Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In computer graphics, spectral rendering is where a scene's light transport is modeled with real wavelengths. This process is typically a lot slower than traditional rendering, which renders the scene in its red, green, and blue components and then overlays the images. Spectral rendering is often used in ray tracing or photon mapping to more accurately simulate the scene, often for comparison with an actual photograph to test the rendering algorithm (as in a Cornell Box) or to simulate different portions of the electromagnetic spectrum for the purpose of scientific work. The images simulated are not necessarily more realistic appearing; however, when compared to a real image pixel for pixel, the result is often much closer.
