class DataResultTransformation : public RefCountedObject

Transformation results for all parts in the geometry.

The DataResultTransformation holds a collection of matrices, each setting the transformation for the belonging part.


The number of parts in the transformation result and in the geometry must be the same.

Transformation matrices can be added using addPart(). Get the number of part matrices in the transformation result with partCount() and accessed individual part matrices by calling part()

with the requested index.

All part matrices can be removed using


Transformation result visualization can be toggled on or off in the model specification (UnstructGridModel::modelSpec()).


Note! The class is reference counted and can be shared between multiple result groups. Remember that since this object is reference counted it should never be created on the stack.


Example of how to add a node based scalar result to a geometry consisting of only one triangle.

Create the DataResultScalar object with a unique id and node based result mapping.

cee::PtrRef<cee::ug::DataResultTransformation> transformationResult = new cee::ug::DataResultTransformation();

Create the transformation matrix.

cee::Mat4d partMatrix;
partMatrix(0, 3) = 1.0;
partMatrix(1, 3) = 1.0;

Add the transformation part to the result. The result must contain the same number of parts as the corresponding geometry.


For each geometry there is a result group binding the geometry and results. Add the transformation scalar to the state (DataState) for the corresponding geometry (DataGeometry) geo


The result is now created and added to the model. To tell the model to use this result, you must toggle transformation usage in the model’s model specification.
