[vtkusers] Fw: Resetting the Camera

[Hua-Mei Chen]

Shady,

I had the same question before and did not get any helpful response. Finally I used GetPosition to store the initial camera position and SetPosition to restore its initial position. In addition, you need SetRoll( ) to set the initial roll angle. Hope this helps.

  That doesn't work. If you rotate the rendering object say left mouse click and then reset the camera It won't display the object in it's originial position. It eliminates operations done by zooming ofcourse but not rotating.

  Thanks
