Class links.Graph3d.Camera

Camera The camera is mounted on a (virtual) camera arm. The camera arm can rotate The camera is always looking in the direction of the origin of the arm. This way, the camera always rotates around one fixed point, the location of the camera arm. Documentation: http://en.wikipedia.org/wiki/3D_projection
Defined in: graph3d.js.
