public static class CameraUtils

The CameraUtils type exposes the following members.

Methods

	Name	Description
	CalculateCameraAngles(Vector3, CoordinateSystems, Single, Single)	Calculates heading and attitude angles in degrees from lookDirection as Vector3.
	CalculateCameraAngles(Vector3, Vector3, CoordinateSystems, Single, Single, Single)	Calculates heading, attitude and bank angles in degrees from lookDirection and upDirection as Vector3.
	CalculateCameraAnglesInRadians	Calculates heading and attitude angles in radians from lookDirection as Vector3.
	CalculateCameraDirections	Returns the lookDirection and upDirection from the specified heading, attitude and bank (angles in degrees).
	CalculateUpDirection	Calculates the up direction vector from look direction vector.
	GetClosestPathStartAngle	Returns an adjusted start angle so that the path to the end angle will be the shortest.
	GetCoordinateSystemInvertedTransformMatrix	Gets the inverted view transformation matrix for the specified coordinate system type.
	GetCoordinateSystemTransformMatrix	Gets the view transformation matrix for the specified coordinate system type.
	GetIntoTheScreenVector	Gets the vector that points into the screen (forward) for the specified coordinate system type.
	GetOrthographicScreenSize	GetOrthographicScreenSize calculates a size on screen (in same units as viewSize - without DPI scale) of a size in 3D space (worldSize) that is shown with orthographic camera with cameraWidth and in SceneView with viewSize.
	GetOrthographicWorldSize	GetOrthographicWorldSize calculates a size in 3D world from a screen size (screenSize in screen coordinates) that is at distanceFromCamera and shown with orthographic camera with cameraWidth and in SceneView with viewSize.
	GetPerspectiveScreenSize	GetPerspectiveScreenSize calculates a size on screen (in same units as viewSize - without DPI scale) of a size in 3D space (worldSize) that is at lookDirectionDistance and shown with perspective camera with fieldOfView and in SceneView with viewSize.
	GetPerspectiveWorldSize	GetPerspectiveWorldSize calculates a size in 3D world from a screen size (screenSize in screen coordinates) that is at lookDirectionDistance and shown with perspective camera with fieldOfView and in SceneView with viewSize.
	GetRightDirectionVector	Gets the right direction vector for the specified coordinate system type.
	GetUpVector	Gets the up vector for the specified coordinate system type.
	IsClockwiseRotation	Returns true if the shortest direction from startAngle to endAngle is in clockwise direction. The angles are specified in degrees.
	NormalizeAngleTo180	Returns an angle that is normalized so that it is always in range from -180 to 180 degrees. For example 270 is converted into -90; -200 is converted into 160. To get an angle in range from 0 to 360, use the NormalizeAngleTo360(Single) method.
	NormalizeAngleTo360	Returns an angle that is normalized so that it is always in range from 0 to 360 degrees. For example -90 is converted into 270; 400 is converted into 40. To get an angle in range from -180 to 180, use the NormalizeAngleTo180(Single) method.
	StrafeCamera	Returns a move vector that would strafe the camera - moves it in the direction perpendicular to the camera's LookDirection and UpDirection.
	StrafeCameraOnHorizontalPlane	Returns a move vector that would strafe the camera on the horizontal plane - moves it in the direction perpendicular to the camera's LookDirection and UpDirection.
