/**
|

|
|
* Represents a single character, as read and collected from several models
|
||
|
|
* and animation files. This contains a hierarchy of EggJointData nodes
|
||
|
|
* representing the skeleton, as well as a list of EggSliderData nodes
|
||
|
|
* representing the morph channels for the character.
|
||
|
|
*
|
||
|
|
* This is very similar to the Character class from Panda, in that it's
|
||
|
|
* capable of associating skeleton-morph animation channels with models and
|
||
|
|
* calculating the vertex position for each frame. To some degree, it
|
||
|
|
* duplicates the functionality of Character. However, it differs in one
|
||
|
|
* fundamental principle: it is designed to be a non-real-time operation,
|
||
|
|
* working directly on the Egg structures as they are, instead of first
|
||
|
|
* boiling the Egg data into native Panda Geom tables for real-time animation.
|
||
|
|
* Because of this, it is (a) double-precision instead of single precision,
|
||
|
|
* (b) capable of generating modified Egg files, and (c) about a hundred times
|
||
|
|
* slower than the Panda Character class.
|
||
|
|
*
|
||
|
|
* The data in this structure is normally filled in by the
|
||
|
|
* EggCharacterCollection class.
