NAME

       avs2ps - convert AVS image input on stdin to monochrome PostScript on stdout

SYNOPSIS

	  avs2ps [-b] [-dpi xxx] < infile.avs > outfile.ps

       avs2ps converts a 24-bit color image file in AVS format into a dithered monochrome PostScript image with the same number of pixels as the
       input file.  avs2ps may be used as a filter for the output of the render program to produce a PostScript file directly.

       avs2ps is machine independent, and does not impose restrictions on the tile size in the original image.	It supersedes the programs mol-
       ras3d and hdither in the viewtools package.

EXAMPLES

       Produce an unbordered black & white image suitable for printing on a 300 dpi PostScript printer.

	    render < infile.r3d | avs2ps > image.ps

       Add a border, and prepare image for a 400dpi printer

	    render < infile.r3d | avs2ps -b -dpi 400 > image.ps

OPTIONS

       -b

       Draw a border around the figure.  By default avs2ps will produce a borderless image 0.5 inch in from the bottom left of the page.

       -dpi xxx

       By default avs2ps writes header records into the PostScript output file which are correct for a 300dpi printer (e.g. an HP IIIsi).  If
       there is a mis-match between the header records and the actual resolution of the printer the image quality is substantially degraded.  This
       option allows one to specify a different printer resolution (e.g. -dpi 400 for a Next printer, or -dpi 95 for GhostScript on a 1280x1024
       workstation screen).

DESCRIPTION

       avs2ps converts the input stream to a grey scale image and then applies an empirical algorithm for dithering and error propagation to pro-
       duce a monochrome output image.

NAME

       normal3d - apply transformation matrix in Raster3D input file

SYNOPSIS

       normal3d [options] < infile.r3d > normalized.r3d

DESCRIPTION

       normal3d reads a Raster3D input file from stdin, applies any coordinate manipulations specified in the header, and writes the modified file
       to stdout.

       The output file from normal3d describes exactly the same image as the original input file. Header records are left unchanged except for the
       transfomation matrix (which becomes the identity matrix) and the format specifiers (which are set to *). The -h flag suppresses all header
       records in the output file.  All objects in the input file are also in the output file, but their coordinate descriptions have been normal-
       ized (i.e. the original transformation matrix has been applied).

OPTIONS

       -ang AA

       Only relevant for generating stereo pairs. By default stereo separation is created using a shear operator. The -ang option instead intro-
       duces an angular separation by rotating the left and right eye images by +/- AA degrees with respect to the original view angle.

       -expand

       In-line and normalize all instances of file indirection in the input stream.  This results in a single input file containing no file indi-
       rection.  The default is to simply copy file indirection lines (those begining with @) to the new input file without opening them or nor-
       malizing their contents.

       -h

       Suppress header records in output.  This option is useful for producing files which describe only part of a scene, and which are to be
       later combined with descriptor files

       -size HHHxVVV

       Force the image size to HHH pixels horizontal and VVV pixels vertical.

       -stereo [scratch]

       This option causes the program to produce two additional files, left.r3d and right.r3d, that contain header records suitable for rendering
       the normalized object desctiption file as a side-by-side stereo pair.  This option always suppresses header records in the primary output
       file.  If a scratch directory name is given, it is prepended to give output files {scratch}_left.r3d and {scratch}_right.r3d
