Hi ALL,
I have been using the "Turbulence" function to add noise to the color in the
media. But as we know turbulence is coherent in space. But to generate a
sequence of renderings (e.g. an explosion cloud evolving in time) a noise
function needs to be temporally coherent. Otherwise, if the same noise is
applied to a point at all the steps in time, then the animation will have
the classical "shower curtain effect" cited in literature. So, can anyone
please suggest if there is a way to generate such a noise in POVRAY,
somethings that looks spatially as well as temporally coherent?
Thanks in advance,
Maurya
