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 normalized
(i.e. the original transformation matrix has been applied).
normal3d also reports the total number of objects in the input file by
object type, and gives the array sizes which would be required for the
render program to process the file. It may therefore be used to
determine how large the array sizes in render should be set.
OPTIONS
-ang AA
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.
-expand
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 begining with @) to the new input file without opening them or
normalizing 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
