To simulate a particular camera's aperture, divide the focal length of |

the lens by the f-number, then convert to the corresponding |

world coordinate units. |

For example, if you wish to simulate a 50mm lens at f/2.0 in |
381 |
+ |
a scene modeled in meters, then you divide 50mm by 2.0 to get 25mm, |
382 |

which corresponds to an effective aperture of 0.025 meters. |

The default aperture is 0, meaning no depth-of-field blurring. |
