halo, I would like to ask is it possible to use openGL + C++ to produce the ripple effect? If yes, would anyone be kindly enough to give me some link ? Thanks.

Further, would they be any reference/sample source that teach the "dynamic reflection" ? (ie. when suddenly there is a butterfly on top of a lake, the surface of the lake can reflect it. thx)

It talks about reflection of a ball on the floor, I guess a butterfly on water is mostly the same ( except maybe if there's waves )

I could write a lot of stuff about that as I am actually doing it myself at the moment. Should I?

This is what my water looks like at the moment:

hi, will you create some ripple on the water? if so, what is the maths theorem you use?

This presentation was recently posted in the advanced forums. It might give you a good idea of how to do water:

Those posts were from 2004, so you might be better off making a new topic.
