Title: Ocean Water
Post by: rcallicotte on July 03, 2007, 04:27:36 pm
This might be useful as a start to a better look on water.

This includes the Water Shader.

Combined with some foam I think that this could look like some of the most realistic water I've seen from TG2 thus far.  Thanks for sharing!

Very nice for large rolling waves on a deep ocean!

Thats some nice water!

What I use for Ocean Effects..Is probably this kind of water:

I use this Type of water for Ocean, Because at where you want it you can make it at least "look" transparent for say near a shore...But if you want a more Deep look, all you need to do is make the water more reflective (that Pictuer is at a reflectivity of 2)

Enjoy!

After seeing the H2O reel from here, I've decided to wait to see what TG2 can really do when it's finished.   ;D

Wow, DD's EFX are one of the best in the industry. You won't compare a half finish software with that, do you?
Title: Re: Ocean Water
Post by: old_blaggard on August 27, 2007, 02:36:57 pm
Well, TG2 is based on some work that Matt did for Digital Domain back in the day.  I don't think TG2 has anything to do with the water system they're using there, though.

I must admit that water is very lovely. I still want to see waves crashing on a shore with spray some day.    :-[

Yes me as well, but Calico did do some awesome work around for ocean water for now, so that is a start and he did so very good also.  Great work if I never said anything before on the water Calico.

OK FYI guys......

The Terragen tgd2 Preview Monthly Challenges are open and offically up and running.  Go to the Contest area pages on Renderosity for Terragen and at the bottom of that page are the rules and Challenge giving the rules on how we plan to do the Monthly contests with Any, Rich and myself.  I think you all will find it very rewarding, a way to play wide open, and still have some structure to work in between, so get on it boys and girls as we need your support now that we are up and we have them running, not to mention all your help with advise and links to all these posts we have been doing and learning from.

OK see ya'll there guys and looking forward to all the fun we can have.  Also I will be working on PlanetSide to see if I can get them to anti up full versions of tgd2 for milestone Challenges that we can have as we go along. So your support is most important to get that part going, if they see allot of us doing stuff with tgd2, then I am sure the PR Dept will anti up goodies.  I have done this before when I was the Art, Music, sound and video Special group director for the NBMA (North Bay Multimedia Association) in the Bay area about 6 years ago and I am pretty sure I can get it worked out again with PS, with ya'lls help, meaning you all have to enter these things and get there interest going as well as ours.

I'm probably being a bit dim but the only contests I can find on renderosity specifically say you cant use Terragen technology preview. Could you possibly post a direct link to the relevant page?
Thanks
Richard
neverm,ind ~ found it. It was on the page showing
"Open Contests"
see more...
Title: Re: Ocean Water
Post by: DeathTwister on August 28, 2007, 03:35:37 pm
Sure its the main Contest page:
but you have to go all the way to the bottom to find it, so here is the link.
http://www.renderosity.com/mod/contest/index.php?contest_id=848 (http://www.renderosity.com/mod/contest/index.php?contest_id=848)

It is all the way at the bottom of the contest page in the Terragen section.  Not sure why it is all the way down there, but it is.  Let me know if you still can't get there, and the forum page for this months tgd2 Challenge is:
http://www.renderosity.com/mod/forumpro/showthread.php?thread_id=2710000 (http://www.renderosity.com/mod/forumpro/showthread.php?thread_id=2710000)
SO between the 2 you all should be able to get going, and the .ter file is on the page as well for you to grab and download.

I don't mind being hijacked (LOL), really, but it would be better to announce this from its own heading.  Eh?  This way everyone gets in on it. 

I've downloaded the file and am looking forward to it.  Thanks, DT.

Nice rolling waves! Here's a couple of ocean water images I tried a few months back...
Title: Re: Ocean Water
Post by: old_blaggard on August 28, 2007, 10:51:53 pm
Great detail on the first one!  The lighting and composition of the second looks very nice, although the water looks a little stretched.

Hay brother Calico,

  Actually if everyone could help spread the word that would be fantastic /smiles, and where are good places to post this about the Challenges besides where we have them? I am game to post more, if I know where to send them out.  Other then that I am just reminding peeps as I follow forum stuff, like this wonderful ocean water that you have created. So thanks Calico, you da Elf /winks.

dandelO,

Though I can see what o_b means about the stretching, you've done an excellent job on both scenes.  Do you want to share any node knowledge, TGCs, TGDs...?
Title: Re: Ocean Water
Post by: dandelO on August 29, 2007, 01:36:10 pm
Hi, sorry, I should have hunted down the .tgd's last night when I posted.
I think I've got one of them, the boat one, but both are created exactly the same way...

Just create a power fractal, break it's connection with the compute terrain node if you've created it via the terrain tab, plug it into the input of the water shader and set a massive feature scale level, between 50,000 to 100,000 is fine, adjust lead in scale etc to get a convincing wave effect, tweak til your hearts content!
If you want to create land in the scene too you'll need to create a new power fractal terrain and then set the displacement offsets of the water fractal accordingly, your water level will be very much higher than the land so give it some negative values in 1000m stages until your happy with the water level.

