7 + .B "[ view options ]"
8   .B distance
9   .br
10   .B vwright
11 + .B "[ view options ]"

13   .SH DESCRIPTION
14 < .I Vwright
15 < shifts a RADIANCE view from a picture or view file given on the standard input
14 > In the first form,
15 > .I vwright
16 > shifts a RADIANCE view
17   the specified distance to the right, putting out a complete set of
18   view parameters in a single line on the standard output.
19   This utility is most often used to compute a right-eyed view from
20   a left-eye view for stereo imaging.
21   .PP
22 + If no options are specified on the command line,
23 + .I vwright
24 + reads a view from its standard input.
25 + .PP
26   The
27   .I distance
28   given is in world coordinate units.
# Line 31 | Line 38 | For a given prefix
38   the constant names are as follows:

41 < Nt:     view type ('v'==1,'l'==2,'a'==3,'h'==4,'c'==5)
41 > Nt:     view type ('v'==1,'l'==2,'a'==3,'h'==4,'c'==5,'s'==6)
42   Npx:    view point x value
43   Npy:    view point y value
44   Npz:    view point z value
# Line 62 | Line 69 | To start
69   .I rpict(1)
70   on a view .06 meters left of the view in the file "right.vf":
71   .IP "" .2i
72 < rpict `vwright -.06 < right.vf` scene.oct > right.pic &
72 > rpict `vwright -.06 < right.vf` scene.oct > right.hdr &
73   .PP
74   To move the
75   .I rad(1)
76   view named "left" 2.5 inches to the right
77   and render from there:
78   .IP "" .2i
79 < rad -v "right `rad -n -s -V -v left examp.rif | vwright 2.5`" examp.rif &
79 > rad \-v "right `rad \-n \-s \-V \-v left examp.rif | vwright 2.5`" examp.rif &
80   .PP
81   To pass a view to
82   .I rcalc
83   for conversion to some other view:
84   .IP "" .2i
85 < rcalc -n -e `vwright orig < orig.vf` -f viewmod.cal -o view.fmt > new.vf
85 > rcalc \-n \-e `vwright orig < orig.vf` \-f viewmod.cal \-o view.fmt > new.vf
