  • METHOD AND APPARATUS FOR GENERATING SHADOW BY USING AN ADAPTIVE SHADOW VOLUME ALGORITHM
    Publication number: 20070165029
    Abstract: A method and apparatus for generating shadow by using an adaptive shadow volume algorithm are disclosed. By accumulating the number of Z pass and Z fail during shadow volume rendering, the performance can be improved by adaptively selecting the z pass algorithm or the z fail algorithm. Accordingly, one of the algorithms (z-pass or z-fail) with better performance is used as the shadow volume algorithm for next frame.
