ABSTRACT:
Data containing the shape and motion of an object, the eye point and similar data is input to generate animation image data. For all frames, the motion of each image point is computed through utilization of data on the motion of the object and eye point used for producing the animation and, on the basis of the computed motion of the image point, spatio-temporal filtering is performed for anti-aliasing.
