Watch what happens as you move around the spheres and the light under all three rendering modes: (1) standard ray tracing, (2) ray tracing with photon mapping, and (3) visualization of the photon map itself. Use keys 1, 2, and 3 on your keyboard to switch modes. The goal here was to implement ray tracing with photon mapping as simply as possible.

Global Illumination – Ray Tracing and Photon Mapping
https://denoofa.com/global-illumination-ray-tracing-and-photon-mapping/
Photon mapping is a concept originally introduced by Jensen (1996) and refers to a two-pass method of global illumination that traces illumination paths from both the light and the viewpoint. In the first pass, photons emitted from light sources are traced and cached in a data structure known as the photon map.

Photon mapping. When light reaches a surface, it will bounce or get transmitted in a way that is dependent on the surface: given an incoming light direction and wave length, it is possible to determine the amount of light received in any outgoing direction. ... This makes ray tracing limited in the images it can produce. Any effect that ...

Photon mapping is a global illumination technique to render scenes with some accurate lighting quickly. This method takes longer than vanilla ray tracing but is much less resource intensive than traditional Monte Carlo Ray Tracing. Monte Carlo ray tracing traces rays to a scene and conducts multiple bounces before returning a color to the camera.

Photon Mapping • The ray-tracing step uses the closest N photons to each ray intersection and estimates the outgoing radiance • Specular can be done using “usual” ray-tracing to reduce the number of photons needed • Numerous extensions to the idea to add more complex effects.

Compared to “traditional” ray tracing, where we only throw viewing rays into the scene, photon mapping uses a tow-pass rendering approach. In the first pass, photons are traced from light sources into the scene and get deposited after having interacted with objects in the scene.
What's the difference between path tracing, ray tracing …

With photon mapping you trace a ray from a light source and store the light energy for the area where the light hits an object. With path tracing you ray trace a ray from the camera and every time you hit an object you check if you can see a light source from that spot. If true you return all the gathered energy back to the camera (pixel).
