Photon mapping is a version of raytraced lighting, that is neither raytraced nor raycast. Instead, it combines the two methods. Rays from the light source and rays from the camera are traced independently of one another, until they meet in the middle ? or a set length is exceeded, not meeting another beam. Those that meet and are travelling in the same direction are kept, all others are discarded. The process continues until all rays have met a partner. Considerable excess calculation is often required.

As the demands for precise imaging in fields such as medicine, astronomy, and real-time machine vision in hostile environments continue to increase, so the demands placed on imaging equipment become ever more stringent. An imaging method based on Single Photon Avalanche Photodiodes (SPAD) offers the potential to ease this bottleneck greatly.
An in-depth Gamedev article, containing step by step coding advice for implementing parallax occlusion mapping to textures, such that the simulated heights can even self-occlude.
This book is an attempt to cross-reference the techniques of mapping and charting the physical world, with attempts to chart cyberspace. All of cyberspace, from individual virtual environments, through to the world wide web, as a single cohesive whole, a second world of many worlds, for others to explore, possessing the maps to do so.

This image is all about mapping, and more specifically how to preserve all necessary high level information in a virtual environment, in a cut down form, to allow easy oversight.
A new method of creating parallax mapping has been demonstrated, which can automatically create parallax texturemaps from ordinary photographs.
The Allen Brain Atlas, a project like never before: Literally a mapping of the human brain, an attempt to make connections between anatomical, genetic, and behavioral observations.
Eventually maps became digital, and all manner of computerised versions sprung up. Yet, for all the centralisation, and innovation, one thing never changed: For all their promise, computer based maps look, and function exactly the same as their printed brethren.
"Today a brain scan reveals our thoughts, moods, and memories as clearly as an X-ray reveals our bones. We can actually observe a person's brain registering a joke or experiencing a painful memory."
