For lighting simulation try http://www.radiance-online.org/
Actually, RADIANCE may be a bit of an overkill for this application. You can model a water surface with the MESH primitive (as I did for some test scenes), but it's quite a pain. In general, RADIANCE is quite difficult to use and has a substantial learning curve -- there is no GUI to guide you. I developed the photon mapping addon for RADIANCE some years back (http://www.ise.fhg.de/areas-of-business ... on-mapping
still hasn't made it into the main distro, AFAIK), and I found it pretty tough to get into -- your mileage may vary. Remember this is primarily a *lighting* simulation tool. For a more general renderer, you might want to check out POVray.
