Detailed Description
Assigns fibre orientation vectors for papillary muscle structures. Vectors are assigned to be parallel to the direction of the axis of the muscle. To do this we use the "Structure Tensor" method.Definition at line 39 of file PapillaryFibreCalculator.hpp.

Member Function Documentation
| c_vector< double, 3 > PapillaryFibreCalculator::GetRadiusVectorForOneElement | ( | unsigned | elementIndex | ) | [private] |
This method calculates the vector from the centroid of an element to all of the boundary nodes. It returns the shortest of the vectors.
- Parameters:
-
elementIndex The index of the element we are calculating radial vectors for
- Returns:
- The shortest radial vector

| void PapillaryFibreCalculator::GetRadiusVectors | ( | ) | [private] |
This method calls GetRadiusVectorForOneElement() for each of the elements sets the radial vector for each element of the mesh.

| void PapillaryFibreCalculator::SmoothStructureTensors | ( | ) | [private] |
Smoothes the structure tensor components for each papillary element by looping over all other papillary elements, calculating distance geometric distance between the two elements; if it is within a certain limit, include this in the Gaussian kernel
Here mStructureTensors[i] is the 'rough' tensor for each element and mSmoothedStructureTensors[i] is the smoothed tensor for each element
