[vtkusers] TR: Translate with vtkBoxWidget

[Larcher Aurélie]

Hello !

I ask my question differently: How make you for translate an object with the
mouse’s left button pressed on the object (the object must follow the cursor
until the button is unpressed)

I use widget vtkBoxWidget but, as I explain it, it’s not really appropriated
for me (my 3D object is like a pen).

I also try to use vtkAffineWidget unsuccessfully (bad alignment due to the
representation 2D).

Please, can you indicate how you process?

Thanks for your help!

Objet : Translate with vtkBoxWidget

 

Hi all,

I use vtkBoxWidget for transform objects with the GetTransform method.

The object is like a pen : long and thin.

For the rotation, there is no problem. I can easily select one face for
change the orientation.

For the translation, I must to use the handle in the center of the
hexahedron. But my hexahedron is too thin. I find it’s difficult to select
only the center’s handle. When I change the size of handles, all handles
change size.

I don’t use the others handles because I’m not interested by scaling.  

How can I remove the others handles or how can I change property of a
defined handle.

I need to translate easily an object, just by selecting it.

Thanks for your help !
