[vtkusers] vtkPlaneSource from a vtkPlaneWidget

[Luis Vieira]

Hello vtkusers,

 

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.
