[vtkusers] How to initialize vtkAngleWidget with three points specified?

[Gelas, Arnaud Joel Florent]

Hi,

Note: By sending this email on the list, you may get better answers which could benefit to everyone :-)! 

You're right you can specified the location of these 3 points directly in vtkAngleWidget, you need to do it through vtkAngleRepresentation.

You can have a look at the following example:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Widgets/vtkAngleWidget_2D

and the doxygen documentation of vtkAngleRepresentation:
http://www.vtk.org/doc/nightly/html/classvtkAngleRepresentation.html

Then you can specify these 3 locations.

I also invite you to modify the wiki example to show such an usage!

Best,
Arnaud

Hi Arnaud Gelas,

I have been trying to initialize vtkAngleWidget with three points specified, but vtkAngleWidget has not SetPoint1WorldPosition()、SetPoint2WorldPosition() and SetCenterWorldPosition() function
So I don't know how to initialize it, Can you tell me what I am doing that, please?
