Adjusting the Camera View

The camera view settings can be fine tuned in real-time, and the display attributes specified.

To adjust the camera view:

1. Click Fine Tune Camera View from the Object Info palette of a selected camera object.

The Perspective View Controls dialog box opens. Either use the sliders or enter values to adjust the camera settings; changes are reflected automatically in the drawing. To interactively view changes as you move the sliders, render in wireframe or OpenGL render mode.

For Camera Height, Look To Height, and Camera Distance, the slider range is proportional to the displayed value. To expand the slider range, enter a larger value.

Click to show/hide the parameters.

Parameter	Description
Camera Height	Moves the camera vertically
Look To Height	Sets the height of the look-to point, which effectively tilts the camera vertically
Camera Pan	Pans the camera, rotating it about its axis within a +/- 20 degree range, as if it were on a tripod
Camera Move Left/Right	Rotates the camera about the look-to point, within a +/- 20 degree range
Camera Distance	Moves the camera towards or away from the look-to point
Focal Length (zoom)	Acts like a zoom lens; sets the lens focal length, from 10 to 200 mm and changes the field of view angle
Perspective	Increases or decreases the perspective effect, making the perspective lines vanish more or less steeply about the look-to point; works most effectively when the look-to point is at the center of the scene or object being viewed
Clip Frame Aspect Ratio	Sets the aspect of the perspective crop window; use in conjunction with the Clip Frame Size to obtain the desired window size
Clip Frame Size	Sets the scale of the perspective crop window; use in conjunction with the Clip Frame Aspect Ratio to obtain the desired window size
Render Mode	Selects a render mode for the 3D camera view

2. A camera object can be copied to insert additional camera views. In addition, the 2D camera display attributes can be set by fill and pen foreground and background colors in the Attributes palette. Control points adjust the field of view angle, the look-to point, and the camera name location.

The divergence between the apparent field of view angle and the lens field of view angle increases as the difference between the camera and look-to heights increases. When the camera and look-to heights are equal, the lens field of view angle line (dashed gray line by default) is not visible.
