Parallax Mapping with Offset Limiting

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.

Parallax mapping with offset limiting is a variation of the technique which essentially caps the heightmap offset, preventing very large changes from occurring. With offset limiting, it is only through repetitive iterations that distortions become manifest.

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 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.

3D Visual Processing Centre Identified
Detecting 3D is a trait of stereoscopy. Its why humans tend to have two eyes, two different viewpoints create a degree of parallax, and allow us to perceive in 3D. However, motion parallax and movement in all three dimensions is harder to discern than simple 3D structure.

3-D Modeling Advance: A single photo can be reconstructed into a 3-D scene
Building on the premise of Parallax mapping, in which 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, Microsoft and Make3D have created a process allowing a single photo to become a 3D scene.

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.

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.

Using Blue Food Dye to Repair a Spinal Cord
A novel approach at limiting the damage done in spinal cord injuries, is to use a blue food dye to inhibit the body's repair mechanism. Its an approach that actually works.

Parallax Augmented Desktop
The PAD is another attempt to move beyond the flatland desktop paradigm. This one, thought up by researchers in Masatoshi Ishikawa's lab at the University of Tokyo, turns the desktop into a virtual 3D space directly.
