hey, all
I'm sure you've learned in your OW course, and probably through normal sea activity that different colors are absorbed by the water as you go deeper, giving the ocean its blue color. You may have learned that the reds go first, then orange etc, becoming pretty much pure blue at around 80-100ft.

Well, I'm in the process of creating an effect that simulates this change in color, based on scientific measurements. It's still in its infancy, but it's at the point where you can see it in action.

I still haven't figured out how to get the thing to no maximize the image to full window, so you need to manually resize the browser window to make the photo smaller. Anyhow, it's set to keep going deeper and deeper, 'till you close the window. And sorry, there's no indication of the depth simulated depth. The picture I'm using isn't such a good example, especially since the sky is already blue, and it looks strange adding blue to something already close to pure blue.

But trust your eyes. I'm sure the experienced can get a rough estimate from the hue of the blue. Actually that was one of the surprising things about this experiment, was that us divers are extremely sensitive to the changes in the hue of blue.

Right now, the model uses a dataset that represents water from deep (probably 200+ft) ocean, so it doesn't get as green-ish as a reef would.

This one simulates a visually "interesting" manmade lagoon in the keys. This one I just made from memory. For those who know, it should bring back sweet memories of training at Jules.

Anyway, I'm hoping to put in a "upload your own photo" feature, so you can check out how your new SUV would look 60ft under water, or check out how your new wetsuit would look at 300ft depth. But even as it is right now.. pay close attention to the color shift during the first few seconds. You can almost hear the splash from when you enter the water. Also, feel your breathing slow down as the hues of blue changes.
 
Holy crap, my breathing did slow down! I didn't realize it till i read the last part of your post there. Kind of cool!
 
As they used to say back in the day.....

FAR OUT!
 
lol! I'll be working hard to make this a little more practical. Heh, but how practical can it be anyway eh? But it's just funny
 
:crafty: woh, thats pretty cool. That ship would be incredible to dive. we need another good wreck off florida, hehe
 
Great job!
How about simulating light intensity decrease in addition to color?
