Struct Plan 

pub struct Plan {
    pub phase1: Dispatch,
    pub tail: Option<Dispatch>,
}

The dispatches that build a mip_count-deep pyramid over a width x height depth source.

Fields

phase1: Dispatch

Depth source to mips 0..6. Always present.

tail: Option<Dispatch>

Mip 6 to mips 7..12. Absent when the pyramid stops at mip 6 or shallower.

Implementations

impl Plan

pub fn new(width: u32, height: u32, mip_count: u32, sample_count: u32) -> Self

Plan the two dispatches. mip_count is clamped to MAX_MIPS; a shallower pyramid than requested only costs the cull a coarser level to pick from, which makes it more permissive rather than wrong.

pub fn mip_count(&self) -> u32

Pyramid depth this plan actually writes. The image and the cull’s mip count must both use it: a mip the plan skipped is never written, and sampling one would feed the cull uninitialised memory.

pub fn bound_mips(base_mip: u32, mip_count: u32) -> impl Iterator<Item = u32>

Mips the dispatch starting at base_mip binds, clamped to the pyramid’s actual depth. Descriptors past the end repeat the last live mip so the array is fully populated; the kernel’s level_count keeps it from writing them.
