SCALEGRID Usage
Usage: scalegrid [options]
performs a variety of global operations on a grid
options:
-igrid : name of the grid file to read
-ogrid : name of the grid file to write
-version : prints the version information of the executable
-ver : prints the version number of the executable
-build : prints the build number of the executable
-help, -h : prints this help screen
-dumpvtag : write the volume tags to the screen
-writevtags : write the volume tags to the output grid file
MIRRORING:
-symmetric_x : mirror the input grid about the x = 0 plane.
-symmetric_y : mirror the input grid about the y = 0 plane.
-symmetric_z : mirror the input grid about the z = 0 plane.
SCALING:
-scalefac # : specifies factor to divide all coordinates by Default=1
-scalex # : specified factor to divide x coordinates by Default=1
-scaley # : specified factor to divide y coordinates by Default=1
-scalez # : specified factor to divide z coordinates by Default=1
TRANSLATION:
-dx # : factor to add to x coordinates Default=0
-dy # : factor to add to y coordinates Default=0
-dz # : factor to add to z coordinates Default=0
ROTATION:
-rpx # : x coordinate of point to rotate around Default=0
-rpy # : y coordinate of point to rotate around Default=0
-rpz # : z coordinate of point to rotate around Default=0
-rnx # : x component of vector defining rotational axis Default=0
-rny # : y component of vector defining rotational axis Default=0
-rnz # : z component of vector defining rotational axis Default=1
-rdegrees # : amount to rotate, in degrees.
GENERAL TRANSFORMATION:
-transform : name of the transformation file, if a grid
: transformation is desired. The initial CG of
: the body must be placed on the first line,
: the current CG of the body must be placed on
: the second line, and the quaternions must be
: placed on the third line.
: This operation transforms the grid from time t=t0
: to t = tcurrent.
-revtrans : Reverse the transformation; transform from time
: t=tcurrent to t=t0. If this option is given, the
: -transform option must also be given.
Translations are applied first, then scaling, then rotations,
and then general transformations.
If the -scalefac option is given, it overrides any values given by
-scalex, -scaley, or -scalez.
If given, the transformation file must be in the following (ASCII)
format:
xcginit ycginit zcginit
xcg ycg zcg
