[vtk-developers] VtkLineWidget2 InteractionEvent distance

[carlinhos]

Hi all!

Finally, i solved it using a vtkCellPicker explicit to get the world point
where the mouse is, in case I use the picker returned by the interactor the
coordinates seem wrong many times. This is the new code:

*vtkSmartPointer<vtkCellPicker>  picker = 
vtkSmartPointer<vtkCellPicker>::New();
int* clickPos = m_rwi->GetEventPosition();

if ( state == vtkLineRepresentation::OnP1 ) {
					if (picker->Pick(clickPos[0], clickPos[1], clickPos[2], m_renderer)) {
						double picked[3];
						picker->GetPickPosition(picked);
						lineRepresentation->SetPoint1WorldPosition(picked);
						PrintPointsPosition(oldLineRepresentation);
					}
}else 	if ( state == vtkLineRepresentation::OnP2 ) {
					

					if (picker->Pick(clickPos[0], clickPos[1], clickPos[2], m_renderer)) {
						double picked[3];
						picker->GetPickPosition(picked);
						lineRepresentation->SetPoint2WorldPosition(picked);
						PrintPointsPosition(oldLineRepresentation);
					}
}*

Thanks to everyone!!! :)
