stereo3d - render a Raster3D scene as a side-by-side stereo pair
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.
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
The options below are specific to stereo3d. All other options,
e.g. -labels or -gamma 1.2 are passed through to the render program.
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.
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
