How long do you have to wait before the graininess has reliably become
unnoticeable? That's a question I need an answer to before I can use
any unbiased renderer for animation work. I need a renderer that won't
give me a picture unless the quality is consistent from one frame to the
next.
With scanline and ray-tracing renderers, there comes a specific point at
which the renderer is *done* with the image and is ready to render the
next image. Unbiased renderers are never really done; they just go
until the user decides the quality is good enough. Sure, the user may
be able to set the renderer to go only a certain amount of time, but
except for a very short clip, and only after rendering a couple of
frames in that clip, can the time required for each frame be predicted
with any meaningful reliability.

John
