High dynamic range rendering demo using OpenGL EXT_framebuffer_object extension

feature graphic

This demo of high dynamic range (HDR) rendering 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 glow effect.
