module DVconcat_xform {

Description

DVconcat_xform concatenates the xform transformation matrix of two inputs, thus "adding" one transformation on an object to another. For example, one field may be rotated, another scaled, and the output will be rotated and scaled.

Input

Input&xform_in1 &xform_in2

Two xform transformation matrices. These can usually be obtained from the Grid of a field.

Output

xform_out

The new, concatenated transformation matrix.
