Struct IndirectParametersCpuMetadata

#[repr(C)]
pub struct IndirectParametersCpuMetadata {
    pub base_output_index: u32,
    pub batch_set_index: u32,
}

A structure, initialized on CPU and read on GPU, that contains metadata about each batch.

Each batch will have one instance of this structure.

Fields

base_output_index: u32

The index of the first instance of this mesh in the array of MeshUniforms.

Note that this is the first output index in this batch. Since each instance of this structure refers to arbitrarily many instances, the MeshUniforms corresponding to this batch span the indices base_output_index..(base_output_index + instance_count).

batch_set_index: u32

The index of the batch set that this batch belongs to in the IndirectBatchSet buffer.

A batch set is a set of meshes that may be multi-drawn together. Multiple batches (and therefore multiple instances of IndirectParametersGpuMetadata structures) can be part of the same batch set.

Trait Implementations
