realistic oceans?

I have no working experience with any software or techniques to produce photorealistic seascapes. I am aware of Realflow and that it can be used with some of the more well-known all-around 3D softwares, such as 3DS Max.

I am also aware that half of the quality is a result of the user. However, I'd like to know if there are any suggestions on the software choices I can make that will give me the best potential for really super-real close-ups in the middle of a rough sea.

At the moment, 3DSMax and Realflow are what I'm thinking, but that's only because of what is written about a lot online. And, I have no idea about a superior renderer for this kind of thing. Stills only, by the way.

can you be more specific about what you want?

If it is merely a good looking ocean surface the maya has its Ocean Shader which can make good looking waves. If you need more detail the look into maya fluids or realflow.

If you need your water to interact with objects like some one splashing around or swimming then real flow would be a better solution. The downside of realflow is that to do a large amount of water will require a large amount of processing power.

A combination of the two is probably whats best, with realflow or maya fluids for the closest parts and maya Ocean for the background.

Thanks. That will steer me in the right direction, I'm sure. Here's a picture that has all the rough features I'd likely be trying to depict. I am particularly interested in getting some transparency to the peaks so you get that green glow effect. In other words I guess I mean I don't just want a flat shader solution for the surface, the water should be a volume.

You're asking for a software to be used? My first thought for ocean goes immediately to Houdini but I'm sure most app will have a way to do this.

Yes. I'm just wondering if a particular software(s) has more potential for ultra-realism than another, aside from user skill.

That video was A-1 Prime.

Well, there are many tools for this job, depending on the amount of time AND money you want to spent.

There's for example Thinkboxsoftware Krakatoa
But, i've seen some great oceans being created in Vue and even Blender as well.

You could certainly create an ocean surface with Realflow or another full fluid solver but if this is for a still, that's way overkill. If there won't be any collision interaction (splashing) from objects such as rocks or boats, then you don't need a fluid solver. Krakatoa could be used for rendering mist/foam/spray but again that's a bit much for one frame.

Some options for an ocean surface without fluids:

Maya Ocean (built in)

Houdini Ocean FX (built in)

HOT - An open source plugin that is very popular for ocean surfaces. It stands for "Houdini Ocean Tools" but there are versions of HOT for other apps as well (i.e. Maya, Max, Blender, Cinema 4D, etc). It's freely available online; you'll have to look for the one that works with the app you want to use. Make sure you find a compiled one, as it's also available as source code (unless you want/need to compile it yourself for some reason).

The advantage of the above solutions over a fluid solver is that they don't need long fluid sims...they are geometry deformers (create grid, apply ocean deformer). You can get a very realistic ocean surface in seconds. Adding particle spray/foam/mist and shading/lighting it to look real will take a bit more work, but when it comes to seascapes, something like this is pretty much the standard.

Example (using Houdini Ocean FX):

You can try 3DSMax - Dreamscape plugin for the shot.

I think Blizzard used Dreamscape in this cinematic where is very similar shot of what you want:

If this is for a still image only, why do you need to go overkill and do complex ocean sims or build complicated shaders?

Just take photos of a real ocean, water splashes and foam, and/or buy stock photos. Stitch them together and tweak the picture in Photoshop until you have the exact effect you want.

Woohoo, OK, this seems like what I've been looking for!

You could also get nice and easy open oceans with a cheap version of Vue.

Do you have better examples of the same sort of scene, by any chance?

How about Storm Studios' work on Kon-Tiki? Here's their vfx breakdown reel: http://vimeo.com/48314160

There's more material on Side Effects Software's customer story for Storm Studios and their usage of Houdini on Kon-Tiki: http://www.sidefx.com/index.php?opt...=2263&Itemid=68
