Detailed Description

Functionality for fading in/out texture mip-levels.

Constructor & Destructor Documentation

FMipBiasFade()

FMipBiasFade::FMipBiasFade ( )

inline

Default constructor that sets all values to default (no mips).

Member Function Documentation

CalcMipBias()

float FMipBiasFade::CalcMipBias ( ) const

inline

Calculates the interpolated mip-bias based on the current time.

Returns

Interpolated mip-bias value

IsFading()

bool FMipBiasFade::IsFading ( ) const

inline

Checks whether the mip-bias is still interpolating.

Returns

true if the mip-bias is still interpolating

SetNewMipCount()

void FMipBiasFade::SetNewMipCount	(	float	ActualMipCount,
		float	TargetMipCount,
		double	LastRenderTime,
		EMipFadeSettings	FadeSetting
	)

Sets up a new interpolation target for the mip-bias.

Parameters

ActualMipCount	Number of mip-levels currently in memory
TargetMipCount	Number of mip-levels we're changing to
LastRenderTime	Timestamp when it was last rendered (FApp::CurrentTime time space)
FadeSetting	Which fade speed settings to use

Member Data Documentation

BiasOffset

float FMipBiasFade::BiasOffset

Difference between total texture mipcount and the starting mipcount for the fade.

MipCountDelta

float FMipBiasFade::MipCountDelta

Number of mip-levels to fade (negative if fading out / decreasing the mipcount).

MipCountFadingRate

float FMipBiasFade::MipCountFadingRate

Number of seconds to interpolate through all MipCountDelta (inverted).

StartTime

float FMipBiasFade::StartTime

Timestamp when the fade was started.

TotalMipCount

float FMipBiasFade::TotalMipCount

Number of mip-levels in the texture.
