Re: sky shader and clouds

["Tim Leydecker" <BauerOink(at)gmx.de>]

In case it slipped attention, Zap also has put his testanimations
online  ftp://ftp.lysator.liu.se/~zap/skydemo.mov  In his own words:

"Observe this video that I made... it's basically a collection of all
test animations done during the development of the sun&sky.
Some are bad, some are worse, some are nice, some has bugs
in them, some use very low anti aliasing, and none is a peice of art.
However they do demonstrate the cloud feature..."

I don´t want to bash these in any way but I still wonder how
a sky shader can be used without having ways to reliably set
latitude, longitude and time of day registered to a custom North.

Also, there should be at least one complicated shot rendered
with production quality to prove a concept. I don´t want to
suggest Zap isn´t capable of doing that, he´s even an active
contributor to the cgtalk lighting challenges but I´m still sure
targeting productionquality results would serve development.
It´s not that I´d expect the highest level of production design
or complexity but real-world levels of meeting final image quality.

Just to make sure _it_is_working_correct. Not flickering or pumping...

Cheers

tim
