Oceans and Seas in Sketchup?

Or you can use something like this (there's also a free version if you do not mind that watermark)

Thanks
I think that's a very realistic SU solution.

Well, what you came up with sure looks great!

Thanks for your replies! The only drawback with this method is that you lose detail from the bmp image as you smooth the geometry. With bigger waves the mesh tends to create jagged peeks so smoothing is necessary unless a higher resolution bmp is used which greatly increases triangle count. I'm still liking the results I'm getting so far.
@notareal: Yeah, read about that. Saw some work arounds but never tried yet. I did some tests in Kerkythea by using photon map caustics and I see a difference. The water looks more realistic and I do see some subtle shadow effects on the river bed during the irradiance calculation. This is probably because the surface is a mesh displaced and not simply a flat surface with a bump map applied. But with calm water in a swimming pool I get what you're saying.
@Gaieus: That looks really cool.
I found some water textures from http://texturelib.com/#!/category/?path=/Textures/water/water
Here are 2 more renders using a texture from above site.
This is a semi-calm one with a bitmap at 100x75 pixels
This one is more turbulent with photon map caustics and I raised bitmap resolution up to 150x113 pixels.
I forgot to mention that during the Bitmap2mesh operation, the height of the waves also depend on the height set on the blue axis. A shallower height would make calmer water. The calmer image in this post was set lower than the second more turbulent one. I forgot the heights but will get into the habit of making notes.Using images from real waves looks a lot more convincing. I tweaked them in PS before applying. To solve the small detail problem (the smaller ripples on the bigger waves) I am trying to apply a bump map texture to the glass in Kerkythea but for some reason the bump from the image is not showing up. I applied a bump map to a flat plane and it showed just fine. It's a head scratcher. To be continued....

What is your smoothing method? Do you mean with Artisan?

Yes, I use Artisan to smooth the geometry. Just one pass is good enough. It's not necessary on calm water. I did not smooth the water meshes in first 2 renders in this thread. I only had to do it with the last one in my previous post where some of the peaks had more height. So it's not something that must be done every time.

Do you have a wireframe view of that model? Would be interesting to see.

Here ya go...
After making the water mesh, I then made it into a component and copied 2 times. I flipped the second mesh so the waves line up to avoid seeing a seam in the render. Was a bit scared to make a mesh on a very large scale at one time.
It looks worse than it actually is. The meshes took seconds to create on my 4 year old Q6600 Quad core.

I'm following this with interest. A really nice method and results. Thanks for sharing.

Is the difference between wireframe 2 and wireframe 3 an intersection opertion? Then smoothing of the results?@Gaius
Whose guitar music is that??? Super music. -
