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
