INVLIB::SourceMorph is the C++ peer of mne-python's mne.compute_source_morph + SourceMorph.apply. It consumes the sparse vertex-to-vertex interpolation matrix produced by FSLIB::MNEMorphMap (nearest-neighbour on the subject sphere) and stores it together with the from/to vertex lists so a precomputed morph can be re-applied to many source estimates from the same subject pair without re-doing the surface interpolation. The resulting morphed estimate carries the to subject's vertex list and time axis untouched, making it directly comparable to estimates that were inverse-solved natively on the target subject.
