Yeah its completly opaque. I set it up like this.

glEnable(GL_BLEND);
glBlendFunc(GL_SRC_ALPHA, GL_ONE);

Ok. You tell that glColor4f isn''t working. What arguments do you send to glColor4f ?
Also, is lighting enabled ?

Lighting is enabled. I even calculate the Normals of the water so the waves look real.
I send 0,0,1,0.5 to glColor4f;

-> glColor4f(0,0,1,0.5);

Do you have COLOR_MATERIAL enabled ? If not, that''s normal that your surface is not transparent. Because when lighting is enabled, glColor commands are ignored unless COLOR_MATERIAL is enabled.
When you call glEnable(GL_LIGHTING) you should add some lines :

glEnable(GL_LIGHTING);
glColorMaterial(GL_FRONT_AND_BACK, GL_AMBIENT_AND_DIFFUSE);
glEnable(GL_COLOR_MATERIAL);

thanks a lot...
=)

hmm... still not working

What kind of problems happen now ? still the same ? not transpanrent ?

You should try calling glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);

cool.. =) its working now. Big Thanks
