Tom Nuydens has been quiet for quite some time, but he's back and now with a great new HDR demo...
<blockquote>

I wrote a demo that does high dynamic range (HDR) rendering. It uses the EXT_framebuffer_object extension for its render-to-texture operations. The demo renders a scene into a floating point buffer, using a simple lighting model and some shadow mapping. The HDR portion of the image is then run through a separable gaussian blur filter and composited back onto the LDR portion, resulting in a fashionable-looking glow effect. You can get the demo right here. As usual, it may or may not run on anything other than a GeForce 6x00
