```
public class Node
extends GlTFChildOfRootProperty
```
A node in the node hierarchy. A node can have either the `camera`, `meshes`, or `skeletons`/`skin`/`meshes` properties defined. In the later case, all `primitives` in the referenced `meshes` contain `JOINT` and `WEIGHT` attributes and the referenced `material`/`technique` from each `primitive` has parameters with `JOINT` and `WEIGHT` semantics. A node can 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), only TRS properties may be present; `matrix` will not be present. Auto-generated for node.schema.json
