Use
A model node with a modifiable transform to allow users to define their
own animations. While a model's asset can contain animations that target
a node's transform, this class allows users to change a node's transform
externally. In this way, animation can be driven by another source, not
just by the model's asset.
Model#getNode to get a node from a loaded model. Do not call the constructor directly.
使用示例:
const node = model.getNode("Hand");
node.matrix = Cesium.Matrix4.fromScale(new Cesium.Cartesian3(5.0, 1.0, 1.0), node.matrix);参考:

The index of the node in the glTF.
The node's 4x4 matrix transform from its local coordinates to
its parent's. Setting the matrix to undefined will restore the
node's original transform, and allow the node to be animated by
any animations in the model again.
For changes to take effect, this property must be assigned to; setting individual elements of the matrix will not work.
The value of the
name property of this node.
originalMatrix : Matrix4
Gets the node's original 4x4 matrix transform from its local
coordinates to its parent's, without any node transformations
or articulations applied.
Determines if this node and its children will be shown.
