Detailed Description

Encapsulates the data which is used to render a decal parallel to the game thread.

		UMaterialInterface *	InMaterial
	)

◆ FDeferredDecalProxy() [3/3]

Member Function Documentation

◆ GetBounds()

const FBoxSphereBounds & FDeferredDecalProxy::GetBounds ( ) const

inline

◆ InitializeFadingParameters()

void FDeferredDecalProxy::InitializeFadingParameters	(	float	AbsSpawnTime,
		float	FadeDuration,
		float	FadeStartDelay,
		float	FadeInDuration,
		float	FadeInStartDelay
	)

◆ IsShown()

bool FDeferredDecalProxy::IsShown ( const FSceneView * View ) const

Returns: True if the decal is visible in the given view.

◆ SetTransformIncludingDecalSize()

void FDeferredDecalProxy::SetTransformIncludingDecalSize	(	const FTransform &	InComponentToWorldIncludingDecalSize,
		const FBoxSphereBounds &	InBounds
	)

Updates the decal proxy's cached transform and bounds.

Parameters

InComponentToWorldIncludingDecalSize	- The new component-to-world transform including the DecalSize
InBounds	- The new world-space bounds including the DecalSize

Member Data Documentation

◆ Component

const USceneComponent* FDeferredDecalProxy::Component

Pointer back to the game thread owner component.

◆ ComponentTrans

FTransform FDeferredDecalProxy::ComponentTrans

Used to compute the projection matrix on the render thread side, includes the DecalSize

◆ DecalColor

FLinearColor FDeferredDecalProxy::DecalColor = FLinearColor::White

◆ DecalMaterial

UMaterialInterface* FDeferredDecalProxy::DecalMaterial

◆ FadeInStartDelayNormalized

float FDeferredDecalProxy::FadeInStartDelayNormalized

◆ FadeScreenSize

float FDeferredDecalProxy::FadeScreenSize

◆ FadeStartDelayNormalized

float FDeferredDecalProxy::FadeStartDelayNormalized

FadeT = saturate(1 - (AbsTime - FadeStartDelay - AbsSpawnTime) / FadeDuration)

refactored as muladd:
FadeT = saturate((AbsTime * -InvFadeDuration) + ((FadeStartDelay + AbsSpawnTime + FadeDuration) * InvFadeDuration))

◆ InvFadeDuration

float FDeferredDecalProxy::InvFadeDuration

◆ InvFadeInDuration

float FDeferredDecalProxy::InvFadeInDuration

◆ SortOrder

int32 FDeferredDecalProxy::SortOrder

Larger values draw later (on top).
