[vtk-developers] vtkPlaneSource by vtkPlaneWidget

[João Luis]

Hello vtkdevelopers,

I am trying to draw a vtkPlaneSource from a vtkPlaneWidget after some user
interactions. I had extracted Point1, Point2, Normal and Center from my
Widget as well. However, applying against a vtkPlaneSource the result does
not reflect the vtkPlaneWidget's definitions chosen by the user. It means,
basically size and orientation of the final plane. Many thanks for any help.

following my snapshot.

planeWidget = vtkSmartPointer<vtkPlaneWidget>::New();
planeWidget->SetInteractor(mouseClickCallback->renderWindowInteractor);
 //iren is vtkRenderWindowInteractor
planeWidget->SetInputConnection(mydataset);
planeWidget->SetPlaceFactor(1.0);
planeWidget->SetHandleSize(0.03);
planeWidget->SetResolution(10);
planeWidget->GetHandleProperty()->SetColor(0, 0.6, 0.1);
planeWidget->GetPlaneProperty()->SetColor(0, 0.3, 1);
planeWidget->GetPlaneProperty()->SetEdgeColor(0, 0.9, 1);
planeWidget->GetPlaneProperty()->SetEdgeVisibility(1);
planeWidget->PlaceWidget();
planeWidget->SetRepresentationToSurface();
planeWidget->GetPolyData(planeW);
planeWidget->AddObserver(vtkCommand::InteractionEvent, mouseClickCallback);
planeWidget->SetNormal(normalVector[0], normalVector[1], normalVector[2]);
// normal of my target plane
planeWidget->SetCenter(center[0], center[1], center[2]); // origin of my
target plane
planeWidget->UpdatePlacement();
planeWidget->EnabledOn();

Callback Interactions

_plane = vtkPlane::New();
vtkPolyData *polydata = vtkPolyData::New();
vtkSmartPointer<vtkExtractEdges> extractEdges =
vtkSmartPointer<vtkExtractEdges>::New();
planeWidget->GetPlane(_plane);
planeWidget->GetPolyData(polydata);
planeWidget->GetPoint1(Point1);
planeWidget->GetPoint2(Point2);
planeWidget->GetCenter(Center);
extractEdges->SetInputData(0, polydata);
extractEdges->Update();

vtkSmartPointer<vtkPlane> newPlane = vtkSmartPointer<vtkPlane>::New();
newPlane->SetNormal(planeWidget->GetNormal());
newPlane->SetOrigin(planeWidget->GetOrigin());

VtkPlaneSource

vtkSmartPointer<vtkPlaneSource> planeSource =
vtkSmartPointer<vtkPlaneSource>::New();
planeSource->SetPoint1(Point1[0], Point1[1], Point1[2]);//Point1
planeSource->SetPoint2(Point2[0], Point2[1], Point2[2]);//Point2
//planeSource->SetOrigin(newPlane->Origin[0], newPlane->Origin[1],
newPlane->Origin[2]);//
planeSource->SetCenter(Center[0], Center[1], Center[2]);
planeSource->SetNormal(newPlane->GetNormal()[0], newPlane->GetNormal()[1],
newPlane->GetNormal()[2]);
planeSource->Update();


Anybody here knows whats is wrong with my solution? Once, again many thanks
for any help.