Here's a very basic tgd I just knocked together for demonstrative purposes and a clipfile of the water nodes on their own...
Title: Re: Ocean Water
Post by: rcallicotte on August 29, 2007, 01:46:06 pm
Thanks, dandel0!  I'll see if I can join this with the one I created to come up with something even better, if possible.
Title: Re: Ocean Water
Post by: DeathTwister on August 29, 2007, 03:34:40 pm
Wow thanks guys and yes I would love to see the .tgd and .tgc files on yours Calico if you have the time to post them after you play with them? That would be awesome.


Quick Model texturing Question:
Maybe should make this it's own Topic, but I am here now so...........
  Hay may I ask anyone if any of you all know how to say build more textures for a model that say has 40 textures to import in and since there is a 16 texture limit we cannot get those textures in and no way to go into the model tree and select each individual mesh to set a image map to, maybe we can if we know the textures that will be needed to bring them in first in a multi, image shader or maybe 4-to 10 if needed, and then assign them to the model somehow when you import them in? the model that is. I have some awesome stuff I have made and since sub=mapping is out in tgd2, more textures per mesh is our workaround to figure out.  Anyway if someone has that figured out? I sure would to know how you did it??????????? So will everyone else, including I am betting PlanetSide.  There must be a way, just have not had the time to mess around with it more then I have, bummer that that is.  It seems somehow to me and when I get time I was going to try this, but it seems like if we broke the multi shaders from the terrains and assigned them to the model and if we had all the right missing textures ion the multi shaders, it seems like they should kinda find the missing spots on the model? what ya think, anyone try that yet as a workaround? I know PlanetSide is working on it but has no ETA on it yet.

Here's another idea I've been kicking around whenever I've got nothing better to do...

I like to call this project "Look busy, here comes Moses!" ;)  :D

Trying to part the sea using 'kind of' the same method as I posted earlier.
The nodes are VERY messy just now, so I won't post them until they're cleaned up a bit and made into something resembling sense. :)
Title: Re: Ocean Water
Post by: rcallicotte on August 30, 2007, 08:20:54 am
Interesting idea.  It could really be cool.
Title: Re: Ocean Water
Post by: DeathTwister on August 30, 2007, 08:21:22 am
ROTFL good one /winks
Title: Re: Ocean Water
Post by: rcallicotte on August 30, 2007, 05:26:13 pm
Here is one color corrected (blue) and one straight from TG2 (green) created from the "final" ocean clip file.  While I probably won't visit this clip file again soon, anyone is welcome to update it and post their findings here.  If I find better means of doing this, I'll update the clip file as well.  This newest version has both the capability (though weak) of having steeper waves and has the ability to make foam.

Have fun.    :)
Title: Re: Ocean Water
Post by: old_blaggard on August 30, 2007, 06:26:44 pm
Frankly, I like the green better than the blue ;).  The surf looks a bit small, but the waves look promising.
Title: Re: Ocean Water
Post by: Saurav on August 30, 2007, 06:49:43 pm
I agree with o_b here, the waves are nice. The green one looks good for tropical waters.
Title: Re: Ocean Water
Post by: rcallicotte on August 30, 2007, 07:05:14 pm
Saurav and old_blaggard - The functions are adjustable.  I just threw together the wave and foam to do a picture and think you could pretty much do what you like...as long as TG2 can handle it.
Title: Re: Ocean Water
Post by: Volker Harun on August 30, 2007, 07:11:09 pm
The waves look very very good! Ireally need some time to check your shared files Calico!
It is a pity that I haven't yet.
Title: Re: Ocean Water
Post by: DeathTwister on August 31, 2007, 08:17:02 am
Wow Calico those are great, I am looking forward to playing with the files in a few days after my Company goes back home after our meetings.  Actually looks like the Blue is the Atlantic Ocean and the green one the Pacific Ocean, perfect.

Great, Calico! A fair bit more complicated than my effort. My brain isn't geared up enough and I've barely just started playing with the functions in T2.
I like to choose the easy way out and try and get just as good results my own way. This looks really great though, nice work!
Title: Re: Ocean Water
Post by: Volker Harun on September 04, 2007, 03:14:21 am
This is really good! I am glad that I gave it a try ... and it quite fast.

Is that compute terrain necessary? I do not think so ,-)
Title: Re: Ocean Water
Post by: rcallicotte on September 04, 2007, 09:34:07 am
It isn't?  Okay.  It seemed like I needed to recompute before going to the next stage of the node network.  Did you try it without the Compute Terrain?
Title: Re: Ocean Water
Post by: Volker Harun on September 04, 2007, 09:37:24 am
Yep - and I killed some other nodes ,-)
Title: Re: Ocean Water
Post by: rcallicotte on September 04, 2007, 11:15:10 am
Please repost your results.  I'm diddling around with it now and found that the Constant Scalars at the top can affect the amount of turbulence.  Lower numbers in both will produce bigger waves and higher numbers smooth out the ocean.
Title: Re: Ocean Water
Post by: Volker Harun on September 04, 2007, 11:40:17 am
At first, I changed the values of the constant scalars. I love odd numbers so I changed the second one to 499 and the first to 101 - just a feeling.
The Mix-Scalars produce the same values 0.5X + 0.5Z. So I deleted one of those nodes and on the other side an Exp Scalar node (just for fun).
Deleting these nodes did not seem to effect the result much.
Title: Re: Ocean Water
Post by: rcallicotte on September 04, 2007, 11:53:07 am
So did you remove the Sin Scalars above or below the Mix-Scalars?
