To see the camera and frustum:
- From the View box, select Side.
- In the image window controls, click to zoom out from the scene.
- Select Pan in the Tools box and pan around the scene until you see the camera eye icon. Alternatively, use Orbit mode to pan around the scene in circular motion.
- Go to the Camera menu and drag the Roll field until you see the four sides of the frustum.
- To modify the frustum, do one of the following:
- Change the position of the near clipping planes to alter the depth of the frustum. See Moving the Clipping Planes.
- Change the position of either the camera eye or the camera's point of interest to alter the orientation of the frustum. See Moving the Camera Eye and Point of Interest.
- If the Physical Camera button is disabled, enter a value in the FOV (field of view) field to adjust the width of the camera frustum.
- If the Physical Cam button is enabled, enter a value in the Focal Length field to narrow or widen the frustum. You can also alter the depth of the frustum using only the near clipping plane.
