FlyThrough Producer Dialog, Camera Settings Section

Contains controls that are used to define the characteristics of the virtual camera's "lens" and "target."

Angle Sets the angle, in degrees, of the lens' "field of vision." As in a real camera, increasing the angle decreases the Focal Length.
Focal Length Sets the lens' "focal length," in millimeters, to widen the lens' field of vision. Decreasing the focal length increases the Angle, just as in a real camera.
Standard Lens Sets the angle of the lens' "field of vision" and the lens' "focal length" to simulate a standard camera lens.

Choosing a standard lens causes both the Angle and Focal Length to change. The lens names and their respective Angles and Focal Lengths are as follows:

Standard Lens Angle Focal Length (mm)
Fisheye 93.3° 20
ExtraWide 74.3° 28
Wide 62.4° 35
Normal 46.0° 50
Portrait 28.0° 85
Telephoto 12.1° 200
Telescopic 2.4° 1000
Front Clip Distance Sets the distance along the view z-axis, in working units, to the plane at which the camera begins to "see" elements in the design. Any part of an element closer to the camera than this plane is not included in the frame. If the plane "clips" an element, the frame will show a "slice" of that element.
Back Clip Distance Sets the distance along the view z-axis, in working units, to the plane beyond which the camera no longer "sees" elements in the design. Any element (or part of an element) further than this plane from the camera is clipped.
Target Position Affects the definition of the "target" at which the camera points:
  • Fixed — The camera always points at the same place while moving along the camera path. This is useful for aerials when you want to keep the camera focused on one point. Promis.e prompts for the location of the target point when Target Position is set to Fixed.
  • Floating — The camera always points in the direction tangent to the path. This is useful for simulating a walk-through, since the camera always points "straight ahead."
