Enum PreprocessWorkItemBuffers

pub enum PreprocessWorkItemBuffers {
    Direct(RawBufferVec<PreprocessWorkItem>),
    Indirect {
        indexed: RawBufferVec<PreprocessWorkItem>,
        non_indexed: RawBufferVec<PreprocessWorkItem>,
        gpu_occlusion_culling: Option<GpuOcclusionCullingWorkItemBuffers>,
    },
}

The buffer of GPU preprocessing work items for a single view.

Variants

Direct(RawBufferVec<PreprocessWorkItem>)

The work items we use if we aren’t using indirect drawing.

Because we don’t have to separate indexed from non-indexed meshes in direct mode, we only have a single buffer here.

Indirect

The buffer of work items we use if we are using indirect drawing.

We need to separate out indexed meshes from non-indexed meshes in this case because the indirect parameters for these two types of meshes have different sizes.

Fields

indexed: RawBufferVec<PreprocessWorkItem>

The buffer of work items corresponding to indexed meshes.

non_indexed: RawBufferVec<PreprocessWorkItem>

The buffer of work items corresponding to non-indexed meshes.

gpu_occlusion_culling: Option<GpuOcclusionCullingWorkItemBuffers>

The work item buffers we use when GPU occlusion culling is in use.

Implementations

impl PreprocessWorkItemBuffers

pub fn push(&mut self, indexed: bool, preprocess_work_item: PreprocessWorkItem)

Adds a new work item to the appropriate buffer.

indexed specifies whether the work item corresponds to an indexed mesh.

pub fn clear(&mut self)

Clears out the GPU work item buffers in preparation for a new frame.
