High quality Anti Aliasing Reconstruction after applying a
render effect is only possible with the use of all sub pixel
information available from the renderer.
Every 3ds max conform renderer with full support of layered
G-Buffer channels can benefit of the immense render power of
finalDOF. Until now, a true Depth of Field rendering took several
minutes to render with a raytracer like finalRender or mental
ray and maybe it took days to render such effects with other renderers.
finalDOF on the other hand renders in near REALTIME and allows
interactive rendering of DOF and motion blur effects right from
within 3ds max.
