User Interface to a True 3-D Display Device

摘要

This thesis describes an interactive interface to a true three dimensional, real-dm dynamic graphic display, the TI Omniview. The system generates true 3-D images of volumetric data and objects. The TI Omniview is a cylindrical volumetric laser display that uses a rotating double-helix translucent disk to fill the display cylinder. Voxels are illuminated on the 2-D surface. The rotational speed of the disk allows the viewer to fuse the 2-D images into a true 3-D image. The interface provides the user with a quick and flexible means of manipulating the image generated, the sub-volume displayed, and the resulting 3-D image. The interface provides the user with the flexibility and convenience that a window, icon, mouse, and pointer graphical user interface provides to users of 2-D displays. Limitations of the device, however, do not allow the use of icons and pointers in the Omniview display. Instead a combination of voice commands, a joystick, and a 2-D menu system running on a host computer is used to provide the interface. This interface allows the user to select objects and scenes, but does not allow manipulation, such as rotation or placement, of individual objects....
