Fantasy 3D - The crimson’s sails

[damon579]

doesnt look bad at all, but has a heavy CG look, almost that of a really well done game.

[Grey]

I really like the image... but is it my imagination or did you render this without shadows?

[Anatoliy]

Thanks,

Now I made some changes in this image, the link left same

[Flypaper]

It's a nice piece, but here are my crits:

The sky has no effect on the ocean whatsoever. It's a pink sky and a blue/green ocean. Usually the sky color affects the water. The second thing is the trees in the upper left hand corner, they look way out of place, try texturing them a bit better.

The bottom cliff looks awsome, great texturing, but the side cliffs lack the same detail, has potential, but I don't think it's quite there yet.

[leigh]

Yes, to reiterate what Flypaper said:

- the sea gets it's colour from the sky, because of the reflection of water (Water itself has no real colour of it's own). So your water here will have to be changed to reflect the sky.

Also:
- the images you used to texture the cliffs have lighting in them. It looks like it was originally a photo. Try working the shadows out of the image before using it as a texture map ;)

Otherwise, a very nice image :)

[Anatoliy]

Thanks

The horizon line is too harsh. Try adding some fog in the far distance.

I disagree. Here's (http://www.naturephoto.com/html/008.htm) a real photo of an ocean at sunset. The sky is clearly golden orange, but the water is clearly deep blue. Here's (http://www.mikelevin.com/OceanSunset3.jpg) another.

Naturally, the highlights off of the waves need to fit the color of the sky, but ocean water normally absorbs the longer wavelengths and scatters the shorter ones more, giving a blue appearance.

i like the quality of the work, i cant do any critic since im not into the 3d yet
lots of scripting to do in flash :hmm:

[skeletor]

I rhink that the trailer on the cliff on the lower side on the picture shouldn't be that way. Rock dont dont look lay. You made it it like a trail on sand and grass should be.. .I hope I made it clear. . . anywaay... nice work :thumbsup:

It's the sky that scatters blue, and the ocean just reflects it.
Look at water - it is transparent. It therefore gets it's appearance from what is reflected on it's surface. Water has no colour. If you take ocean water and put it in a glass, it isn't blue, which is what you seem to be suggesting :shrug:.

The reason it appears blue here is because the sky directly overhead it is probably not as pink as on the horizon, and because the sun has dipped so low, the majority of the water is in shadow, therefore appearing darker, and blueish.

Particularly in the second photo - all the bits that are actually catching the light do have the pinkish tones. The other bits appear blue because they are in shadow.

Sure, sometimes sea water can appear to have a colour of it's own, but technically that is because of scattering from particles floating in the sea water - eg. grains of sand, and other sea debris. But as water is transparent, and therefore has no real diffusion properties, it cannot have a colour of it's own, as it cannot scatter colour wavelengths as such. The only way that sea water really affects lightwaves is to refract and reflect them.

Apart from that, the only way that water can actually be given a colour, is to dye it :)

[Das]

I think your argument is flawed.

"But as water is transparent, and therefore has no real diffusion properties, it cannot have a colour of it's own." Air is also transparent, yet the sky is blue. When you take samples large enough (the atmosphere, or the ocean), the particles make all the difference.

Here's a science link (http://kids.earth.nasa.gov/seawifs/ocean_color.htm) on Nasa's site.

A quote from that link:
"When we look at the ocean or observe it from space, we see that the ocean is blue because water absorbs red and reflects blue light. Using instruments that are more sensitive than the human eye, we can measure a wide array of blue shades, which reveal the presence of varying amounts of phytoplankton, sediments, and dissolved organic chemicals."

