The newframework allows the rapid generation of sequences representing anyarbitrary path in a “view space” within an environment inwhich both the viewer and objects move. The global illumination isstored as time sequences of range-images at base locations that span theview space. We present algorithms for determining locations for thesebase images, and the time steps required to adequately capture theeffects of object motion. We also present algorithms for computing theglobal illumination in the base images that exploit spatial and temporalcoherence by considering direct and indirect illumination separately. Wediscuss an initial implementation using the new framework. Results andanalysis of our implementation demonstrate the effectiveness of theindividual phases of the approach; we conclude with an application ofthe complete framework to a complex environment that includes objectmotion 收起
