0.1.0

Date

August 2012

The FIFF coordinate-frame world is a small zoo (FIFFV_COORD_DEVICE, FIFFV_COORD_HEAD, FIFFV_COORD_MRI, FIFFV_COORD_HPI, FIFFV_COORD_RAS, ...) and any forward / inverse computation must move points and orientations between them. FiffCoordTrans wraps one labelled affine: the 3x3 rotation rot, the 3-vector translation move, the precomputed inverse, and the integer from / to frame identifiers from fiff_constants.h.

The class also publishes the small algebra needed at the call sites: multiplication, inversion, and the convenience helper that picks the right transform out of a FiffCoordTransSet by (from, to) pair. Surface-compatible with the mne.transforms.Transform object in MNE-Python.
