|
Set hemisphere sampling to "uniform," meaning a single bin |
| 83 |
|
of (cosine-distributed) samples. |

In the case of distant "source" primatives, this is the only |
| 84 |
> |
In the case of distant "source" primitives, this is the only |
| 85 |
|
sampling method that supports arbitrary receiver sizes. |
| 86 |
|
The other methods below require a full hemispherical source. |

|
.TP |
| 142 |
|
Large displacements may give rise to errors due to a convex receiver's |
| 143 |
|
larger profile at low angles of incidence. |

.PP |

Rays always eminate from the back side of the sender surface and arrive at the |

> |
Rays always emanate from the back side of the sender surface and arrive at the |
| 146 |
|
front side of receiver surfaces. |
| 147 |
|
In this way, a receiver surface may be reused as a sender in a subsequent |
