Per-grid static metadata: offsets into the concatenated storage buffers + the grid’s slot-pool dimensions. Uploaded once.

GPU.7 changes: chunks_dims and origin_chunk were dropped. The shader uses modular slot indexing (chunk_idx & (pool_dims - 1)) and verifies slot identity via slot_chunk_idx[slot], so the upload-time bbox is no longer relevant to the shader.

Fields

occupancy_offset: u32

occupancy u32-word offset where this grid’s data starts.

color_offsets_offset: u32

colors_offset: u32

chunk_colors_base_offset: u32

chunk_occupancy_offset: u32

slot_chunk_idx_offset: u32

New in GPU.7: u32-word offset where this grid’s slot_chunk_idx array starts (one vec3<i32> per slot, i.e. 3 u32 words each, plus 1 padding word for std430).

vsid: u32

total_slots: u32

pool_dims: [u32; 3]

_pad0: u32

occ_words_per_slot: u32

GPU.11 — per-slot occupancy stride (sum over all mips). meta_id’s occupancy slab starts at occupancy_offset + meta_id * occ_words_per_slot.

offsets_words_per_slot: u32

GPU.11 — per-slot color_offsets stride (sum over all mips).

mip_count: u32

GPU.11 — number of mip levels stored per slot.

_pad1: u32

mip_occ_rel: [u32; 6]

GPU.11 — within-slot u32 offset where mip m’s occupancy starts. mip_occ_rel[0] == 0 so mip-0 reads are unchanged.

mip_coff_rel: [u32; 6]

GPU.11 — within-slot u32 offset where mip m’s color_offsets start. mip_coff_rel[0] == 0.
