Constructs a PostProcessingCompute pass.

Parameters

config	Renderer configuration.
outputFormat	Pixel format of the output render-target image.
compShaderName	Name of the compute shader (without extension).
data	Pointer to the per-subclass uniform payload.
dataSize	Size in bytes of that payload.
name	Debug label for the pass.

Returns the output image for a given frame so that downstream passes can use it as a texture.

Parameters

frameIndex

Current frame index.

Gets the image format used for the output buffer

Reimplemented in lysa::GTAOPass::getColorAttachmentFormat(), lysa::SSAOPass::getColorAttachmentFormat()

Returns the output image for a given frame so that downstream passes can use it as a render taregt.

Parameters

frameIndex

Current frame index.

Returns the compute shader name (used as identifier for add/remove).

Renders a post-processing that needs the scene data

Parameters

commandList	The command list to record rendering commands into
scene	The scene frame data
depthAttachment	The target depth attachment
frameIndex	Index of the current frame

Reimplemented in lysa::SSAOPass::render(), lysa::GTAOPass::render()

Dispatches the compute shader using color + depth attachments.

Parameters

commandList	Command list to record into.
colorAttachment	Input color render-target.
depthAttachment	Input depth render-target (may be nullptr).
frameIndex	Current frame index.

Reimplemented in lysa::BloomPass::render()

Dispatches the compute shader using the provided color attachment as input.

Parameters

commandList	Command list to record into.
colorAttachment	Input color render-target.
frameIndex	Current frame index.

Reimplemented in lysa::SMAAPass::render()

Recreates the output image to match the new extent.

Parameters

extent

New viewport dimensions.

Reimplemented from lysa::Renderpass::resize()
