To simulate a particular camera's aperture, divide the focal length of |
107 |
+ |
the lens by the f-number, then convert to the corresponding |
108 |
+ |
world coordinate units. |
109 |
+ |
For example, if you wish to simulate a 50mm lens at f/2.0 in |
110 |
+ |
a scene modeled in meters, then you divide 50mm by 2.0 to get 25mm, |
111 |
+ |
which corresponds to an effective aperture of 0.025 meters. |
