Struct CullSubmission 

pub struct CullSubmission<'a> {
    pub instance_aabbs: &'a Buffer,
    pub instance_count: u32,
    pub batch_meta: &'a Buffer,
    pub batch_count: u32,
    pub counter: &'a Buffer,
    pub visible_out: &'a Buffer,
    pub indirect_out: &'a Buffer,
    pub shadow_pass: bool,
}

Inputs to one cull dispatch.

Buffer requirements:

• instance_aabbs: STORAGE. instance_count x InstanceAabb.
• batch_meta: STORAGE. batch_count x BatchMeta.
• counter: STORAGE. batch_count x u32, used as atomic counters. The renderer zeroes this slot before the dispatch.
• visible_out: STORAGE. Holds up to instance_count x u32, the compacted list of visible instance indices written by the cull pass.
• indirect_out: STORAGE | INDIRECT. batch_count x DrawIndexedIndirect (20 bytes per entry). The static fields (index_count, first_index, base_vertex, first_instance) come from the matching BatchMeta entry; instance_count is overwritten by the cull pass.

After the encoder runs, draw each batch with pass.draw_indexed_indirect(indirect_out, batch_idx * 20) using visible_out as the per-instance lookup buffer.

Fields

instance_aabbs: &'a Buffer

Storage buffer of InstanceAabb entries.

instance_count: u32

Number of valid entries in instance_aabbs (not the buffer capacity).

batch_meta: &'a Buffer

Storage buffer of BatchMeta entries, one per batch.

batch_count: u32

Number of valid entries in batch_meta.

counter: &'a Buffer

Storage buffer used for per-batch atomic counters. Must hold at least batch_count u32 slots. The cull pass zeroes the counters at the end of its dispatch so the same buffer can be reused across cascades or frames.

visible_out: &'a Buffer

Storage buffer that receives the compacted list of visible instance indices. Sized for at least instance_count u32 slots.

indirect_out: &'a Buffer

Storage / indirect buffer that receives one DrawIndexedIndirect entry per batch (20 bytes each).

shadow_pass: bool

true to run the shadow-cull variant on the main camera pass: the cull shader honours InstanceAabb::cast_shadows and skips entries with the flag clear. submit_cull_shadow forces this on regardless of the value here.
