// Class : EggCharacterData
|
|
// Description : 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.
