DXProf

Posting this very nice tool here for a friend of mine.
DXProf injects itself into applications that use Direct X for rendering. It analyzes each draw call in every frame and displays performance statistics for those draw calls, overlaying it over... |

Screen Space Water
|
Just some recent screenshots from my new water rendering approach. The water is based on volumetric fog and no geometry is rendered for the water - it's a postprocess screen space effect. The method fits perfectly into my deferred shading render... |

ATI GLSL bug?

I'm having some rather "fun" problems making my application run on ATI hardware. I'm currently on a Vista laptop with a ATI Mobility X1600, and all the latest drivers. Now the problems...

Tried it but it doesn't do anything at all when I run it on a Windows 7 64bit machine, no window, no task or process shows up in the task manager. Website says it should work on a 64bit machine.
Strange, i... |

Rendering Water as a Post-process Effect

Great article!
It's actually the very same algorithm I used in one of my demos 1,5 years ago. :)

Nice images.
Have you seen this: http://artis.imag.fr/Publications/2006/BD06a/ ?
No, have not seen this. Interesting, but they don't use a screen space approach. Very impressive caustics! |

Thanks for the cool vids, particularly vid2 is quite convincing of displacement.
I think you've invented a very cool technique, it shares alot with parallax mapping (Iteration on a heightfield) but being deferre... |

Martin:
Obviously you won't get real displacement, but it adds depth to the waves - much more so than parallax mapping would. I'm also working on adding a shadow effect on the waves - I think this will make it look even better. |

Sorry, been busy today so havn't had a chance to reply until now..
Thanks for all your replies!

I wouldn't say it's competing with geometry displacement - it's just another approach.

@pilo:
Thanks! Sorry, no demo available at the moment.
@funkymunky:
Currently no realistic interaction, just dueling heightmaps :)

No, not parallax mapping..

ATI GLSL bug?

1. The error message maybe indicating something is wrong with the shader pair (VS, FS). I can't just say it is a driver bug because I don't see all of the code.Well, even this code didn't work:
