vwright

VWRIGHT(1)						      General Commands Manual							VWRIGHT(1)

NAME

       vwright - normalize a RADIANCE view, shift it to the right

SYNOPSIS

       vwright [ view options ] distance
       vwright [ view options ] name

DESCRIPTION

       In  the	first form, vwright shifts a RADIANCE view the specified distance to the right, putting out a complete set of view parameters in a
       single line on the standard output.  This utility is most often used to compute a right-eyed view from a left-eye view for stereo imaging.

       If no options are specified on the command line, vwright reads a view from its standard input.

       The distance given is in world coordinate units.  A negative value indicates a shift to the left rather than the right.

       The second form substitutes a name prefix in place of the shift distance, and produces constant assignments on the standard output suitable
       for passing directly to rcalc(1).  For a given prefix N, the constant names are as follows:

       Nt:  view type ('v'==1,'l'==2,'a'==3,'h'==4,'c'==5,'s'==6)
       Npx: view point x value
       Npy: view point y value
       Npz: view point z value
       Ndx: view direction x value (normalized)
       Ndy: view direction y value (normalized)
       Ndz: view direction z value (normalized)
       Nd:  view focal distance
       Nux: view up vector x value (normalized)
       Nuy: view up vector y value (normalized)
       Nuz: view up vector z value (normalized)
       Nh:  view horizontal size
       Nv:  view vertical size
       Ns:  view shift
       Nl:  view lift
       No:  view fore clipping distance
       Na:  view aft clipping distance
       Nhx: derived horizontal image vector x value (normalized)
       Nhy: derived horizontal image vector y value (normalized)
       Nhz: derived horizontal image vector z value (normalized)
       Nhn: derived horizontal image vector multiplier
       Nvx: derived vertical image vector x value (normalized)
       Nvy: derived vertical image vector y value (normalized)
       Nvz: derived vertical image vector z value (normalized)
       Nvn: derived vertical image vector multiplier

EXAMPLES

       To start rpict(1) on a view .06 meters left of the view in the file "right.vf":

	 rpict `vwright -.06 < right.vf` scene.oct > right.hdr &

       To move the rad(1) view named "left" 2.5 inches to the right and render from there:

	 rad -v "right `rad -n -s -V -v left examp.rif | vwright 2.5`" examp.rif &

       To pass a view to rcalc for conversion to some other view:

	 rcalc -n -e `vwright orig < orig.vf` -f viewmod.cal -o view.fmt > new.vf
