A need for advanced design tools has motivated the design and development of three new concepts in device input for 3D displays: 1) a 3D sketching environment using 2D perspective input techniques, 2) B-spline approximation of free-hand curves in 3D using a 3D input device and stereoscopic 3D output and 3) an interactive cuberille sculpting environment supporting rapid presentation and modification of 3D objects.
