STEREO3D

SYNOPSIS

stereo3d is a shell script that renders a single Raster3D input file as a side-by-side stereo pair. The resulting image is placed in file stereo.tiff. stereo3d render_input_file.r3d stereo3d uses the Raster3D utilities normal3d and render, and the utility programs identify, mogrify, and montage from John Cristy's ImageMagick image processing package. Three intermediate files are produced by normal3d:

stereo3d.tmp - normalized version of the input file
left.r3d - header records for left eye view
right.r3d - header records for right eye view

The two views are separately rendered to yield images left.tiff and right.tiff (deleted upon completion), given black borders, and merged to form a single side-by-side stereo pair stereo.tiff.

EXAMPLES

If the following line would render and display a single image: render -tiff single.tiff < input.r3d; display single.tiff then the following line would render and display the same scene as a stereo pair instead: stereo3d input.r3d; display stereo.tiff NB: The output image is always called stereo.tiff; there is no provision at present to specify some other name.

ENVIRONMENT

This script requires TIFF support in render, the unix utility nawk, and the ImageMagick image processing package. The three intermediate files listed above are created each time the script is run. Any exiting files named left.tiff, right.tiff, or stereo.tiff will be destroyed.
