[page:Object3D] →
[name]
Abstract base class for cameras. This class should always be inherited when you build a new camera.
Constructor
[name]()
Creates a new [name]. Note that this class is not intended to be called directly;
you probably want a [page:PerspectiveCamera] or [page:OrthographicCamera] instead.
Properties
See the base [page:Object3D] class for common properties.
[property:Boolean isCamera]
Used to check whether this or derived classes are cameras. Default is *true*.
You should not change this, as it used internally by the renderer for optimisation.
[property:Layers layers]
The [page:Layers layers] that the camera is a member of. This is an inherited
property from [page:Object3D].
Objects must share at least one layer with the camera to be seen
when the camera's viewpoint is rendered.
[property:Matrix4 matrixWorldInverse]
This is the inverse of matrixWorld. MatrixWorld contains the Matrix which has
the world transform of the Camera.
[property:Matrix4 projectionMatrix]
This is the matrix which contains the projection.
Methods
See the base [page:Object3D] class for common methods.
[method:Camera clone]( )
Return a new camera with the same properties as this one.
[method:Camera copy]( [param:Camera source] )
Copy the properties from the source camera into this one.
[method:Vector3 getWorldDirection]( [param:Vector3 target] )
[page:Vector3 target] — the result will be copied into this Vector3.
Returns a [page:Vector3] representing the world space direction in which the camera is looking.
(Note: A camera looks down its local, negative z-axis).
