Active marker MoCap

Active marker MoCap, or Motion Capture, is an optical real-time body positioning and movement tracking method whereby a network of LEDs all over the body, positioned along bones, and between joints, are illuminated one after the other, at a rate too swift for the human eye to catch.

Rather than reflecting light back that is generated externally, as in passive marker MoCap, the LEDs each shine brightly, and their position in 3D space is recorded by software tied to multiple cameras watching from different angles. Distance is worked out, as each LED has the same intensity, so the brightness of each as a lightsource is used to determine distance.

As long as the results are processed at a rate of 60hz or over ? each LED cycled 60 times a second - real-time animation based on body positioning is possible.

World Review: Active Worlds welcome screen
Active Worlds is a crossbreed. Nominally used as a 3D chatspace, its also a hive of creative building, the codebase for several RPGs, and the source of inspiration for many new VR ventures.

AW itself is made up of a collection of worlds, sharing the same graphical base, yet it manages to maintain cohesion as a 'worldlet' of sorts itself.
