| 106 | + | 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. |
