Game Development Reference
There are a number of ways a skeletal structure can be specified for animation.
The Humanoid Animation Working Group ( http://www.h-anim.org ) is an
international project with the goal of providing a standard profile for a humanoid
skeleton so it can be used consistently across a number of applications.
A partial view of the standard is illustrated in Figure 3.11 . This makes the process
of swapping characters in and out of games and virtual environments more
streamlined. Imagine being able to take your favorite character from Halo
and using it in The Sims . This of course would not work; however, if both
games used the same rules of the H-Anim specification it would.
