Offset Mapping

Offset mapping is an alternate name for parallax mapping.

Parallax mapping is a system by which textures displayed on flat surfaces are give the illusion of 3D depth, extruding out into the viewpoint, and making the object they cover seem more real, shadows changing as the viewpoint moves round it.

3D displacement of surfaces is faked by means of displacing textures both by creating a height map of their protuberance from 3D space and then calculating the angle of that protuberance relative to the angle the observer is looking from.

Flexible Power for Prosthetics
Providing power for prosthetic devices has always been somewhat of a tricky endeavour, frought with compromises. Battery packs are heavy, cumbersome and heat up quite significantly. They have to be carefully placed, to avoid upsetting balance, and the weight offset by stripping out material elsewhere.

A Closer Look At Parallax Occlusion Mapping
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.

Mapping cyberspace

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.

Augmented Reality Mapping: Tokyo's Nameless Streets
Tokyo. Quite possibly, the birth place of the true sensor web. Birthing, right now.

Large Image Display: Animatrix: Beyond: The Matrix VR Map
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.

Parallax Textures, Made with Camera Flash
A new method of creating parallax mapping has been demonstrated, which can automatically create parallax texturemaps from ordinary photographs.

A Golden Age of Brain Exploration
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.
