NAME

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

SYNOPSIS

          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.

EXAMPLES

       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

OPTIONS

       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.
