constructor

new Node(id: string, position: Vector, controlPoints: Vector[]): Node

- Defined in core/node.ts:86
A scene-graph Node

Parameters
- id: string
  
  A unique identifier for this node
- position: Vector
  
  Position where the node will be first initiated
- controlPoints: Vector[]
  
  A set of Vectors defining points of control for this Node, for e.g. for a Rectangle, the four corners are its control points, transformations such as position, rotation and scale are applied to these control points
Returns Node
