<div dir="ltr"><div>Hi, </div><div> </div><div>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. </div>
<div> </div><div>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.</div><div> </div><div>Do you know which class have such functionality? Any comment will be welcome and I very appreciate your help. Thanks.</div>
