Hi Marco,

a quick note …

> A true photorealism involves a biased rendering engine

I think you mean unbiased.

BTW. The term photorealism was coined long ago, before
modern biased and unbiased render engines saw their light.

I remember very well CGI stuff from the mid 80's which was
named photoreal too. I still have that on VHS tapes! :-)
If you would compare such footage with today standards you
would not agree that this is also photorealism.

A quick Wikipedia look-up for photorealism and non-photorealism
might help.

O.K. back to work … let our creative juices flow and i will end
this discussion now too. :-)

Best regards
Stefan
