Struct BatchMeta 

#[repr(C)]
pub struct BatchMeta {
    pub index_count: u32,
    pub first_index: u32,
    pub instance_offset: u32,
    pub instance_count: u32,
    pub vis_offset: u32,
    pub is_transparent: u32,
    pub _pad: [u32; 2],
}

Per-batch metadata read by the GPU cull pass.

One entry per batch in the batch_meta storage buffer attached to a CullSubmission. Layout (32 bytes, 16-byte aligned):

• index_count: u32 - index range used by this batch’s draw
• first_index: u32 - index buffer offset (typically 0)
• instance_offset: u32 - first instance for this batch in the AABB buffer
• instance_count: u32 - number of instances belonging to this batch
• vis_offset: u32 - first slot in the visibility output buffer
• is_transparent: u32 - 1 marks a transparent batch
• _pad: [u32; 2]

vis_offset is a prefix sum of instance_count across batches; for a scene where instances are laid out contiguously per batch it equals instance_offset.

Fields

index_count: u32

Mesh index count for one instance.

first_index: u32

First index offset into the bound index buffer.

instance_offset: u32

Offset into the instance AABB buffer where this batch begins.

instance_count: u32

Number of instances in the batch.

vis_offset: u32

First slot in the visibility output buffer this batch writes to.

is_transparent: u32

1 if the batch is transparent, 0 for opaque.

_pad: [u32; 2]

Padding to keep the struct 16-byte aligned.
