- dahart 10y agoSure! I'm not sure the complete thesis with the renaissance geometry images is online anywhere, but it's mostly an expanded version of this paper: http://www.graphics.cornell.edu/pubs/1999/HDG99.html http://www.graphics.cornell.edu/pubs/1999/HDG99.html This is old now, and modern techniques have mostly surpassed it, but the basic idea was to combine single-sample ray casting for finding occluders probabilistically with an image-plane flood-fill using analytic methods to render the shadows. It's a way to only pay for accurate shadow calculations where shadows actually exist, and skip the shadow calculations in all the un-occluded areas.
