.TH RPICT 1 2/26/99 RADIANCE |
| 3 |
|
.SH NAME |
| 4 |
|
rpict - generate a RADIANCE picture |
| 89 |
|
.BI -vd " xd yd zd" |
| 90 |
|
Set the view direction vector to |
| 91 |
|
.I "xd yd zd". |
| 92 |
+ |
The length of this vector indicates the focal distance as needed by the |
| 93 |
+ |
.I \-pd |
| 94 |
+ |
option, described below. |
| 95 |
|
.TP |
| 96 |
|
.BI -vu " xd yd zd" |
| 97 |
|
Set the view up vector (vertical direction) to |
| 166 |
|
.BI -vf \ file |
| 167 |
|
Get view parameters from |
| 168 |
|
.I file, |
| 169 |
< |
which may be a picture or a file created by rview (with the "view" command). |
| 169 |
> |
which may be a picture or a file created by rvu (with the "view" command). |
| 170 |
|
.TP |
| 171 |
|
.BI -x \ res |
| 172 |
|
Set the maximum x resolution to |
| 229 |
|
.I \-pm |
| 230 |
|
option, to avoid the ghosting effect of too few time samples. |
| 231 |
|
.TP |
| 232 |
+ |
.BI -pd \ dia |
| 233 |
+ |
Set the pixel depth-of-field aperture to a diameter of |
| 234 |
+ |
.I dia |
| 235 |
+ |
(in world coordinates). |
| 236 |
+ |
This will be used in conjunction with the view focal distance, indicated |
| 237 |
+ |
by the length of the view direction vector given in the |
| 238 |
+ |
.I \-vd |
| 239 |
+ |
option. |
| 240 |
+ |
It is not advisable to use this option in combination with the |
| 241 |
+ |
.I pdfblur(1) |
| 242 |
+ |
program, since one takes the place of the other. |
| 243 |
+ |
However, it may improve results with |
| 244 |
+ |
.I pdfblur |
| 245 |
+ |
to use a very small fraction with the |
| 246 |
+ |
.I \-pd |
| 247 |
+ |
option, to avoid the ghosting effect of too few samples. |
| 248 |
+ |
.TP |
| 249 |
|
.BI -dj \ frac |
| 250 |
|
Set the direct jittering to |
| 251 |
|
.I frac. |
