public class TLcdPerspectiveProjection extends ALcdProjection
TLcdGeneralPerspective
, this
implementation uses different input parameters and does not impose
restrictions on the 3D position of the camera. Also, the origin of the
projection plane always coincides with the principal point.TLcdGeneralPerspective
