Detailed Description

Extended PolyLineRepresentation adding angle display functionality.

This extends vtkPolyLineRepresentation to add angle visualization for 3-point angle measurement (Point1-Center-Point2), following ParaView's approach.

Key features:

  1. XYZ constraint support (inherited from vtkPolyLineRepresentation)
  2. Angle calculation and display (custom functionality)
  3. Arc visualization between the two rays (custom functionality)
Note
This is used with 3 handles configured for angle measurement: Handle 0: Point1 Handle 1: Center (vertex of the angle) Handle 2: Point2
