Module gpu_preprocessing

Batching functionality when GPU preprocessing is in use.

Structs

BatchedInstanceBuffers

The GPU buffers holding the data needed to render batches.

BatchingPlugin

IndirectParameters

The wgpu indirect parameters structure.

IndirectParametersBuffer

The buffer containing the list of IndirectParameters, for draw commands.

PreprocessWorkItem

One invocation of the preprocessing shader: i.e. one mesh instance in a view.

PreprocessWorkItemBuffer

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

Enums

GpuPreprocessingSupport

Records whether GPU preprocessing and/or GPU culling are supported on the device.

Functions

batch_and_prepare_binned_render_phase

Creates batches for a render phase that uses bins.

batch_and_prepare_sorted_render_phase

Batch the items in a sorted render phase, when GPU instance buffer building is in use. This means comparing metadata needed to draw each phase item and trying to combine the draws into a batch.

clear_batched_gpu_instance_buffers

A system that runs early in extraction and clears out all the BatchedInstanceBuffers for the frame.

delete_old_work_item_buffers

A system that removes GPU preprocessing work item buffers that correspond to deleted ViewTargets.

write_batched_instance_buffers

A system that writes all instance buffers to the GPU.
