geometry
The geometry attached to the node.
Declaration
var geometry: SCNGeometry? { get set }Discussion
A node can have only one geometry attached to it. To combine geometries so they can be controlled or animated together, create a node with no geometry and add other nodes to it.
Animating the node’s geometric properties can move, rotate, stretch and scale its geometry. For more advanced animations of a node’s geometry, use its morpher and skinner objects.
