ActiveZoom
is a simple MEL script for Maya that creates a
dialog with controls that change overscan and
filmOffset of a perpective camera. It allows to
zoom and pan a perpective view without moving
the camera. Useful for camera tracking.

To
use activeZoom, you have to create a Hotkey (I suggest
Alt+z). When executed, it automatically gets the panel
under the mouse pointer. It the panel is a perpective
camera, a dialog box appears showing controls for zooming
and Panning. Otherwise, a warning message is displayed
in the Command Feedback. This is the reason why activeZoom
cannot be added to the Shelf.
ActiveZoom
controls:
- Zoom
allows to zoom the camera whitout moving it or changing
its focal lenght;
- PanX
and PanY allow to center the zoom area;
- Reset
sets the camera to a default zoom and pan value.
In
order to save a file for rendering, be sure to press
the Reset button of ActiveZoom. If you don't do that
the rendering result may by horizontally or vertically
shifted.
ActiveZoom
doesn't modify the camera animation in any way, so it
can be very helpful if you want to temporarily zoom
a moving camera. A tipical example is a camera tracking
task, on which is necessary to look in detail the contact
areas between the 3d geometry and the live background,
without having the possibility of moving the camera.
