|
|
//
|
|
// In Maya Animation Curves (Anim Curve) are implemented as Dependency Graph
|
|
// (DG) Nodes. Each Node has multiple ordered and indexed keyframes.
|
|
//
|
|
// The Keyframe Iterator provides methods for iterating over, querying and
|
|
// editing the keyframes of a Anim Curve Node.

/**
|
|
|
|
Iterate over the keyframes of a particular Anim Curve Node, and query
|
|
and edit the keyframe to which the iterator points.
|
|
|
|
Determine the time and value of the keyframe, as well as the x,y values
|
|
and type of the tangent to the curve entering (in tangent) and leaving
|
|
(out tangent) the keyframe.
|
|
|
|
Set the time and value of the keyframe, and the type of the tangents.
