SubstrateSpec 

pub enum SubstrateSpec {
    Mean,
    Average {
        block: u32,
    },
    Blur {
        radius_px: f32,
    },
}

A low-frequency copy of a shader’s source the renderer packs beside it and hands the shader through a reserved substrate region slot.

Variants

Mean

The componentwise source mean over the layer’s bounds, stored in one texel. Filter padding is excluded; bounds are clipped to the capture and rounded outward to texels. The renderer averages rows and then columns in its render-target format. A capture outside the layer uses its complete source.

Average

The source averaged in blocks of block x block texels, one substrate texel per block.

Fields

block: u32

Blur

The source blurred by a Gaussian of radius_px device pixels, kept at the blur’s scratch resolution.

Fields

radius_px: f32
