.TH NORMAL3D 1 "12 Dec 2010" "Raster3D"
.SH NAME
normal3d - apply transformation matrix in Raster3D input file
.SH SYNOPSIS
normal3d [options] < infile.r3d > normalized.r3d
.SH DESCRIPTION
.PP
\fInormal3d\fP
reads a Raster3D input file from stdin, applies any coordinate manipulations
specified in the header, and writes the modified file to stdout.
.PP
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
normalized (i.e. the original transformation matrix has been applied).
.SH OPTIONS
.B "-ang AA"
.PP
Only relevant for generating stereo pairs. By default stereo separation
is created using a shear operator. The -ang option instead introduces
an angular separation by rotating the left and right eye images by +/- AA
degrees with respect to the original view angle.
.B "-expand"
.PP
In-line and normalize all instances of file indirection in the input stream.
This results in a single input file containing no file indirection.
The default is to simply copy file indirection lines (those beginning
with @) to the new input file without opening them or normalizing their
contents.
.B "-h"
.PP
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
.B "-size HHHxVVV"
.PP
Force the image size to HHH pixels horizontal and VVV pixels vertical.
.B "-stereo [scratch]"
.PP
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
