 applyTransformation  ( [MeshMapperBase](class_mesh_mapper_base.xhtml)  *mapper*,    [Structure](class_structure.xhtml)  *ref\_structure*,    [Structure](class_structure.xhtml)  *other\_structure*   )   inherited 

Applies the coordinate transformation to the other\_structure.

If a transformation reference node set has been defined, only those nodes included in the sets will be used to determine the transformation matrix. Otherwise all nodes of both structures will be used for the determination algorithm. Nevertheless, the transformation itself will be applied to all nodes of the other\_structure. It might also occur, that the reference node set cannot be found in the other\_structure. In such a case, the reference node set will be projected onto the segments of the other\_structure and used as virtual node set.

Parameters \[in\]mapperA back reference to the current mesh mapper. This one might be needed if a defined reference node set cannot be found in the other\_structure \[in\]ref\_structureThe reference mesh \[in,out\]other\_structureOn input the imported mesh. On output the mesh with modified coordinates.
