GetCustomRenderTargetSize ( const IDisplayClusterViewport* InViewport,
FIntPoint& OutRenderTargetSize
)

 This function can override the size of the RenderTarget texture for the viewport.
Public function Const const FString &

GetId ()

 Return projection policy instance ID
Public function Virtual UMeshComponent * Build preview Editable mesh This MeshComponent is a copy of the preview mesh and can be moved freely with the UI visualization.
Public function Virtual UMeshComponent *

GetOrCreatePreviewMeshComponent ( IDisplayClusterViewport* InViewport,
bool& bOutIsRootActorComponent
)

 Build preview mesh This MeshComponent cannot be moved freely.
Public function Virtual Const USceneComponent *const Return Origin point component used by this viewport This component is used to convert from the local DCRA space to the local projection policy space, which contains the calibrated geometry data used for the warp.
Public function Const const TMap< FString, FString > & Return projection policy configuration
Public function Virtual Const USceneComponent *const Return Origin point component used by preview Editable mesh

GetWarpBlendInterface ( TSharedPtr< IDisplayClusterWarpBlend, ESPMode::ThreadSafe >& OutWarpBlendInterface
)

 Return warpblend interface of this policy
Public function Virtual Const bool

GetWarpBlendInterface_RenderThread ( TSharedPtr< IDisplayClusterWarpBlend, ESPMode::ThreadSafe >& OutWarpBlendInterfaceProxy
)

 Return warpblend interface proxy of this policy
Public function Virtual Const IDisplayClusterWarpPolicy * Get warp policy
Public function Virtual Const IDisplayClusterWarpPolicy * Get warp policy on rendering thread
Public function Virtual void Called when current level is going to be closed (i.e. before loading a new map)
Public function Virtual bool Called each time a new game level starts
Public function Virtual bool Ask projection policy instance if it has any Editable mesh based preview
Public function Virtual bool Ask projection policy instance if it has any mesh based preview
Public function Virtual bool Ask projection policy instance if it has any mesh based preview

IsCameraProjectionVisible ( const FRotator& InViewRotation,
const FVector& InViewLocation,
const FMatrix& InProjectionMatrix
)

 Return true, if camera projection visible for this viewport geometry ICVFX Performance : if camera frame not visible on this node, disable render for this camera

IsConfigurationChanged ( const FDisplayClusterConfigurationProjection* InConfigurationProjectionPolicy
)

 Check projection policy settings changes
Public function Virtual bool Returns if a policy provides warp&blend feature

Public function Virtual Const bool Returns true if this policy supports ICVFX rendering
Public function Virtual Const bool Handle request for additional render targetable resource inside viewport api for projection policy.
Public function Virtual Const bool This function controls the RTT size multipliers - if false is returned, all modifiers should be ignored.
Public function Virtual Const bool Returns true if the policy supports input mip-textures.
Public function Virtual void Projection policy can override PP
Public function Virtual void Send projection policy game thread data to render thread proxy called once per frame from FDisplayClusterViewportManager::FinalizeNewFrame
