Member Function Documentation
◆ applyTransformation()
| applyTransformation | ( | MeshMapperBase | mapper, |
| Structure | ref_structure, | ||
| Structure | other_structure | ||
| ) |
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] mapper A 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_structure The reference mesh [in,out] other_structure On input the imported mesh. On output the mesh with modified coordinates.
◆ doesNonRigid()
|
pure virtual |
- Returns
- true if this transformation applies a non-rigid operation
Implemented in NeutralCoorTransformation, and CoarseRotation.
◆ doesRotate()
|
pure virtual |
- Returns
- true if this transformation applies a rigid rotation
Implemented in NeutralCoorTransformation, and CoarseRotation.
◆ doesTranslate()
|
pure virtual |
- Returns
- true if this transformation applies a rigid translation
Implemented in NeutralCoorTransformation, and CoarseRotation.
◆ generateScriptOfSettingsDefinition()
|
pure virtual |
generates a script string (Lua) that is used to build up this object.
- Returns
- the script code, ends with newline.
- Parameters
-
variable_ident the ident of the Lua variable that contains the MeshMapper object
Implemented in NeutralCoorTransformation, CoarseRotation, CoarseRigidTransformation, and CoarseTranslation.
◆ trafoType()
|
pure virtual |
- Returns
- the type of the transformation
Implemented in NeutralCoorTransformation, CoarseRotation, CoarseRigidTransformation, and CoarseTranslation.
Member Data Documentation
◆ trafo_ref_node_set
| std::pair< string, string > trafo_ref_node_set |
The ident of the reference node set the transformation algorithms will be limited to set up their optimization criterion.
A pair consisting of the part ident as first and the set ident as second member.
