Struct MipLayout 

pub struct MipLayout {
    pub mip_count: u32,
    pub occ_words_per_slot: u32,
    pub offsets_words_per_slot: u32,
    pub mip_occ_rel: [u32; 6],
    pub mip_coff_rel: [u32; 6],
}

GPU.11 — per-slot occupancy/color-offset strides + per-mip within-slot relative offsets for a grid of side vsid. All chunks of a grid share these (uniform mip count by gpu_mip_count). colors keep their fixed COLORS_PER_CHUNK_WORDS stride; each mip’s colours are concatenated within that block and indexed by the chunk’s own (absolute) color_offsets.

Fields

mip_count: u32

Number of mip levels stored per slot = gpu_mip_count(vsid), always 1..=MAX_GPU_MIPS.

occ_words_per_slot: u32

Occupancy u32 words per chunk slot, summed over all mips — each mip stores its textured and solid bitmap back-to-back, so this is Σ 2·(vsid>>m)²·occ_words_per_column_for_mip(m).

offsets_words_per_slot: u32

color_offsets u32 words per chunk slot, summed over all mips (Σ (vsid>>m)² + 1 — each mip keeps its own cols + 1 prefix table).

mip_occ_rel: [u32; 6]

Within-slot u32 offset where mip m’s occupancy starts.

mip_coff_rel: [u32; 6]

Within-slot u32 offset where mip m’s color_offsets start.

Implementations

impl MipLayout

pub fn for_vsid(vsid: u32) -> Self

Compute the per-slot layout for a grid whose chunks are vsid × vsid × CHUNK_Z voxels. Deterministic in vsid, so the upload, GpuSceneResident::refresh_chunk, and the shader all derive identical strides independently.

Trait Implementations

impl Clone for MipLayout

fn clone(&self) -> MipLayout

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for MipLayout

impl Debug for MipLayout

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
