A bookmark has the following options:
- Perspective — If selected, the camera will give a perspectively correct image. If not selected, the camera will operate in orthogonal mode where parallel edges will also appear as parallel lines in the 3D viewport. You can switch between perspective and orthogonal mode by pressing P or selecting Orthogonal View from the Focal Length menu.
- Angle of view — The width of the field of view. For your convenience, some predefined angles of view corresponding to specific focal lengths are accessible from the Focal Length menu.
- Rotate/Translate — These values position and orient the camera. You can enter a world coordinate position for the camera as well as a specific rotation of the camera.
- Distance to Point of Interest — This value corresponds to the distance between the camera and the POI. The POI is also the center of rotation and thus the distance to the POI defines the radius of the camera rotation.
