Abstract	Currently, the real time panoramic methods in modeling forest scene is mainly based on a single geometry volume. However, due to the limitation of view of cylindrical surface, distortion of spherical surface and accurate video camera orientation of cube surface, we can’t achieve the vivid scene. In this paper, we proposed a method of Comprehensive Dummy Volume Panorama (CDVP) using an irregular geometry surface composed of two hemispherical surface and one cylindrical surface. First,we construct hash function for Latitude-Longitude plotting and dissect panorama between panorama and dummy volume, and to construct θ-¿ link table of scene. Then, Inverse-Projection is used according to corresponding θ-¿ pieces to produce θ-¿ partial view. At last, local view coordinate was transformed to world view coordinate. This method implements 360° ramble and overcomes drawback of the current methods.
