| Abstract(in English) | Vitual Reality technology provides a new methodology for human interface with realistic sensation, and has been received growing attention in the fields of human interface, computer graphics and computer vision. Reality of the virtual space is realized by generating photorealistic views in real time with computer graphic technology. One of key issues for the real time view generation problem is how to represent and display the 3-D virtual space efficiently with adapting human vision sensitivity. In this paper, we propose a level and efficient approach for hierarchical modeling and view generation of the 3-D objects, in which the resolution of each level is determined according to the distance from the observer to the object based on the depth perception sensitivity of human vision. The object is then efficiently displayed with sufficient accuracy by selecting the appropriate level of the model based on the distance between the observer and the object. Experimental results demonstrate the efficiency and correctness of the propose approach. |
