Figures 5 through 7 illustrate the MRT technique used to generate a high dynamic-
range scene. In the first rendering pass, three output buffers are created—a color 
map, a normal map, and a depth map. In the second pass, the lighting is calculated 
using the normal and depth map combined with lighting terms. Next, the scene is 
accurately lit with the color map.  
Finally, in the third pass, the superhigh-intensity light values that were outside the 0 
to 1 range are brought into the scene. The calculation involves blooming the pixels 
around areas of high-intensity pixels. The result of this pass is an incredible glow 
effect (Figure 7).
