bool itk::fem::RobustSolver< VDimension >::m_UseInterpolationGrid

private

Use interpolation grid to initialize the landmarks or not. If use the grid, make sure the landmark is the grid point. The landmarks (feature points) are usually the grid points if these landmarks come from a feature point detection algorithm applied on an image.
