// Description : This is a set of zero or more ParametricCurves, which
|
|
// may or may not be related. If they are related, the
|
|
// set should contain no more than one XYZ curve, no
|
|
// more than one HPR curve, and zero or more Timewarp
|
|
// curves, which can then be evaluated as a unit to
|
|
// return a single transformation matrix for a given
|
|
// unit of time.
