vtkPropPicker

Section: Visualization Toolkit Rendering Classes

Usage

vtkPropPicker is used to pick an actor/prop given a selection point (in display coordinates) and a renderer. This class uses graphics hardware/rendering system to pick rapidly (as compared to using ray casting as does vtkCellPicker and vtkPointPicker). This class determines the actor/prop and pick position in world coordinates; point and cell ids are not determined.

To create an instance of class vtkPropPicker, simply invoke its constructor as follows

  obj = vtkPropPicker
