Setting a Camera View in RenderWorks

RenderWorks contains a method of setting a camera view with the RenderWorks Camera tool. Specific attributes, such as camera focal length, field of view, height, and aspect ratio can be set.

 

To insert a RenderWorks camera:

1.	Select the RenderWorks Camera tool from the Visualization tool set (RenderWorks required).

2.	Click in the design layer to specify the camera location. Click again to indicate the camera look-to point.

If this is the first time a camera object has been inserted in this session, the RenderWorks Camera Object Properties dialog box opens. Click OK.

3.	Click Display Camera View in the Object Info palette, or simply double-click on the camera, to switch to the 3D camera view. To return to Top/Plan view, click Top/Plan View in the Object Info palette.

4.	The camera properties can be edited in the Object Info palette.

 

Parameter	Description
Camera Height	Sets the camera height; at placement, the camera is set to a default height of 1500 mm or 5’0”. If a Z value is also specified for the camera object, the total camera height is the sum of the Z height and the Camera Height.
Look To Height	Sets the height of the camera look-to point; at placement, the look-to height is set to a default height of 1500 mm or 5’0”. If a Z value is also specified for the camera object, the total look-to height is the sum of the Z height and the Look To Height.
Top/Plan View	Switches to a Top/Plan view of the 2D camera
Display Camera View	Switches to display the 3D camera view (double-clicking on the camera in a 2D view also switches to camera view)
Fine Tune Camera View	Opens the Perspective View Controls dialog box, for making fine adjustments to the camera view controls (see Adjusting the Camera View)
Projection	Select Perspective or Orthogonal projection for the camera view; Perspective creates an adjustable clipping frame for the camera view, while Orthogonal is useful for an elevation view (for example, a skewed elevation view of a building which is not in a standard view). Available parameters depend on the selected projection.
Render Mode	Selects a render mode for the 3D camera view
Aspect Ratio	Sets the aspect ratio of the perspective clipping window; the clipping window can also be set to the page size or to a custom aspect ratio
Custom Aspect	When a custom Aspect Ratio is selected, enter the custom ratio
For Film Size of	Specifies the camera film size, and determines the focal length of the camera (has no effect on the camera view)
Focal Length is	Displays the camera focal length, based on film size
Field of View	Specifies the view angle; set to a default angle of 65 degrees. Use the control point to set the view angle on the 2D camera with the mouse.
For DPI of	Calculates the pixel size when exporting the camera view (has no effect on the camera view)
Pixel Size is	Displays the pixel size based on the DPI setting
Clip Frame Scale %	Scales the size of the clipping window frame
Left/Right Tilt Angle	Tilts the camera to the left or right, for more accurate perspective matching
Camera Name	Specifies a name for the camera, which can be displayed or hidden in 2D view; move the camera name text control point to adjust the position of the name
Camera Display	Select a camera display mode; the camera name only displays in 2D None: Hides the camera in 2D and 3D views, and hides the camera name 2D: Displays the camera in 2D view, but hides the camera name, and hides the camera in a 3D view 3D: Displays the camera’s perspective clipping window bounding box in 2D view, displays the camera in 3D view, and hides the camera name 2D + 3D: Shows the camera in 2D and 3D views, but hides the camera name 2D + Name: Shows the camera and camera name in 2D view, but hides the camera in 3D views 3D + Name: Shows the camera in 3D view, shows the camera name in 2D view, but hides the camera in 2D view (displays a locus instead) 2D + 3D + Name: Shows the camera and camera name in 2D view, and shows the camera in 3D views The 3D camera view displays the bounding box of the camera view, the view line, and the look-to end point. Displaying a camera in a 3D view allows it to be easily selected during design development, and it can be hidden later for final presentation
Auto Update 3D View	When selected, automatically updates the 3D camera view with every parameter change; for complex models, deselect when making several parameter changes, and then either re-select Auto Update 3D View or click Display Camera View to update the camera view with any parameter changes
