The line to intersect.
A point in world space, or undefined if the line does not
intersect with the near plane.
Returns whether this FrameCameraBase is an orthographic camera.
Returns whether this FrameCameraBase is a perspective camera.
Checks if the given point, in world space, is behind the near plane of the camera.
A point in world space.
true if the point is behind the camera.
Converts this FramePerspectiveCamera to a FrameOrthographicCamera using
the provided boundingBox to compute the viewing frustum.
The visible bounding box.
Returns a point on the near plane that intersects with
line. Iflinedoes not intersect, thenundefinedis returned.
