When To Use

ICamera is used primarily to manipulate the perspective of a 3D display. It's implemented by the Camera associated with a SceneViewer.

Members

	Name	Description
	Apply	Applies camera parameters on rendering context.
	Azimuth	The polar azimuth of the observer relative to the target. When changed, the observer moves.
	CanSeeMBB	Indicates if the camera can see any portion of the given extent.
	CanSeeSphere	Indicates if the camera can see any portion of the given sphere.
	GetBackgroundColor	Returns transient background color.
	GetIdentifyRay	Returns the ray that corresponds to given screen coordinates.
	GetIdentifyVector	Returns the vector that corresponds to the given screen location.
	GetViewport	Returns the viewport screen coordinates.
	HTurnAround	Turns the camera horizontally around observer by the given azimuth angle.
	Inclination	The polar inclination of the observer relative to the target. When changed, the observer moves.
	IsUsable	Indicates if the camera has valid parameters.
	LevelObsToTarget	Levels the observer to the target.
	LevelTargetToObs	Levels the target to the observer.
	Move	Moves the camera in the specified direction. The distance is calculated by applying the given factor to the current viewing distance.
	MultiPhaseRendering	The state of multi-phase rendering. When true, the scene depth can be divided into multiple passes to improve rendering quality.
	Observer	The observer's position.
	OrthoViewingExtent	The extent visible by the camera in orthographic view.
	Pan	Moves both the observer and the target so that the object picked as the starting point on screen assumes the ending-point position.
	PolarUpdate	Updates the observer's location by given polar increments.
	ProjectionType	The type of projection.
	PropertiesChanged	Sets camera's dirty flag.
	QueryDistanceToMBB	Returns the distance to the given extent.
	QueryDistanceToSphere	Returns the distance to the given sphere.
	QueryDistanceToSphereCenter	Returns the distance to the given sphere's center.
	QueryIdentifyVector	Returns the vector that corresponds to given screen coordinates.
	QueryOrthoViewingPlatform	Returns orthographic projection viewing parameters corresponding to the given extent.
	QueryViewingPlatformMBB	Returns the viewing parameters corresponding to the given extent.
	QueryViewingPlatformSphere	Returns the viewing parameters corresponding to the given spherical extent.
	RecalcUp	Updates the up-vector.
	ReplayFrame	Renders a frame.
	RollAngle	The roll angle in degrees.
	Rotate	Rotates the observer horizontally around the target by a given angle in degrees.
	Scale	The orthographic projection scale.
	SetBackgroundColor	Sets transient background color.
	SetCoordOrigin	Adapts the camera to the internal coordinate system of scene graph.
	SetDefaultsMBB	Positions camera so that the entire given extent can be seen.
	SetDefaultsSphere	Positions camera so that the entire given spherical extent can be seen.
	SetViewport	Sets the viewport screen coordinates.
	Target	The target's position.
	UpDirection	The camera's up-vector.
	VerticalExaggeration	Adapts the camera to the scene's vertical exaggeration.
	ViewFieldAngle	The view-field angle in degrees.
	ViewingDistance	The viewing distance between the observer and the target. When changing, the observer moves.
	Zoom	Zooms in or out by moving the observer according to the required ratio between the new and previous viewing distances.
	ZoomToRect	Zooms to the given screen extent.
