Adjusting the View

The camera view is defined by the 3D position of the viewer and an aimpoint. The aimpoint is usually associated with an object in the scene.

ZOOMING and ROTATING involve moving the viewer position, while keeping the aimpoint in place. So the aimpoint is very important, since it is not only the center of the screen but also the center for these operations. PANNING, in contrast, will move both the aimpoint and the viewer position, so that a different part of the scene is centered and functions as an aimpoint..

WordsEye provides these ways to change the view:

To change the navigation and viewfinder mode, click on one of icons shown below.

  1. To interactively change the view: Hold down the left mouse button over the scene display area and drag the view up and down, or left and right. You can only adjust one axis at a time. You can also use the arrow keys ←↑→↓.

    You can use the ESC key to immediately exit any interactive camera move and restore the scene to its previous state. This is useful, since it avoids the scene having to be recomputed at the new position. Note that you can also use UNDO to undo the last completed camera move.
  2. Another way to change the view is to just select a view in the row of thumbnails in the Camera Viewfinder. These are organized by QUICK VIEWS, ROTATIONS, PANS, and ZOOMS and described above. Note that for PAN and ROTATION, re-clicking on the mode button will change the pan or rotation direction between horizontal and vertical.
