Re: [IMP-dev] [IMP-commits] r903 - in trunk/modules/misc: include pyext src test/transformation
Couple quick comments: - we are mostly avoiding abbreviations, so get_trans should probably be "get_translation". It is a bit weird just having that (and no get_matrix or "get_rotation") - The function on Rotation3D shouldn't be mult (since it isn't necessarily multiplication as it is not necessarily a matrix). "transform" taken from Transformation3D or "rotate" are probably the best options. - I still don't like exposing the various methods on Matrix3D having to do with rotation. I think they should be hidden (and some classes made friends if outside classes need them).
Otherwise, looks good. THanks.

Actually, now that I think about it, we probably can't use them in anything in core until they get moved into the kernel, so we are probably still waiting on Ben. Especially since rotation and and all would be part of the TransformedPairScore interface.
