Usually, the virtual scene is denoted by panoramas, it has three kinds: spherical panorama, cylinder panorama and cubic panorama. Firstly this paper discusses the environment map briefly. From our point of view, the theory of environment map is a footstone to building virtual environment. Then it presents the basic and speedup arithmetic of browsing the cubic panorama , and introduces an anti-aliased arithmetic of the environment image to eliminate the distortion of the image. At last, the paper implements a cubic panorama browser. The browser has functions as follow: roaming in any direction in the virtual environment and the display speed is in direct ratio to the speed of the mouse; cruising the virtual environment with zooming in or zooming out. The browser also provides anti-aliased functions in following situation: real-time anti-aliased function, actionless anti-aliased function and no anti-aliased function. The browser can make user get the biggest freedom and give a kind of convenient and natural interactive mode.Read More
