Real Time Radiography

Real Time Radiography or RTR, is a method of scanning physical objects such as living human or animal bodies, or artworks, in such a way as to be non destructive to these physical objects, but at the same time capture detailed data about their structure and composition in as close to real-time as possible. It is a direct-to-digital method of capture, so the data flows straight into a DICOM or PACS compatible datafile, which can then be loaded into the medical VR package of choice.

Typically RTR is optic tomography based, with an optic transmitter and a receiver continually rotating on opposite sides of the object being scanned. Data is collected and a 3D volumetric model constructed, based on the pattern of light that makes it through the object at a given frequency, and compiled from multiple shots at different angles right around the object.

Instantaneous Visual Virtual Face
One of the major issues with any virtual form, is facial expression. Traditionally, getting a virtual face to match your physical intent for expression in real-time, was a lost cause. Even for big budget film making, CG overlays had to be constructed frame by frame by hand. Enormously time consuming, ludicrously expensive and completely useless for real-time usage.

Protein Binding as a Virtual World
A new virtual environment, unveiled by researchers at the Southern Methodist University, is an interactive-real-time simulation of the human cell's 'sump pump', intended to allow researchers to interact with it in real-time, and determine how to bypass it for cancer cells.

A required reading book on real-time scene rendering that has been around for years, this book serves as a holistic, platform-independent guide for creating high frame rate renders that are as realistic as possible for the hardware available ? and teaches you where the bottlenecks are in the process so that you learn how to gauge new hardware from spec and understand how it will directly impact performance.

An Air Quality Sensor Web Made From iPhones
Researchers at the University of California demonstrate how to turn thousands of private iPhones into a single real-time sensor web, with the help of a plug-in sensor, and an app that provides enough real immediate benefit to the iPhone users thatthey'll run it much of the time. In this case, air quality sensors, complementing (and exceeding) the capabilities of the traditional air quality weather stations.

At the time of publication, it was the best book on the subject of networking real-time, multiple user, persistent environments. Although it is still on the market today, the problem is, it is almost hopelessly dated, still insisting on a hierarchical architecture, which was perfect at the time, but just cannot cope with large worlds today.
