Advanced Ocean Shader Demo (version2)

martinsh

I was tinkering with Cube Maps and found a displacement vertex shader in my old Blender demo archives.. and i had an idea to use it to make ocean waves. Im impressed by the speed of the vertex shader, with all the textures and stuff it runs ~400 fps.

There could be problems running this on ATI cards due fresnel thing.. so ill try to figure out how to fake the effect.

Woah!

Looks awesome!

torakunsama

I still don't get it!!! Why does it run so fast? Martinsh! You ARE AWOESOME!!! You are an inspiration for me !!
I'll use this, defenetly, does it work on spheres?

torakunsama

Yes! It Works on spheres!!! I'll finally be able to add more realistic oceans!!!

Moguri

Wow! Looks awesome!

I can't get the max fps, due to my graphics card not playing nice or something, but I still cap at 100fps!

OS: Windows 7 Beta
GFX: NVIDIA 8600m GT

Also, file uploading sites can be annoying, especially for a quick blend post. That's why pasteall.org now has a .blend uploader: http://pasteall.org/blend

How do you get such fps? I'm stuck at 60 fps, I'm using the standard version obviously.

and he did it again

Jorgie

Absolutely amazing!

It seems to work for me but for some reason I only get 1.217 fps

OS: Windows XP Home edition 2002 SP2
GPU: Geforce 7900 GS

Larryboy

75fps for me and thats only because its locked to the monitor frequency..

Absolutley awsome!

locadax

looks very cool

but on my 7600 gt (linux) is extremly slow only 1.5 fps

Hey thanks Moguri! ill keep the site bookmarked

I wish the Blenderartists forums allowed blend attachments little bigger than 976.6 KB.
3MB would be fine.

Yea i got same errors.. it still works though.

Edir: To see actual framerate, you have to disable V-Sync for Blender in NVIDIA Control Panel (dont know how to do it for ATI cards) and enable "Enable All Frames" in Blender.
