Pre-rendering

The concept of pre-rendering a scene occurs in passive VR only. It is a method by which intricate, detailed scenes are rendered slowly, sometimes over the course of many hours, and then stitched together, frame by frame, into a filmstrip effect.

This is the method used with CGI films, and is the cause of the disparity between them, and on the fly rendering in interactive virtual environments.

Rendering a VR for Viruses
University of Melbourne researchers have been utilising the full power of a dedicated IBM Blue Gene supercomputer to run a single massive virtual reality system - simulating the common cold virus inside and out. The purpose? To defeat it.

When Augmented Security Goes Pear Shaped
It has been revealed that a biometric pattern recognition system in use at Japan's airports has been bypassed for an unknown amount of time, effectively rendering it worthless, and raising questions about the reliance on technology as a 'watertight' security measure.

Knick Knack
Made in 1989, Knick Knack was a three minute short CG animation by Pixar Studios, featuring what was then the cutting edge of rendering capability, way beyond what real-time renders were capable of. To put it in perspective, this was just six years before Toy Story was released.
