Extension Description

CurveMaker is a simple scripted module to generate a 3D curve from a fiducial list. Curves between fiducial points are interpolated by vtkSplineFilter. The curve is dynamically updated as the fiducial list is modified (moved/added/deleted). The module is useful to draw lines in 3D space, or visualize tracked catheters.

Use Cases

• Draw lines in 3D.
• Visualization of catheters.

Panels and their use

• Parameters
  • Source points: The list of fiducial points on the curve
  • Curve model: The model of the curve.
  • Radius: The radius of the curve model.
  • Interpolation: The method to interpolate the fiducial points.
    • None: The points are connected by a straight line.
    • Cardinal Spline: The default method.
    • Hermite Spline: The same interpolation method as the Documentation/Nightly/Modules/Endoscopy module. Useful for visualizing the trajectory of the virtual endoscope.
  • Ring Mode (Added June 1, 2015): Generate a closed-loop. (NOTE: Ring Mode does not support Hermit Spline. Ring Mode "On" is disabled, when Hermit Spline is selected.)
  • Enable: Start updating the curve model based on the curve. While this check box is on, the curve model is automatically updated whenever the parameters are modified.
• Measurements
  • Length: The length of the current curve is shown in millimeter.
