Global photon map examples
Example 1: What is the photon map?
Example 2: Lights and photons
Example 2: Search distance, Max photons and Max density
Example 3: Photon bounces
Example 4: Convex hull area estimate
Example 5: Convert to irradiance map
Example 6: Combining the global photon map with the irradiance map
The photon map is a rough approximation of the illumination in the scene; it is computed by tracing the path of particles (photons) which are emitted by the lights in the scene and bouncing around when they hit objects. Here is a simple scene and a visualization of the photon map for it:
