This material should be used sparingly, as it may cause the light |
| 408 |

source calculation to blow up if it is applied to many small surfaces. |

The prism1 material is for general light redirection from prismatic |

It can only be used to modify a planar surface (i.e., a polygon or disk) |
| 431 |
|
and should not result in either light concentration or scattering. |
| 432 |
|
The new direction of the ray can be on either side of the material, |
| 433 |
|
and the definitions must have the correct bidirectional properties |
| 434 |

to work properly with secondary light sources. |

to work properly with virtual light sources. |

The arguments give the coefficient for the redirected light |
| 436 |
|
and its direction. |
