created novel production technologies that allow shared
3-D virtual worlds to be recorded, replayed and edited.
These recordings are not video. They are full 3-D recordings.
Every action movement, object manipulation and
talk of every avatar in a virtual world is logged
and time-stamped in enough detail to recreate faithfully
the virtual world as it happened at some later time.
Using a technique
called temporal links within the MASSIVE-3 system, the
replay of a virtual world can be embedded within a live
virtual world. Live participants see the replayed action
unfold around them and can move through it, viewing
it from any angle. Temporal links also allow these replays
to be manipulated in a variety of ways. They can be
scaled up and down, and run forwards and backwards,
at any speed and yet still animate smoothly. Their appearance
can be also manipulated so they may appear to be ghostlike.
The live world containing the recording can then be
recorded for later use.
links, Avatar Farm included
the first ever examples of 3-D flashbacks within a virtual
world, and 3-D recordings of the whole of Avatar Farm
have been used in complex post-production.
