Hierarchical Radiosity

The concept of hierarchical radiosity is key to the efficient display of diffuse illumination in a 3D virtual environment. Using the hierarchical radiosity algorithm, the level of detail in radiosity ? how much care and accuracy is to be taken ? is determined in the hierarchy by distance from and importance to the viewpoint.

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....

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.
