Adjusting the Renderworks camera view

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

To adjust the camera view:

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 Shaded 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.

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° range, as if it were on a tripod

Camera Move Left/Right

Rotates the camera about the look-to point, within a +/- 20° 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

Crop Frame Aspect Ratio

Sets the aspect of the perspective crop window; use in conjunction with the Crop Frame Size to obtain the desired window size

Crop Frame Size

Sets the scale of the perspective crop window; use in conjunction with the Crop Frame Aspect Ratio to obtain the desired window size

Render Mode

Selects a render mode for the 3D camera view

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.

Fill/pen color attribute

Parameter

Fill foreground

Sets the field of view angle color when the camera height is higher than the look-to height

Fill background

Sets the text color for the camera name

Pen foreground

Sets the color of the view line connecting the camera to the look-to point, as well as the color of the 3D camera representation

Pen background

Sets the color of the angle of view lines

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.
