Elsewhere in this book,
you’ve used the default perspective camera to examine and render
your modeling and animation work in progress. In some situations,
it is convenient to create and use additional cameras.
example, you might want to render the scene from two different camera views
to compare the results. Alternatively, you might want to use the
default camera for interactive modeling and animation and the second
camera strictly for rendering the scene. In the next steps, you
create an additional camera and manipulate its view of the scene.
To create a second camera for the scene
Create > Cameras > Camera.
This creates a perspective camera with an icon representing it at
the center of the grid.
the Channel Box, change the name
of the camera to myCamera.
Even though you’ve created
a new camera, you are still looking at the scene through the default
perspective camera named persp. You will view the scene
through myCamera after you position it in the next step. If you were
to view the scene through myCamera now, you would see a disorienting
view of the back wall and floor. The camera’s icon points in the direction
of the camera’s view.
The scene’s default persp
camera has no icon. An icon is displayed only for a camera you create.
- Use the Show Manipulator Tool (Modify
> Transformation Tools > Show Manipulator Tool)
to position myCamera roughly in this position:
With a camera selected,
the Show Manipulator Tool provides
the same two manipulators that you used to position the spotlight:
eye point and look-at point. The look-at point sets where the camera
aims. The eye point sets the position of the camera.
You can select the current
camera by selecting View > Select Camera.
- Select Panels > Perspective
> myCamera to view the scene from myCamera.
If your camera view is
not similar to the above illustration, select tableGroup in
the Outliner (Window
> Outliner) and select View > Frame Selection from
the panel menu. This centers the view of myCamera on the table.
The dolly, track, and
tumble movements work the same for myCamera as they do for the default
You can return to the
view of the persp camera by selecting Panels > Perspective
- While working with a camera, it’s useful
to know the exact region of the myCamera view that is displayed
in rendered images. To see the border of the render region, select View
> Camera Attribute Editor. In the Attribute Editor,
open the Display Options section and
turn on Display Resolution. A rectangular
border shows the region that will be rendered.
- In the Film Back section
of the Attribute Editor, set the Fit
Resolution Gate setting to Overscan.
By enabling the Overscan,
the view displays more of the region outside the area that will
By displaying a small
part of the scene that lies outside the rendered area, you can plan
future camera movement more easily, especially if the scene has
objects that move in and out of view.
