Variables in |
41 |
|
.I rfile |
131 |
|
The |
132 |
|
.I \-o |
133 |
|
option specifies an output device for |
134 |
< |
.I rview |
134 |
> |
.I rvu |
135 |
|
(usually "x11") |
136 |
|
and runs this interactive program instead, using the first view in |
137 |
|
.I rfile |
200 |
|
It is important to set this variable properly as it is used to |
201 |
|
determine the ambient value. |
202 |
|
An appropriate setting may be discovered by running |
203 |
< |
.I rview |
203 |
> |
.I rvu |
204 |
|
and noting the exposure given by the "exposure =" command. |
205 |
|
As in |
206 |
< |
.I rview |
206 |
> |
.I rvu |
207 |
|
and |
208 |
|
.I pfilt, |
209 |
|
the exposure setting may be given either as a multiplier or as a |
405 |
|
values will be stored by |
406 |
|
.I rpict |
407 |
|
or |
408 |
< |
.I rview. |
408 |
> |
.I rvu. |
409 |
|
Although it is not required, an ambient file should be given whenever |
410 |
|
an interreflection calculation is expected. |
411 |
|
This will optimize successive runs and minimize artifacts. |
445 |
|
This file can later be accessed by |
446 |
|
.I rpict |
447 |
|
or |
448 |
< |
.I rview |
448 |
> |
.I rvu |
449 |
|
in subsequent manual runs using the at-sign ('@') file insert option. |
450 |
|
(Using an "OPTFILE" also reduces the length of the rendering |
451 |
|
command, which improves appearance and may even be necessary on some |
486 |
|
This variable may be used to specify additional options to |
487 |
|
.I rpict |
488 |
|
or |
489 |
< |
.I rview. |
489 |
> |
.I rvu. |
490 |
|
These options will appear after the options set automatically by |
491 |
|
.I rad, |
492 |
|
and thus will override the default values. |
574 |
|
Now we can invoke |
575 |
|
.I rad |
576 |
|
to take a look at our scene interactively with |
577 |
< |
.I rview: |
577 |
> |
.I rvu: |
578 |
|
.IP "" .2i |
579 |
|
rad -o x11 sample.rif |
580 |
|
.PP |
583 |
|
.I oconv |
584 |
|
first to create the octree (assuming it doesn't |
585 |
|
already exist), then |
586 |
< |
.I rview |
586 |
> |
.I rvu |
587 |
|
with a long list of options. |
588 |
|
Let's say that from within |
589 |
< |
.I rview, |
589 |
> |
.I rvu, |
590 |
|
we wrote out the view files "view1.vp" and "view2.vp". |
591 |
|
We could add these to "sample.rif" like so: |
592 |
|
.IP "" .2i |
597 |
|
.fi |
598 |
|
.PP |
599 |
|
To start |
600 |
< |
.I rview |
600 |
> |
.I rvu |
601 |
|
again using vw2 instead of the default, we use: |
602 |
|
.IP "" .2i |
603 |
|
rad -o x11 -v vw2 sample.rif |
653 |
