Module depth 

Generation of hierarchical Z buffers for occlusion culling.

Currently, this module only supports generation of hierarchical Z buffers for occlusion culling.

Structs

DepthPyramidDummyTexture

Stores a placeholder texture that can be bound to a depth pyramid binding if no depth pyramid is needed.

DownsampleDepthPipeline

A single depth downsample pipeline.

DownsampleDepthPipelineKey

Uniquely identifies a configuration of the downsample depth shader.

DownsampleDepthPipelines

Stores all depth buffer downsampling pipelines.

ViewDepthPyramid

Stores a hierarchical Z-buffer for a view, which is a series of mipmaps useful for efficient occlusion culling.

ViewDownsampleDepthBindGroup

The bind group that we use to attach the depth buffer and depth pyramid for a view to the downsample_depth.wgsl shader.

Constants

DEPTH_PYRAMID_MIP_COUNT

The maximum number of mip levels that we can produce.

Functions

create_depth_pyramid_dummy_texture

Creates a placeholder texture that can be bound to a depth pyramid binding if no depth pyramid is needed.

create_downsample_depth_pipelines

Creates the DownsampleDepthPipelines if downsampling is supported on the current platform.

early_downsample_depth

Produces a hierarchical Z-buffer (depth pyramid) for occlusion culling.

init_depth_pyramid_dummy_texture

late_downsample_depth

Produces a hierarchical Z-buffer (depth pyramid) for occlusion culling.

prepare_downsample_depth_view_bind_groups

Creates the ViewDownsampleDepthBindGroups for all views with occlusion culling enabled.

prepare_view_depth_pyramids

Creates depth pyramids for views that have occlusion culling enabled.
