    To employ Computer Graphics (CG) technology in the production of CG holograms or similar applications where the generation of consecutive pictures with rotated viewing directions is demanded takes a lot of time and money. This paper presents a two-pass surface rendering method for fast creating such animated pictures from a single view image structure. Instead of generating display data for a single picture, the first pass program constructs a Position Oriented (PO) frame buffer that contains the information of control points on every order of visible surfaces. A display program of second pass manipulates the frame buffer structure to generate surface rendered pictures with spatial and perspective transforms. Experiments proved the method is effective to create high quality surface rendered images with rotation capability. Various usuful facilities for CAD visualization have also been developed within the technique. The improvements on memory consumption and picture quality are also discussed in this paper.
