Advanced Ocean Shader Demo (version2)

Game Engine Game Engine Resources
#1

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.

:eek:!!

Woah!

#4

Dam I can’t see it, got a ATI card :\

Looks awesome!

#5

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?

#6

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

#7

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

#8

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

#9

and he did it again :stuck_out_tongue: !

#10

Absolutely amazing!

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

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

#11

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

Absolutley awsome!

XP pro Intel E8400 3GHz, 4GB ram, Nvidia 8600 GT

#12

looks very cool :slight_smile: but on my 7600 gt (linux) is extremly slow only 1.5 fps :frowning:

and some info form terminal

Hey thanks Moguri! ill keep the site bookmarked :slight_smile:
I wish the Blenderartists forums allowed blend attachments little bigger than 976.6 KB.
3MB would be fine.
here you go:

Yea i got same errors… it still works though. :slight_smile:

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.

#15

Sadly only 2 fps for me

Win XP 32 bit sp 3
Xeon 3ghz and 3.25 gb of ram
Nvidia Quadro FX 550

#16

Not working on Ati9600xt - Solid white ocean…

#17

That’s incredible. It looks real.

#18

Wicked sick :slight_smile: Now I can finally see my true fps :slight_smile: Runs steady at 90 frames over here, but I get these weird artifacts .( Little white lines and dots. Are these the vertex shader errors?

#19

Looks very nice, but I guess I just found the limits of my GPU. :frowning:

NVIDIA GeForce Go 7600, 1.2 fps

#20

Wait what?! Then there is something wrong with your system… You should get atleast 20+ frames :frowning: I’ll check around see what I can dig up for you :wink:

Edit: I think you should get about 10 frames…hmm… I’ll check some more :slight_smile:
