Struct CullStatus 

pub struct CullStatus;

The per-object outcomes the GPU cull records in its status buffer. Metal’s ICB encode kernel is told which one to draw rather than declaring them itself.

Implementations

impl CullStatus

pub const DRAWN: u32 = 0

Visible in phase 1, drawn by the main pass.

pub const HIZ_CANDIDATE: u32 = 1

Hi-Z-occluded in phase 1; the only outcome phase 2 re-tests. Under single-pass occlusion no phase 2 runs, so this is the settled outcome of a Hi-Z rejection.

pub const CULLED: u32 = 2

Frustum-, distance- or disabled-culled; settled.

pub const REDRAW: u32 = 3

A candidate phase 2 found visible, drawn by the disocclusion pass.

pub const HIZ_CULLED: u32 = 4

A candidate phase 2 found still occluded by this frame’s own depth.
