Field-of-View (on Field-of-View flyout)
Field-of-View (FO V) adjusts the amount of the
scene that is visible in a viewport a nd the amount
of perspective flare. The effect of changing FOV is
similar to changing the lens on a camera:
• AstheFOVgetslarger,youseemoreofyour
scene and the p erspective be comes distorted,
similar to using a wide-angle lens.
• AstheFOVgetssmaller,youseelessofyour
sceneandtheperspectiveflattens,similarto
using a telephoto lens.
Above: Narrow field of view
Below: Wide field of view
Although the effect of Field-of-View appears
similar to a zoom, the perspective is actually
changing, resulting in increased or decreased
distortion in the viewport.
In a Perspec tive viewport, Field-of-View defines
the width of your view as an angle with its apex
