Functions

	Name	Description
void	ApplyWarpBlend_RenderThread ( FRHICommandListImmediate& RHICmdLi..., const IDisplayClusterViewportProxy ... )	Performs warp&blend.
void	BeginWarpBlend_RenderThread ( FRHICommandListImmediate& RHICmdLi..., const IDisplayClusterViewportProxy ... )	Initializing the projection policy logic for the current frame before applying warp blending.
bool	CalculateView ( IDisplayClusterViewport* InVie..., const uint32 InContextNum, FVector& InOutViewLocation, FRotator& InOutViewRotation, const FVector& ViewOffset, const float WorldToMeters, const float NCP, const float FCP )
void	EndWarpBlend_RenderThread ( FRHICommandListImmediate& RHICmdLi..., const IDisplayClusterViewportProxy ... )	Completing the projection policy logic for the current frame after applying warp blending.
const FStrin...	GetId()	Return projection policy name
UMeshCompone...	GetOrCreatePreviewMeshComponent ( IDisplayClusterViewport* InVie... )	Build preview mesh
const TMap< ...	GetParameters()	Return projection policy configuration
bool	GetProjectionMatrix ( IDisplayClusterViewport* InVie..., const uint32 InContextNum, FMatrix& OutPrjMatrix )
const FStrin...	GetTypeId()	Return projection policy type
void	HandleEndScene ( IDisplayClusterViewport* InVie... )	Called when current level is going to be closed (i.e. before loading a new map)
bool	HandleStartScene ( IDisplayClusterViewport* InVie... )	Called each time a new game level starts
bool	HasPreviewMesh()	Ask projection policy instance if it has any mesh based preview
bool	IsCameraProjectionVisible ( const FRotator& InViewRotation, const FVector& InViewLocation, const FMatrix& InProjectionMatrix )	Return true, if camera projection visible for this viewport geometry ICVFX Perforamance : if camera frame not visible on this node, disable render for this camera
bool	IsConfigurationChanged ( const FDisplayClusterConfigurationP... )	Check projection policy settings changes
bool	IsWarpBlendSupported()	Returns if a policy provides warp&blend feature
bool	ShouldSupportICVFX()	This policy can support ICVFX rendering.
bool	ShouldUseAdditionalTargetableResource()	Handle request for additional render targetable resource inside viewport api for projection policy.
bool	ShouldUseSourceTextureWithMips()	Returns true if the policy supports input mip-textures.
void	UpdateProxyData ( IDisplayClusterViewport* InVie... )	Send projection policy game thread data to render thread proxy called once per frame from FDisplayClusterViewportManager::FinalizeNewFrame
