Struct GpuBinMetadata 

#[repr(C)]
pub struct GpuBinMetadata {
    pub indirect_parameters_offset: u32,
    pub bin_index: u32,
    pub instance_count: u32,
}

Information about each bin in a batch set.

This is maintained by the CPU and cached for bins that don’t change from frame to frame.

Fields

indirect_parameters_offset: u32

The index of the indirect parameters for this bin, relative to the first indirect parameter index for the batch set.

That is, the final indirect parameters index for this bin is first_indirect_parameters_index in the UniformAllocationMetadata plus this value.

bin_index: u32

The index of the bin that this metadata corresponds to.

The GPU doesn’t use this, but the CPU does in order to perform the reverse mapping from bin metadata index back to the bin. We could store this in a non-GPU-accessible buffer, but I figured the extra complexity wasn’t worth it.

instance_count: u32

The number of mesh instances in this bin.
