33.19.28 Camera Parameters Dialog Box

The Camera Parameters dialog box allows you to modify the "camera'' through which you are viewing the graphics display. See Section  29.5.2 for details about the items below.

Controls

Camera   contains a drop-down list of the parameters that define the camera ( Position, Target, Up Vector, and Field) and X, Y, and Z fields in which you can define the coordinates or field distances for the parameter selected in the drop-down list. Figure  29.5.5 illustrates the definition of the camera by these parameters.

Projection   contains a drop-down list that allows you to select a Perspective or Orthographic view.

(Dial and Sliders)   allow you to rotate and scale the graphics display. The slider on the scale to the left of the dial rotates the display about the horizontal axis at the center of the screen, the slider on the scale below the dial rotates the display about the vertical axis at the center of the screen, and the dial controls rotation about the axis at the center of and perpendicular to the screen. The slider on the scale to the right of the dial zooms in or out in the display. See Sections  29.5.1 and 29.5.1 for details.

When you are using the sliders and dial to manipulate the view, you may want to turn off Wireframe Animation in the Display Options dialog box, so that you can watch the display move interactively while you are moving the slider or the dial indicator.
