Default New Demo: Heat Haze

This demo written in OpenGL simulates a heat haze effect through several render to texture passes and a set of GLSL shaders and ARB programs.

It defaults to FBOs to do the offscreen rendering, however if your current driver doesn't support them, there is a fall back to using the good old glCopyTexImage2D function.

Enjoy

Looks really good, especially when zoomed out.

Edit: Also, the screenshots don't do it justice. Running, it looks very realistic.

Very glad your "picky" driver didn't complain this time around
BTW in a previous thread, you mentioned that Stained Shadows won't work on your machine, correct? If so, are you still interested in running it? I might convert the High level shaders into regular assembly which will load faster and will most definitely run on any set of DX9.0 drivers.

Actually, I started using the 76.44s again since all the demos work well with them.

May be I'm wrong, but I guess this demo looks very similar to http://frustum.org/3d/index.php?demo=19

So? They both look like they're using the skull from the DX9 sdk so what's your point?

If you check the Fx composer utility on the nvidia website, you'll also see they have demos using the same skull.

Yup, as far as I can see we both use the same skull model and that's as far as similarity gets.

I came up with the heat haze algorithm and shaders on my own, the marble texture was found using a google search "marble texture".

Fixed an annoying bug that showed up on ATI boards and improved the flames look a lot

Did you change the color of the marble texture also?
