You could also get the matrix of<br>the camera (GetModelTransformMatrix) and then set the matrix of the<br>camera when you want to reset (SetModelTransformMatrix (vtkMatrix4x4<br>*matrix)).<br><br>(Actually I'm not sure the difference between the<br>vtkCamera::Get*Matrix functions - the documentation should be improved<br>here).<br><br>David<br><br> <!-- --><style></style></div></div>
