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).

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
