[vtkusers] Setting interactor views (coronal, sagital, axial)

[Sergio Vera]

Hi David,
It's not working :(

here is the snippet of my code:


void
SliceRenderView::SetView(
ViewType a_view)
{
d_view = a_view;
 switch (d_view) {
case eAxial: {
d_interactorStyle->SetZViewRightVector(1,0,0);
d_interactorStyle->SetZViewUpVector(0,1,0);
}
break;
case eSagittal: {
d_interactorStyle->SetXViewRightVector(0,1,0);
d_interactorStyle->SetXViewUpVector(0,0,1);
}
break;
case eCoronal: {
d_interactorStyle->SetYViewRightVector(1,0,0);
d_interactorStyle->SetYViewUpVector(0,0,1);
}
break;
case eOblique:
 default:
std::cout << "Unimplemented" << std::endl;
}
this->setCornerAnnotationText(d_ViewText[d_view]);
this->renderer()->ResetCamera();
d_interactorStyle->SetImageOrientation(d_interactorStyle->GetZViewRightVector(),
d_interactorStyle->GetZViewUpVector());
/*
this->renderWindow()->Render();
this->renderWindow()->GetInteractor()->Render();
this->repaint();
*/
}

It gets called when the image has been loaded

void
SliceRenderView::setImageData(
VolumeData* a_data)
{
std::cout << __FUNCTION__ << std::endl;

d_image = a_data->GetImage();
d_imgResliceMapper->SetInput(d_image);
d_imgSlice->SetMapper(d_imgResliceMapper);
d_imgSlice->SetProperty(d_imgProp);
this->SetView(d_view);
this->renderWindow()->Render();
this->renderer()->ResetCameraClippingRange();
}

Any hints on what can be wrong?
