awesomeness...
this is spectacular work Captain Hannes!!  :D

the foam & displaced sails are great breakthroughs.
WARNING! WIZARDS! DO NOT PREDICT THE BEHAVIOR OF OTTERS UNLESS YOU OBEY BIG HAPPY TOES.

OK, since the deadline is set to August 14th, there's plenty of time for nitpicking ;D!
Here is a test animation in final quality to show the displacement of the sails. I left out the water, the terrain and the palmtrees to speed up rendering. The flickering is way better in this quality, but nevertheless I used frameblending which eliminates the flickering almost completely.

That looks surprisingly realistic. Nice work. I take it you can't use Raytrace Object Rendering with this though?

Unfortunately not. It destroys the sails displacement and the terrain.
Btw here is a (crop rendered) test animation of the bow wave with high quality settings except RTE is on and AA set to 2. One frame took 12 minutes to render. Without RTE it would have been more than 2 hours! The first part is original, the second part with frame blending.

Of course the crop render area is resized.

I'll make another test animation with RTE on to see how much the terrain and the sails will be affected.

Hannes

So this is how it looks with RTE on, AA 2. Rendertime about 32 minutes instead of more than 9 hours. Not too bad!
But look at the ship, especially the sails. Terrible! The rest is OK, so isn't there a way to raytrace everything EXCEPT the ship? HELP!!!

Oshyan

Currently there is no way to selectively raytrace, but I agree it would be a very useful feature. I think there could be some additional tuning here though that would maintain reasonable render times and still increase quality. Generally speaking don't worry about that, it's something I'll have to tackle if your entry ends up winning.

By the way the frame blended version really does look much better, quite good in fact. What app are you doing the blending in?

- Oshyan

Hannes

It's Combustion. I used a Timewarp operator. Method: Trail, 2 samples each. It's really great to reduce flickering (I found this trick somewhere in the internet. Don't remember where).

Oshyan

Ah, I don't have Combustion. :D I wonder if VirtualDub's Temporal Smoother filter would work though...

Hannes

It works. But it doesn't look that good. As you can see in the last part, it looks like jpg artifacts, somehow blurred and dirty. I had to use this effect in VD with 75%, otherwise the flickering was still there.

Your project is very nice coming  :)

You may know these filters for Virtualdub and AviSynth by MSU Video Group !
There are many very good filters . Did you tested the Deflicker filter there , Hannes ?

Hannes

Oh thanks for the tip, Kadri! I immediately tested it. Well, there's some obvious ghosting when using the blend mode, and the flicker is still there. Thanks anyway!!!

Don't worry, it's not my main problem. The biggest one is rendertimes.
At the moment I am still rendering another test animation of the sails with RTE on. Without it I had to use a value of 250 for the displacement of the sails. After some testing I found that I had to use a very much lower value for the displacement (0.5 - unfortunately only bump with RTE on). I'll see how the sails will turn out with just bump mapping.

Here are many filters. But not all are for virtualdub ; when you click on them you will see if it will work or not with VD.

These filters are time wasters too sometimes. So i picked some of them . But i haven't used them all.
Begin from these ones if you want to try them . Some of them are in VD i think.
And be carefull if you want to try them . I didn't downloaded from these links!

Sometimes they work on one scene and on the other not unfortunately . And these are free ones .
They are not always better then the commercial ones you know :)

If you can use a frame doubler you can maybe cut the render time and the flicker with one stone(?) !
This is wishfull thinking of course , Hannes  :)
