Morphology

nonrigid = rigid (transparent) = non + rigid

The technical sense is a direct extension of 'not rigid' to models or transformations that permit local deformation, which learners can infer from the components.

Etymology

Nonrigid comes from non- 'not' and rigid 'stiff'. A helpful image is soft clay or a rubber sheet that can bend or stretch in places instead of moving as one hard piece. So in computing a nonrigid change lets a shape bend or stretch locally, not just move or turn as a whole.
