主题: [vtkusers] Rotation about a specific axis

 

Hi, 

 

I have subclassed vtkInteractorTrackballCamera class, and overloaded mouse
event functions to get what I want. By default, when you rotate the object,
you are free to rotate in any direction. 

 

What I want now is only rotating about one specific axis, say, x, y, z,
respectively. I don't have an idea to do this since I don't know which class
I need to use/subclass.

 

Do you know which class have such functionality? Any comment will be welcome
and I very appreciate your help. Thanks.

 

Chao
