of opening them in other programs. I went through and found similar |

(potential) bugs in the rview device subprocess code and util/netproc.c. |

Corrected the normalization of the Gaussian reflectance model. This will |

cause an increase in specularity for low-lying light sources. |

Thanks to Don Walters of Boeing and Arne Duer of the Univ. of Innsbruck |
| 1324 |

for pointing out this error. The square root used for the two cosines |

in the denominator of the normalization factor should not be present. |

This was a serious mistake I made in the original model, which went |
| 1327 |
+ |
undiscovered (at least to my knowledge) for over a decade. I think |

Bruce Walter of Cornell may have known about it, but I never heard |
| 1329 |

the details of his discovery. |
