Struct OitTargetDesc 

Source 
pub struct OitTargetDesc {
    pub accum_format: TextureFormat,
    pub reveal_format: TextureFormat,

Expand description

Targets used by the order-independent transparency (OIT) pass.

Weighted-blended OIT writes to two MRT attachments: an additive accum target and a multiplicative reveal target. A plugin transparent pipeline must declare both targets in the same order and use the published blend states, or the composite will reject the output.

Fields§

§accum_format: TextureFormat

@location(0) accumulation target. Rgba16Float with additive blend.

§reveal_format: TextureFormat

@location(1) reveal target. R8Unorm with (0, OneMinusSrc) blend.

§depth_format: TextureFormat

Shared depth attachment (read-only LessEqual test, no depth write).

§accum_blend: BlendState

Blend state for the accum target.

§reveal_blend: BlendState

Blend state for the reveal target.

§sample_count: u32

MSAA sample count. OIT runs at the scene sample count.
