[vtkusers] atan2 domain error

[Lazzarato Dr. Gianni]

Hi vtkusers,

                 i'm triing to compile these examples available in the vtk
source tree : TestDistanceWidget and it works perfectly under Borland 2006
and vtk 5.01;

                 I'm triing also the example TestAngleWidget but it return
an error:  ATAN2 domain error in vtkAngleRepresentation2D- line 166

 

Some ideas? Where is wrong?

I suppose the trouble is related to these 3 points not yet initialized, am I
in right?

 

Thanks for any suggestions.

Gianni
