```
public class Node
extends GlTFChildOfRootProperty
```
A node in the node hierarchy. When the node contains `skin`, all `mesh.primitives` **MUST** contain `JOINTS_0` and `WEIGHTS_0` attributes. A node **MAY** have either a `matrix` or any combination of `translation`/`rotation`/`scale` (TRS) properties. TRS properties are converted to matrices and postmultiplied in the `T * R * S` order to compose the transformation matrix; first the scale is applied to the vertices, then the rotation, and then the translation. If none are provided, the transform is the identity. When a node is targeted for animation (referenced by an animation.channel.target), `matrix` **MUST NOT** be present.
