| double | lsInternal::squareSumSquare (It begin, It end) |
| | Returns the squared sum square for values in the range [start, end[.
|
| template<class It> |
| double | lsInternal::rootSumSquarePow3 (It begin, It end) |
| | Returns the root sum square to the 3rd power for values in the range [start, end[.
|
| template<class T, std::size_t N> |
| double | lsInternal::meanCurvature2D (std::array< T, N > funcValues) |
| | Mean curvature formula for implicit surfaces in 2D, the passed array should contain the function values in the following order: (F_x, F_y, F_z, F_xx, F_yy, F_zz, F_xy, F_yz, F_zx).

| template<class T, std::size_t N> |
| double | lsInternal::gaussianCurvature3D (std::array< T, N > funcValues) |
| | Gaussian curvature formula for implicit surfaces in 3D, the passed array should contain the function values in the following order: (F_x, F_y, F_z, F_xx, F_yy, F_zz, F_xy, F_yz, F_zx).

| template<class It, class T = typename It::DomainType::ValueType> |
| std::array< T, 9 > | lsInternal::smallStencilFromIterator (It &it, const double gridDelta) |
| | Fills a std::array with differential values calculated from neighbour values. This stencil only uses direct neighbours for fast calculation of the differentials.
|
| template<class It, class T = typename It::DomainType::ValueType> |
| std::array< T, 9 > | lsInternal::bigStencilFromIterator (It &it, const double gridDelta) |
| | Fills a std::array with differential values calculated from neighbour values. This stencil also uses diagonal neighbours to achieve a higher accuracy.
|
| template<class It, class T = typename It::DomainType::ValueType> |
| T | lsInternal::meanCurvature (It &it, bool bigStencil=false) |
| | Calculates the Mean Curvature of the level set function from a suitable hrle iterator. Requires an iterator that is big enough to calculate second order derivatives(e.g. hrleBoxIterator or hrleCartesianPlaneIterator).
