The central program is <i>rpict</i>, which produces a picture from a scene |
| 85 |
|
description. |
| 86 |
< |
<i>Rview</i> is a variation of rpict that computes and displays images |
| 86 |

<i>Rvu</i> is a variation of rpict that computes and displays images |
| 87 |
|
interactively, and rtrace computes single ray values. |
| 88 |
|
Other programs (not shown) connect many of these elements together, |
| 89 |
|
such as the executive programs |
| 822 |
|
Also, rather than roughness, specular power is used, which has no |
| 823 |
|
physical meaning other than larger numbers are equivalent to a smoother |
| 824 |
|
surface. |
| 825 |
+ |
Unlike other material types, total reflectance is the sum of |
| 826 |
+ |
diffuse and specular colors, and should be adjusted accordingly. |

When the user specifies a new perspective, rvu quickly displays a rough image on the terminal, |

|
then progressively increases the resolution as the user looks on. |
