Raster3D                                           19 Dec 2010                                       STEREO3D(1)

       If the following line would render a single image:

             render -tiff single.tiff < input.r3d

       then the following line would render the same scene as a stereo pair instead:

             stereo3d -tiff stereo.tiff < input.r3d

       stereo3d - render a Raster3D scene as a side-by-side stereo pair

       The options below are specific to stereo3d.  All other options, e.g. -labels or  -gamma  1.2  are  passed
       through to the render program.

       -angsep

       By  default  the  stereo  effect is generated by a shear operation.  The -angsep option creates stereo by
       using angular separation instead.  Neither option is perfect: the default handles shadows badly, and  the
       -angsep option blurs specular highlights.

       -border

       By default the left and right images are placed next to each other with no intervening space and no frame
       around  them.   The  -border  option  requests a 4 pixel wide black border separating and surrounding the
       component images.

          stereo3d [options] [-png  [outfile.png ]] < infile.r3d > outfile.png
          stereo3d [options]  -tiff [outfile.tiff]  < infile.r3d > outfile.tiff

       stereo3d is a shell script that renders a single Raster3D input file as a side-by-side stereo pair.

       stereo3d  uses  the Raster3D utilities normal3d and render, and the ImageMagick image processing package.
       Intermediate scratch files are created in directory TMPDIR, if defined, otherwise in /usr/tmp.

       The right eye and left eye views are separately rendered, optionally given black borders, and  merged  to
       form a single side-by-side stereo pair.

       Input  is  from stdin, output is to stdout unless a filename is given as an argument to the -png or -tiff
       options.
