【Abstract】 This paper presents dynamic ray-tracing algorithms based on the related ray-tracing rules about dynamic visible regions, it抯 an algorithm originally devised to resolve the intricacy about the application of the ray-tracing algorithm to computer animation field. Dynamic ray-tracing algorithms include the ray-tracing algorithms for the visible regions of kinetic objects and the visible regions that can reflect or refract the kinetic objects that distributed in sequences of discrete points in time axis, and this paper presents two shading methods for the algorithms.更多还原
