ATI X600XT.

Separately, assuming I even get this working:

* The plane is incorrect. I need to change the axis (rotate on X 90 degrees) How do I do this?
* I need to make the plane go from (0,0) to (sizex, sizey) instead of increase the size in all directions. How do I do this?

Thanks.

Hi together,

I would like to use this very promising water shader in my Project. Can anybody upload the OpenGL (GLSL) version of the water shader please? The file has been deleted on the original link and I can't find it anywhere else. Unfortunately it's also not contained in IrrExt.

Anyways this is a very nice work.

whoah! this is really nice!
but what about transparecy? It looks too opaque in my eyes.... ^^*

Open first the included main.cpp file for more details. Hope this helps.

@jorgerosa: Thx for the link , i managed to download your code after a few more or less random clicks on that page (what language is this? ).
However, your main.cpp is unfotunately empty :

Code: Select all

 
#include <irrlicht.h>             // Declare Irrlicht
 
 
#include "CWaterSurface.h"        // For ocean effects.
#include "CWaterShader.h"         // For ocean effects.
// #include "CBloodEffect.h"
// #include "CBloodShader.h"
 
 
/// RESULT:
/// http://irrlicht.sourceforge.net/forum/viewtopic.php?f=9&t=39624&p=232219#p232219
 
 
 
int main(char ** args)
{
 
 
}
 

Anyways, your code looks very interesting, i will have to study it a while.

@smso: Thx to you also.
