<p>Hi,</p>
<p>I'm new to vtk<a></a> and I need to modify existing vtk<a></a> code to allow "zoom to mouse" in the 3D<a></a> window using the mouse wheel. This is similar to zoom implemented in google<a></a> maps but in 3D<a></a>. From what I've read looks like I need
to override the OnMouseWheelForward<a></a>() and OnMouseWheelBackward<a></a>() methods of my particular derivation of vtkInteractorStyle<a></a> but I'm wondering if vtk<a></a> already offers something to accomplish this type of zooming.</p>
<p>Any information<a></a> on this will be really helpful.</p>
<p>Thanks,</p>
<p>Alfredo</p>
