Water Demo - Now OpenGL and DX supported

[BlindSide]

Hey I made a demo for a water shader. It is slightly based off the old one by omaremad, DeusXL and sio2. But I added a few things like:

- Fresnel.
- Bumpmapping.
- Sun/Specular effect.
- Underwater caustics.
- Shallow water colour (Water shader reads from heightmap file).

NOTE: This new version includes both DX and OpenGL, newer NVidia cards experiencing trouble with OpenGL version should try Direct3D9.

PS: It would be cool if you can test with other (129x129) heightmap files and see what kinda of colouring effects there are in the water from this.

Cheers

My current computer can't run it cause of my radeon 9200 but the screenshots looks great. Maybe you can post some more?

Hi Blindside!

The output seem to have problems here. The framerate is also very low (around 70 FPS) (Probably due to the errors rendering this.)

I see only the underwater texture and "some beach". The main water texture is not displayed.

Got this from the console:

Is this the water shader you were talking about on the channel.

Does it use clipping planes? And also, just curious, are you going to try implementing the ability to go under water?

[master123467]

Hmm well it wont work on my 256mb Nvidia FX5200

[DGENXP]

Hi

Works Fine on my machine - no problem

I must say, this is quite a shader you have here. A little bit of constructive critisism though, maybe you could make it a little more wavey as i think this would make it look great.. But what do i know I could never make something like this due to my lack of understanding on Pixel shaders

really good m8 keep it up

BTW will you be releasing the code for this i would much like to study it closer - For my own understanding really.

Spec:

AMD ATHLON 64 DUAL CORE 4200+
Geforce 7600GS
1024MB DDRII Ram
500GB HDD
WINXP HOME

*Halifax's question answered. O.O

That underwater water looks so awesome!

I don't intend any disrespect. But do you intend on making this look more realistic like Realistic Water Scene Node.

[BlindSide]

Yeah I am always improving it, I have only just started, and I will fix all the bugs, sorry about those. Source code will come once all bugs are fixed. I was using clipping planes until I realised they dont work on objects that have shaders applied to them, so I just faked em in the shader.

PS: Thank you for posting error messages!, christianclavet and master123467, this will help me greatly.

UPDATE: Ive fixed ATI errors (I hope.), same download link.

Hmm well it wont work on my 256mb Nvidia FX5200

Same card with yours...

[BlindSide]

All I can see is warnings, can you please paste the full error output so I can see the errors and such? Thanks
EDIT: Oh wait, is it the same thing as christian's?

[andrei25ni]

I'm getting the same result as Virion and christianclavet

[christianclavet]

Hi, Blindside.

Yes, I think it's the same. I had the same output on my screen.

I've updated all my drivers and DirectX. My computer can play the Crysis demo without any glitches.

[Halifax]

Very nice, very nice. Now it compiles with no errors or anything on my ATI Raedon XPRESS 200M. I also saw no artifacts after looking at it from every angle. The only thing that sucks is it takes a some time for the refections to update compared to the terrain, so they look offset when I move the camera. But that is because my graphics card sucks, and only runs it at 9 FPS.

[Virion]

All I can see is warnings, can you please paste the full error output so I can see the errors and such? Thanks
EDIT: Oh wait, is it the same thing as christian's?

Yes, same error with him. Is it because our cards do not support the features?

[BlindSide]

I'm not sure, I thought I had fixed it earlier (When I fixed the ATI errors.). You do not have the same cards but you do have the same drivers. The shader compiler is part of the drivers not the card itself. If you can post me the driver version I will update to this version and try to fix it on my Nvidia card.

EDIT: Actually I will just use the latest drivers because thats what christian is using.
