Water surface simulation - Polyloop

EMC · 16th July 2005, 22:56

Does anyone know of any free/cheap programs for generating an animated mesh surface that acts like water (and that you can deform with models of buoys, ships and such)? Or failing that (and I was never really hopeful of finding one), any good techniques of faking it in Carrara?

You can try to fake the pushing of water with this low cost plug-in: Potentializer.

From
http://www.kawachi.zaq.ne.jp/kurozuka/akurodigital/

But you'll also have to facter in by hand through a particle system the water spray and "wake" behind the boat.

For the spray, you may consider using an alpha blended dot texture with this free plugin: SpritesForPE_Plugin_WIN:

From
http://www.associatedfx.com/plugins.html

The wake may be possible with the potentializer to, but applied to several deforming objects that move. You will have to experiment with that one or you can use Anything Grooves with an animated movie texture to deform the water surface in the form of the wake (and the pushing the water away from the boat effect too).

Probablly generated more questions than solutions with all that above, but let me know if you need more help.

EMC,
There is a really good way of showing any sort of fluid simulation. The programm is called Real Flow 3. Its the top notch lquid simulator, but its not cheap it usally comes around $1,000 to $1,500 dolloars. If you really need a fluid simiulator I would buy it but if your buget is not that high then I would consider try finding some way to fake it in Carrara.

Realflow 3 website- www.nextlimit.com

I would say thatRealflow 3 sets the benchmark for power and controllability for fluid-simulating systems, but at a price.

Best of Luck,

Hi ,It's an old tuto (made with carrara3) but I did it in english too.
if I may :check it .
but again ,there is more than one way to fake the sea

Oh ! I forgot
You may use the caustic generator
There is many use for this good little program ,at least in the shader tree

Piem, thanks for the ideas... I did a little playing with AnythingGrooves (attached are the results (the animation looks better)). The one nice thing about making the water surface deformed with AG is that I can fade the waves out on the edges and put an infinite plane beneath the deformed plane with a matching bump-mapped version of the wave pattern. I didn't give the wave deformed a close enough look though - I'll have to do that.

The remaining problem is bow wave and wake, but that might be alleviated some by good choice of camera angle.

Check out rustboy.com
In the "movies" section it's movie #4
One of the more impressive water simulations I've seen.
He also gives a rough idea of how he accomplished the effect.
It's awesome.

I beleive blender recently added a liquid engine. not sure how well it works, though, or if you wanted to stay in carrarra.
@EMC-I hate to say this, but the sea needs a lot of work. It looks too regular and stiff.
