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.
• write_indirect_parameters_buffer
