Colour Plate 10 Efficient Radiosity in Dynamic Environments Page 327-336

Dynamic links events for an orthogonal gutter being approached by a patch. The links (in pink) are to the centre of the relevant hierarchy element. Links to the patch are dynamic, others are static. In the first frame many links go to the centre of the patch (to hierarchy element). As the patch gets closer to the gutter, links are demoted and move to the lower hierarchy levels.

Right: Dynamic links reinspected at each step. In far right column links and form factors are extrapolated up to seven frames ahead to predict events.
