In a Virtual Reality based Computer-Aided Design (VR-CAD) system, the designer creates three-dimensional shapes using human–computer interaction (HCI) technique such as voice commands, hand motions, and finger motions. In this system, 3-D displays can provide the visual feedback to the designer a realistic graphical perception about the part she/he is designing. Especially, holographic method is particularly regarded as one of the most attractive approaches for creating the most authentic illusion of observing volumetric objects. Therefore, holographic 3-D display is the most suitable method for the VR-CAD system. Therefore, in this paper, we propose the fast generation method of 3-D hologram pattern using spatio-temporal redundant data of 3-D scene in VR-CAD system. Some experiments are carried out and its results are comparatively discussed with those of the conventional methods in terms of computational speed and required memory space.
