Detailed Description

FViewCameraState is a bucket of state information that a Tool might need to implement interactions that depend on the current scene view.

Member Function Documentation

Forward()

FVector FViewCameraState::Forward ( ) const

inline

Returns

forward camera direction

GetFOVAngleNormalizationFactor()

float FViewCameraState::GetFOVAngleNormalizationFactor ( ) const

inline

Returns

FOV normalization factor that should be applied when comparing angles

GetPDIScalingFactor()

float FViewCameraState::GetPDIScalingFactor ( ) const

inline

Returns

scaling factor that should be applied to PDI thickness/size

Right()

FVector FViewCameraState::Right ( ) const

inline

Returns

"right"/horizontal direction in camera plane

Up()

FVector FViewCameraState::Up ( ) const

inline

Returns

"up"/vertical direction in camera plane

Member Data Documentation

AspectRatio

float FViewCameraState::AspectRatio = 1

Current Aspect Ratio

bIsOrthographic

bool FViewCameraState::bIsOrthographic = false

Is current view an orthographic view

bIsVR

bool FViewCameraState::bIsVR = false

Is current view a VR view

DPIScale

double FViewCameraState::DPIScale = 1.0

DPI scale

HorizontalFOVDegrees

float FViewCameraState::HorizontalFOVDegrees = 90

Current Horizontal Field of View Angle in Degrees. Only relevant if bIsOrthographic is false.

Orientation

FQuat FViewCameraState::Orientation = FQuat(EForceInit::ForceInit)

Current camera/head orientation

OrthoWorldCoordinateWidth

float FViewCameraState::OrthoWorldCoordinateWidth = 100

Current width of viewport in world space coordinates. Only valid if bIsOrthographic is true.

Position

FVector FViewCameraState::Position = FVector(EForceInit::ForceInit)

Current camera/head position
