declaration to work. You have declared a local instance of<br>
vtkSmartPointer<vtkTransform> and so the full definition is required. Forward<br>
declarations can only be used when you are using pointers or references.<br>
<br>
The smart pointer becomes fairly useless when you need to use a pointer to it<br>
though, as you then have to destroy it yourself and so you may as well use a<br>
pointer to the object.<br>
