Name: WlzCMeshTrExpansion - computes strain tensors for the given conforming mesh transform.

Synopsis

WlzCMeshTrExpansion [-h] [-i] [-E|T|V] [-I] [-L] [-n] [-o<out file>]
                    [<input file>]

Options

-h	Help, prints usage message.
-i	Output spatial domain image not a conforming mesh.
-I	Use transform inverse.
-E	Use maximum strain tensor eigenvalue.
-L	Use kriging rather than barycentric interpolation./td>
-T	Use strain tensor trace.
-V	Use element volume (default).
-n	Normalise expansion factors./td>
-o	Output object file.

Description

Examples

Computes the expansion of each element of the given mesh transform. The expansion may be output as a mesh with scalar values attached to the mesh elements or as a 2D spatial domain object with image values. If requested the image values are normalised so that: [0:max(abs(min),abs(max))] -> [128:25] By default all files are read from the standard input and are written to the standard output.

WlzCMeshTrExpansion -o meshexp.wlz -i -n meshtr.wlz

Creates a new spatial domain (image) object (written to meshexp.wlz) with the mesh expansion factors normalised to fit within the unsigned byte range and with 0 to the value 128.
