#Ripples Help
I've been having trouble for the longest time trying to understand
how the various parameters which define the "Ripples" bump map affect
the appearance of the ripples. I think I've boiled it down to these
problems:
1. What is the "texture size" ? How is it related to "wavelength" ?
2. It appears that if you specify multiple sources, they all
originate from the the same point (texture center). Therefore,
how do you generate an interference pattern of multiple
reflections (such as in a pool with a random pattern of
ripples due to multiple reflections) ? I've done it before,
but I'm not sure what it was that did it.
3. Once you get a realistic interference pattern, how do you
specify a "wave speed" to make the ripple motion look natural?
Is it always, as the Lightwave 2.0 manual says, about one-tenth
of the wavelength ?
Thanks !
