Struct IndirectParametersIndexed

#[repr(C)]
pub struct IndirectParametersIndexed {
    pub index_count: u32,
    pub instance_count: u32,
    pub first_index: u32,
    pub base_vertex: u32,
    pub first_instance: u32,
}

The wgpu indirect parameters structure that specifies a GPU draw command.

This is the variant for indexed meshes. We generate the instances of this structure in the build_indirect_params.wgsl compute shader.

Fields

index_count: u32

The number of indices that this mesh has.

instance_count: u32

The number of instances we are to draw.

first_index: u32

The offset of the first index for this mesh in the index buffer slab.

base_vertex: u32

The offset of the first vertex for this mesh in the vertex buffer slab.

first_instance: u32

The index of the first mesh instance in the MeshUniform buffer.
