Hi

Some week ago I was searching for a hlsl shader which supports
both reflection and refraction.
the shader in the templates has some strange distortion if the camera moves close
It might be blind, but I didn't find any
I made my own now, using reflection and refraction.

If you have questions, you may email me at leor_hectometer@hotmail.com
or just pm me


a picture

here is the link
water shader download

note, the refraction uses some fresnel, so it can be hard to see some times

looking great

Just wondering , does this have things like ripple effects?

you should check out lerp()
and the fresnel isn´t very correct... You need to get use the pixelposition in worldspace (you will need more vertices for the water...) and I am pretty sure that you don´t have to convert the valuerange.
Other than that it looks very nice

thank you for the comments very much



I moved the pixelpositon stuff to the pixel, because this eliminates the distortion when you look at the water really close
I think you mean that?

Nope, I meant for calculating vecView. For calculating it you need the vertexposition in worldspace.

I will look at it, thanks

Can I have rapidshare download link please? The filefront link is not working for me, cant download anything from filefront.

Something you could add is specularity for the sun.
It is very easy to add but improves the look a lot You can check out a tutorialchapter about it here: http://www.riemers.net/eng/Tutorials/XNA/Csharp/Series4/Specular_highlights.php

normally you could use the out-coordinate of the vs for projecting, but then the effect you described occurs. I didn't find a way to stop the shader doing that.

I think you use tex2Dproj() for it...the problem is, that ps<2.0 don't support it.
