Module mip_generation 

Downsampling of textures to produce mipmap levels.

This module implements variations on the AMD FidelityFX single-pass downsampling shader. It’s used for generating mipmaps for textures (MipGenerationJobs) and for creating hierarchical Z-buffers (the experimental::depth module).

See the documentation for MipGenerationJobs and experimental::depth for more information.

Modules

experimental

Experimental functionality related to mipmap generation.

Structs

DownsampleShaders

A resource that stores the shaders that perform downsampling.

DownsamplingConstants

Constants for the single-pass downsampling shader generated on the CPU and read on the GPU.

MipGenerationJobs

A render-world resource that stores a list of Images that will have mipmaps generated for them.

MipGenerationPhase

The list of Images that will have mipmaps generated for them during a specific phase.

MipGenerationPhaseId

Identifies a phase during which mipmaps will be generated for an image.

MipGenerationPipelines

Stores all render pipelines and bind groups associated with the mipmap generation shader.

MipGenerationPlugin

A plugin that allows Bevy to repeatedly downsample textures to create mipmaps.

Functions

can_combine_downsampling_bind_groups

Returns true if the current platform can use a single bind group for single-pass downsampling.

generate_mips_for_phase

Generates mipmaps for all images in a MipGenerationPhaseId.
