Hello Hashers-
I was watching the "Secret of Kells" and saw some cool smoke effects which have me stumped.
They used celtic spirals for the rising smoke and the outer spiral lines changed from white to dark when they crossed some sort of masking line.(see animated clip).
I'm sure there is a pretty simple explanation how they achieved this effect..but I can't figure it out.
Can anyone explain this cool effect?
Many thanks,
Tom
