R: [vtkusers] atan2 domain error and distance widget error

[Lazzarato Dr. Gianni]

Yes, I agree.       also for vtkDistanceWidget the bug I discovered ( an
error when reducing the RenderWindow containing the Widget) came from the
class vtkAxisActor2D who use a vtkTextMapper inside.

If I exclude the title of the widget
repr->GetAxis()->TitleVisibilityOff(); the bug disappear, so it seems
related to the text resizing when I reduce too much the renderWindow
containing the widget.
 
Someone can correct this?
 
For the AngleWidget I suspect the bug is here      void
vtkAngleRepresentation2D::BuildRepresentation()
 
Regards

Hi,

 

I have posted this error long time ago in the bugtracker, so far no answer.
The problem seems not the class vtkAngleWidget itself, its rather related to
a different behavior of one of it’s superclasses, I guess it is
vtkAbstractWidget. So in the end vtkAngleWidget needs to be changed to
accommodate this new behavior.

If you make any progress with it, let the forum know please.

 

Regards

 

Michael
