• Photon diffusion — refers to a situation where photons travel through a material with a high optical depth and very short mean free path. Their behavior is then dominated by scattering and the path of any given photon is effectively a random walk. A large ensemble… …   Wikipedia

• Photon mapping — In computer graphics, photon mapping is a two pass global illumination algorithm developed by Henrik Wann Jensen that solves the rendering equation. Rays from the light source and rays from the camera are traced independently until some… …   Wikipedia

• Photon gas — In physics, a photon gas is a gas like collection of photons, which has many of the same properties of a conventional gas like hydrogen or neon including pressure, temperature, and entropy. The most common example of a photon gas in equilibrium… …   Wikipedia
