PERSPECTIVE TRANSFORMER FOR THE STEREOMATRIX 3-D DISPLAY SYSTEM

摘要

STEREOMATRIX is a large screen interactive 3-D display system which presents computer-generated transparent "wire-frame" drawings stereoscopically. A 3-D cross called the cursor can be moved around in the viewing space by the observer by means of a joystick. This feature allows the observer to select a point in the viewing space for graphic manipulation and relay it to the computer space. He can also use the joystick to draw pictures in the 3-D viewing space. The perspective of the figure changes with observer movement in such a way that the figure appears to be stationary in space.
