WebCams


In WebCam view and in the published content, you look at your World through a WebCam. By adjusting the WebCam, you control what appears on the screen.

By default, the World contains one WebCam. You can add any number of WebCams to look at the World from different points of view.

To add a WebCam to the World:
  1. Choose Visualization > Add WebCam.
  2. To see the World through the new WebCam, right-click a viewport, choose View, and select the new WebCam.
  3. In the World Explorer, select the webcam and adjust its parameters.
  4. To see the webcam icon, turn on Visible, then choose Viewpoint > Frame Selection or press F.

WebCam Parameters

Position

Sets the WebCam position.

Orientation

Sets the WebCam orientation, that is, the direction along which you look at your World.

Scale

Does not affect the WebCam.

Visible

Shows/hides the WebCam icon in construction views.

Background color

Sets the background color in the WebCam viewport. Enter an RGB or hexadecimal color value or click the color chip and use the Color Editor to set the background color.

Shade

Objects in the WebCam viewport appear filled or shaded. When Shade is turned off, objects appears as wireframe.

Orthogonal projection

Removes the Field of View (FOV) angle, thus creating a non-perspective view.

Interest
distance

Determines what the WebCam is looking at. Also determines the radius around which the WebCam orbits. Choosing Frame Selection moves the WebCam interest onto the selected object.

Near plane
distance

Indicates the distance between the WebCam and the beginning of the viewing frustum. Objects between the WebCam and the near plane are not visible. For more information on the near plane, far plane, and FOV, see About the viewing frustum.

Far plane
distance

Indicates the distance between the WebCam and the end of the viewing frustum. Objects beyond the far plane are not visible.

Near plane height

Determines the height of the plane, which in turn determines the vertical FOV angle.Changing the Near plane height is the same as changing the FOV. The Near plane width is adjusted automatically to maintain the aspect ration.

Vertical
FOV angle

Determines the vertical FOV angle, which in turn determines the Near plane height. Changing the vertical FOV angle has the effect of zooming in on the objects. The horizontal FOV is set automatically to maintain the aspect ratio of the viewer. The FOV cannot exceed 170 degrees.
