This picker is more conservative than vtkAreaPicker. It will reject some objects that pass the bounding box test of vtkAreaPicker. This will happen, for instance, when picking through a corner of the bounding box when the data set does not have any visible geometry in that corner.
To create an instance of class vtkRenderedAreaPicker, simply invoke its constructor as follows
obj = vtkRenderedAreaPicker
obj
is an instance of the vtkRenderedAreaPicker class.
string = obj.GetClassName ()
int = obj.IsA (string name)
vtkRenderedAreaPicker = obj.NewInstance ()
vtkRenderedAreaPicker = obj.SafeDownCast (vtkObject o)
int = obj.AreaPick (double x0, double y0, double x1, double y1, vtkRenderer renderer)
- Perform pick operation in volume behind the given screen coordinates.
Props intersecting the selection frustum will be accesible via GetProp3D.
GetPlanes returns a vtkImplicitFunciton suitable for vtkExtractGeometry.
