A system, method and computer program are provided for a virtual three-dimensional workspace wherein a two-dimensional workplane has been created in which two-dimensional images of said three-dimensional objects are carried so that when the viewer or user navigates within the three-dimensional workspace to points in the workspace where certain three-dimensional objects are no longer visible or available in the workspace, the viewer or user may still interactively perform functions relative to the no longer visible three-dimensional objects through interaction with the respective two-dimensional images of the three-dimensional objects which are still available in the workplane which is unaffected by the navigation.
