};Description
DVmirror generates a mesh that is the mirror image of the input mesh. "Mirror image" means that the mesh is mirrored about the X, Y, and/or Z plane. You can control each independently. It accomplishes this by modifying the xform transformation matrix object associated with a field. Mirroring is useful for visualization of axis symmetric problems.
Input
Floating parameters that define the transformation to apply to the X, Y, and Z axes of the mesh. The default for all is -1.0. If you change it to 0.0, that axis will not be mirrored.
Output
The output is a reference a new object that is the merge of the new transformation matrix plus a reference to the original input field.
