/** \class plAGAnim |
|
This class holds reusable animation data. A single plAGAnim can be instanced |
|
any number of times simultaneously. |
|
In order to use a plAGAnim, you need a plAGMasterMod, which is a special type of |
|
modifier which can be attached to multiple scene objects. A master mod is typically |
|
applied to the root of a scene branch, but there is no requirement that all the scene |
|
objects animated be children. |
|
Each plAGAnim has a number of channels, each of which can animate a single parameter |
|
of a single object. Channels are parametric, i.e. they can carry any data type. |
|
A plAGAnim carries a name for the animation, and each channel is named as well. |
|
Instancing a plAGAnim is done via a plAGAnimInstance. |
