dc.description.abstract | A fast scan-line algorithm for a raster-scan graphics display is proposed based on an observation that a sequence of successive image frames in animation mostly consists of still objects with relatively few moving objects. In the proposed algorithm, successive images are generated using the background image composed of still objects only, and moving image composed only of moving objects. The color of each pixel in the successive images is then determined by one, which is nearer from eye, between the two candidate pixels, where one is from the background image and the other is from the moving image. The background image is generated once in the whole process, while the moving image is generated for each time frame using an interpolation of two images generated at the start and end time of the given time interval. For the purpose of fast shadow generation, we classify the shadows into three groups, i.e., still shadows generated by still objects on still objects, moving shadows generated by moving objects on still objects, and composite shadows generated by both still objects and moving objects on moving objects. These shadows can be generated very quickly by utilizing the frame coherence. According to the experimental results, a speed up factor of 3.2 to 12.8, depending on the percentage of the moving objects among all objects, was obtained using our algorithm, compared to the conventional scheme not utilizing the frame-to-frame image coherence. | - |
