Public Member Functions

virtual ezStatus AddRenderPasses (const ezViewData &viewData, const ezCamera &camera, ezRenderGraph &ref_graph, const ezArrayPtr< const ezRenderPipelinePinConnection > inputs, ezArrayPtr< ezRenderPipelinePinConnection > outputs) override
 Called by the render pipeline when this pass is active. The pass declares its render-graph passes and writes the resulting transient handles into the outputs array.
 
virtual ezStatus AddRenderPassesInactive (const ezViewData &viewData, const ezCamera &camera, ezRenderGraph &ref_graph, const ezArrayPtr< const ezRenderPipelinePinConnection > inputs, ezArrayPtr< ezRenderPipelinePinConnection > outputs) override
 Called by the render pipeline when this pass is inactive instead of AddRenderPasses. The default implementation does nothing; passes that produce outputs must override this and at minimum write the same output handles they would in AddRenderPasses (typically by adding a clear pass) so downstream passes still see a valid resource.

 Sets the name of the pass.

 returns the name of the pass.

Detailed Description

Render pass that computes screen-space ambient occlusion (SSAO).

Generates an ambient occlusion texture from the depth buffer. The effect darkens areas where geometry is close together, simulating indirect lighting occlusion. Supports distance-based fade-out and various quality parameters.

◆ AddRenderPasses()

ezStatus ezAOPass::AddRenderPasses ( const ezViewData &  viewData,
const ezCamera &  camera,
ezRenderGraph &  ref_graph,
const ezArrayPtr< const ezRenderPipelinePinConnection >  inputs,
ezArrayPtr< ezRenderPipelinePinConnection >  outputs 
)
overridevirtual

Called by the render pipeline when this pass is active. The pass declares its render-graph passes and writes the resulting transient handles into the outputs array.

Reimplemented from ezRenderPipelinePass.

◆ AddRenderPassesInactive()

ezStatus ezAOPass::AddRenderPassesInactive ( const ezViewData &  viewData,
const ezCamera &  camera,
ezRenderGraph &  ref_graph,
const ezArrayPtr< const ezRenderPipelinePinConnection >  inputs,
ezArrayPtr< ezRenderPipelinePinConnection >  outputs 
)
overridevirtual

Called by the render pipeline when this pass is inactive instead of AddRenderPasses. The default implementation does nothing; passes that produce outputs must override this and at minimum write the same output handles they would in AddRenderPasses (typically by adding a clear pass) so downstream passes still see a valid resource.

Reimplemented from ezRenderPipelinePass.

◆ Deserialize()

ezResult ezAOPass::Deserialize ( ezStreamReader &  inout_stream)
overridevirtual

Reimplemented from ezRenderPipelinePass.

◆ Serialize()

ezResult ezAOPass::Serialize ( ezStreamWriter &  inout_stream) const
overridevirtual
