|
There are two basic ways to compute the exposure value. |
| 489 |
|
The first is by trial and error, where the value is adjusted up and |
| 490 |
< |
down within rview using the "e = value" command. |
| 490 |
> |
down within rvu using the "e = value" command. |
| 491 |
|
Though it sounds flaky, this is the most reliable way to set the |
| 492 |
|
exposure (and ambient level) in general lighting situations. |

The first view in the list is the default given to rvu during |
| 549 |
|
interactive rendering, and is the first view rendered in a batch run. |

To change the default view, select the newly desired view and press |

the "Set Default" button. |

define a view. |

|
The simplest view specification is of the form "-vf viewfile", where |
| 617 |
< |
"viewfile" is a file created with the rview "view" command, or a |
| 617 |
> |
"viewfile" is a file created with the rvu "view" command, or a |
| 618 |
|
Radiance picture. |
| 619 |
|
This method of naming views, although convenient, is not the best |
| 620 |
|
since it is difficult to know exactly where such a view is by |
| 702 |
|
The "Set Default" button may be used to make the selected view the |
| 703 |
|
default view for rendering. |
| 704 |
|
This simply moves the view to the top of the list in the rad input file. |
| 705 |

The default view will be the one normally rendered by rview when rad |

The default view will be the one normally rendered by rvu when rad |

The "Optfile" setting assigns a file to hold rendering options, |
| 918 |
|
which may be a convenience when these options are reused for |
| 919 |
< |
rtrace(1) or rpiece(1), or manual invocations of rview or rpict. |

rtrace(1) or rpiece(1), or manual invocations of rvu or rpict. |

Using an options file also reduces the size of the command line, |
| 921 |
|
making it a little easier on the eye. |

the rvu(1) and rpict(1) rendering programs. |

|
Most of the important parameters are computed by rad, so this |
| 982 |
|
window is usually used to override specific parameters or to give |
| 983 |
|
additional information, such as which materials to exclude from the |
| 1026 |
|
run, usually via rad(1). |

The Action screen contains two menus for selecting views. |

The top menu, next to the "rvu" button, sets the view to start |

with in rvu, and is selected from the current view list. |

The second view menu, next to the "Start" button for batch |
| 1134 |
|
rendering, selects the view or views to render in batch mode. |
| 1135 |
|
If the special entry "ALL" is selected, then every view in the |
| 1136 |
|
current list will be rendered if it hasn't been already. |

| 1140 |
|
The view menu next to the "Start" button will be disabled if there |
| 1141 |
|
is a batch job in progress, and thus the view cannot be changed. |
