vtkInteractorEventRecorder can be used to record VTK events in a single file and replay it by pass these events to vtkRenderWindowInteractor. Record The following code shows how to use it to save all interactive information into a file. We rotate Read more…
vtkAbstractWidget has its mechanism to handle interactive events. Here is a simple demo indicates the differences between the responses of widget and vtkInteractorStyleTrackballCamera. Example Code: int main() { vtkSmartPointer<vtkConeSource> cone = vtkSmartPointer<vtkConeSource>::New(); cone->Update(); vtkSmartPointer<vtkPolyDataMapper> coneMapper = vtkSmartPointer<vtkPolyDataMapper>::New(); coneMapper->SetInputData( cone->GetOutput() ); Read more…

It’s a simple job for us to make bounding box visible in traditional VTK render window. We can SetCurrentRenderer for renderWindowInteractor->GetInteractorStyle() and press P to show it. #include <iostream> #include <vtkSmartPointer.h> #include <vtkSphereSource.h> #include <vtkActor.h> #include <vtkConeSource.h> #include <vtkRenderer.h> #include Read more…
