RenderZone Features - Final Gather

Final gather creates ambient light by distributing it non uniformly. It does this by calculating a single bounce of light in the scene. As a result, areas which are otherwise not reached by light directly are now illuminated. If one desires, a more accurate illumination can be calculated through radiosity, by allowing light to bounce more than once. Final gather will incorporate the extra illumination from radiosity together with light from advanced light types, such as environment and atmospheric lights to create illumination with a high degree of realism. It may be combined with ambient occlusion for images of the best quality.

Final gather and radiosity were used to compute multiple bounces of the sun and atmospheric light in the interior spaces.

Final Gather creates a dramatic effect of light pouring in from small exterior openings.
