Hierarchical Radiosity Algorithm

The Hierarchical Radiosity Algorithm or HRA is a highly efficient sequential algorithm, whose entire point is simplifying level of detail in radiosity by using a hierarchy at the rendering phase determined by by distance from and importance to the viewpoint. Further objects, and peripheral objects gain a far lower level of detail and accuracy than those close at hand.

Below, we offer a selection of links from our resource databases which may match this term.

Hemisphere Lighting With Radiosity Maps
Rendering of lighting in outdoor scenes is a paramount concern. To truly be realistic, the light levels constantly vary, and the sun (or suns) are not usually even the primary lightsource! All that adds up to is a computational disaster, unless some way is found to render lightsoure data quickly, and easilly....

Reconstructing Cities in a Day
A computer algorithm developed at the University of Washington uses hundreds of thousands of tourist photos to automatically reconstruct an entire city in about a day.

WARP: Accelerating Wireless Technology Development
Prior to 2006, any attempt at investigating wireless technology, developing a new algorithm for propagation, or even trying for a whole new standard, all shared one thing in common: The phenomenal expense for the research team.

The Omni-focus
The omni-focus is a camera system with the ability to function much like the human eye - capturing objects in its field of vision regardless of the distance, in perfect focus. It even adapts an algorithm from VR, in order to do so.

Multiple Sensory Modalities Proven to Reinforce Each Other
Usually when we think of sensory input channels - sight, sound, touch, taste, smell, balance - we think of the traditional hierarchical order, under the brain. It seems that that hierarchy is not as cut and dried as we once thought, with interesting implications for virtual worlds.

Networked Virtual Environments: Design and Implementation

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.

The Human Brain has a Network Backbone
An unexpected discovery of a hierarchical networking scaffold inside the human brain itself, has interesting implications for future neuroprosthetics. Rather than having to interface with the grey matter right where computations are being done, we may in fact only have to interface with the white matter 'between departments' as it were, to achieve the same interface effect.

Virtual World Exchange Language
The virtual worlds of today are essentially hierarchical systems. A small number of servers which hold the data for the worlds, and an innumerable number of client connections, largely untrusted. This resource, half article/half rant, looks at the virtual worlds of tomorrow; at distributed systems, and world browsers.
