Syntax

struct FCameraRectangle

Remarks

Struct containing:

camera information,
input device rays used to define the corners of a rectangle contained in a selection plane, the device ray screen positions could be used to change the selection behavior when dragging from the top right to bottom left or vice-versa

Variables

	Name	Description
bool	bIsInitialized
FViewCameraStat...	CameraState
FInputDeviceRay	RectangleEndRay	FInputDeviceRay represents a 3D ray created based on an input device.
FInputDeviceRay	RectangleStartRay
FRectangleInPla...	SelectionDomain

Functions

	Name	Description
FConvexVolum...	FrustumAsConvexVolume()
void	Initialize()	This function must be called before other member functions whenever camera state or start/end rays are updated.
bool	IsProjectedPointInRectangle ( const FVector& Point )	Return true if the given 3D geometry projected to the camera plane is inside or intersecting the rectangle, and false otherwise
bool	IsProjectedSegmentIntersectingRectangle ( const FVector& Endpoint1, const FVector& Endpoint2 )
FVector	OrthographicProjection ( const FPlane3& Plane, const FVector& Point )	Return the 3D point obtained by projecting the given 3D Point onto the given projection plane.
FVector	PerspectiveProjection ( const FPlane3& Plane, const FVector& Point )	Return the 3D point obtained by projecting the given 3D Point onto the given projection plane.
FVector2	Point3DToPointUV ( const FPlane3& Plane, const FVector& Point3DInPlane )	Given a 3D point lying in the given Plane, return the UV coordinates of the point expressed in the following a two dimensional parameterization of the given Plane:
FVector	PointUVToPoint3D ( const FPlane3& Plane, const FVector2& PointUV )	Given a 2D point in the UV space of the given Plane, return the coordinates of the 3D point lying in the Plane.
FRectangleIn...	ProjectSelectionDomain ( double OffsetFromCameraPlane )	The XY plane in front of the camera (so point projection/camera plane clipping is unnecessary)