[leigh]

But that is EXACTLY what I am saying!
Water has no actual colour - the colour we see is because of stuff in the water - such as phytoplankton, sediments, and dissolved organic chemicals. That's what I am saying. I'm talking specifically about water here.
And if you read through my previous post, you will see that I spoke of this exact debris in water :)

[ToddD]

I think it looks pretty good, I don't care for the blurriness at the far end of the cliffs, it looks photoshopped as opposed to real DOF. Has great potential, I agrre with the prior crits, keep working on it!:beer:

[Das]

Hehe, found another link for ya:
here (http://www.birch.net/~lindabrown/000056.htm)

Anyway, my point was that ocean water often appears blue regardless of the sky color (although very shallow camera angles would give more sky reflectance, of course). The reason for the ocean being blue is kinda irrelevant to my original argument ;)

I found the link above pretty interesting, though. It (and a few others) are saying that pure, clear water is blue, although a very very faint blue.

Another site pointed out that when you fill a white swimming pool with pure water (before adding the chlorine treatment), the water will be light blue.

Very interesting, I did not know that!

[leigh]

Das - yeah, I was commenting on water in general, not situation-specific :)

Those are some really interesting points :D

Here is something I'm busy thinking about - perhaps the reason that these links talk about water being blue is because of the fact that water has oxygen in it, therefore you could say that there are tiny bubbles of air in it. Right?
So that would stand to reason that the reason it appears blue, is actually because of the air particles in it...
That's just a thought though, really :)

Also, looking at water can obviously make it appear blue, because you are looking at it through air, which is scattering light...

Hehehehe it's all so complicated :p

Interesting discussion indeed, but I doubt that Anatoliy want's his fantasy thread hijacked by a physics debate ;)It would be intersting to research this a bit further though, and post a thread on it in the Texturing forum...

[Das]

True. Sorry Anatoliy, for the thread hijack. I got interested in the science discussion. I'll just quietly Google to myself ... :)

I just had to check the link... near the horizon the orange sky is clearly bleding into the water and even on the foreground and generally all over the water there is a purple/violet tint (red+blue) and the highlights are a very pale orange

color rules! (or as we say around here "colour rules!")

:buttrock:

[Das]

I was refuting "the sea gets it's colour from the sky, because of the reflection of water (Water itself has no real colour of it's own). "

My point was that the ocean does have a real color of it's own (it's blue! .. or sometimes green! :) )

Obviously, since water at a shallow angle is reflective, it will also reflect the sky whenever the incident angle to the camera is shallow (part of every wave, and a whole lot near the horizon).

There are all sorts of interesting color interactions in the ocean. It was a lot of fun Googling some out. Try it; I bet just about anyone would find something they didn't know :)

[maximanya]

great!!!. I loved the sea. it is very realistic.:applause:

[Pegasus]

take a look at the perfet water.

AMAIZING...

So Leigh now are you trying to suggest that air is blue or what? oxygen is blue? You don't make sense. this critique has taken a wierd turn so I will start from scratch.

getting back to the very original post, it looks nice... I think it needs a little distance cue... that is, fog or atmoshphere and it would be a nice peice. colors are fine IMHO, I would tweak the lighting a bit.

[3Ants]

Hi~~~`guy!!!great!!!!!
good work.
But I think the cloud have any problem.
Do your best.

[Helix]

i love the pic, the cliffs' lighting seems funky, but it's surreall looking anyway cuz of the clouds.

my question: how did you do that great water w/foam?! what photos did you use and what method? has this been answered? cuz, dayum! :) nice work.

No, as I said earlier, air scatters light, which is why it appears blue. So it stands to reason that if there is air in water, perhaps those air bubbles scatter light too :shrug: Just a thought :)

[sanciok]

WHOOOO!!!!
Beautiful!
By the way i think leigh is right!!

[Anatoliy]

Thanks,

I use the photos only for texturing the cliffs. The water is the plane object with combination of gradients, noises, bumps and opacity. Splash – the plane objects with noise opacity.

Also I want say about color of the water – of course the water take the color from the sky and the my water has the crimson tone in far, but the color of the water depend on the wind-waves, time, placed the sun and – your forgot about it – the fog.
