Syntax

public class BaseTargetRect3DCamera : BaseTargetPositionCamera

The BaseTargetRect3DCamera type exposes the following members.

Properties

	Name	Description
	AbsoluteDistance	Gets a distance from the camera to the Camera's target position - the value is an absolute value regardless of IsDistancePercent property.
	IsDistancePercent	Gets or sets a Boolean that specifies if the Distance property is specified in percentage or absolute value.
	IsDynamicTarget	Gets or sets a Boolean value that specifies if the Camera is constantly (CompositionTarget.Rendering event) monitoring the position and size of the TargetRect3D and move the camera according to the change.

Methods

	Name	Description
	BaseCreateFrom	This method is called from CreateFrom method and actually sets the properties on this camera. (Overrides SphericalCameraBaseCreateFrom(Camera))
	CheckTargetRect3D	Checks if TargetRect was changed - in this case update the camera
	ForceRefresh	Forces a refresh of the camera. (Overrides SphericalCameraForceRefresh)
	GetTargetRect3D	Gets the value of TargetRect3DProperty
	IsDynamicTargetPropertyChanged	IsDynamicTargetPropertyChanged
	SetCameraForTargetRect	Updates the TargetPosition based on the targetRect3D
	SetCameraPosition(ProjectionCamera)	Sets the camera position on cameraToUpdate based on the TargetPosition - overridden to use the IsDistancePercent property (Overrides BaseTargetPositionCameraSetCameraPosition(ProjectionCamera))
	SetCameraPosition(ProjectionCamera, Rect3D)	Sets the camera position on cameraToUpdate based on the targetRect as Rect3D
	SetTargetRect3D	Sets the value of TargetRect3DProperty
	TargetRect3DPropertyChanged	TargetRect3DPropertyChanged
	UnsubscribeRenderingEvent	Unsubscribe to Rendering event (Overrides BaseCameraUnsubscribeRenderingEvent)
	UpdateCamera	Updates the PerspectiveCamera (Overrides BaseTargetPositionCameraUpdateCamera(ProjectionCamera))

Fields

	Name	Description
	IsDistancePercentProperty	IsDistancePercentProperty
	IsDynamicTargetProperty	IsDynamicTargetProperty
	isTargetRectDirty	If true the targetRect3D was changed - the camera need to be updated
	TargetRect3DProperty	TargetRect3DProperty
