Member Function Documentation

Compile()

void DiaphragmDOF::FPhysicalCocModel::Compile

(

const FViewInfo &

View

)

Compile the coc model from a view.

ComputeViewMaxBackgroundCocRadius()

FORCEINLINE float DiaphragmDOF::FPhysicalCocModel::ComputeViewMaxBackgroundCocRadius ( float  HorizontalResolution ) const

inline

Returns limit(SceneDepthToCocRadius) for SceneDepth -> Infinity.

ComputeViewMinForegroundCocRadius()

FORCEINLINE float DiaphragmDOF::FPhysicalCocModel::ComputeViewMinForegroundCocRadius ( float  HorizontalResolution ) const

inline

Returns limit(SceneDepthToCocRadius) for SceneDepth -> 0.

Note: this return negative or null value since this is foreground.

DepthToResCocRadius()

float DiaphragmDOF::FPhysicalCocModel::DepthToResCocRadius	(	float	SceneDepth,
		float	HorizontalResolution
	)		const

Returns the CocRadius in half res pixels for given scene depth (in world unit).

Notes: Matches Engine/Shaders/Private/DiaphragmDOF/Common.ush's SceneDepthToCocRadius().

GetLensRadius()

FVector2f DiaphragmDOF::FPhysicalCocModel::GetLensRadius

(

)

const

Returns the lens radius in unreal unit from which the path traced ray should be traced from.
