Morphology

homographic = homography (semi-transparent) = homo + graph + ic

The adjective is a regular formation from the technical noun 'homography', but the specialized mathematical sense limits immediate guessability.

Etymology

The word homographic comes from homo- 'same' and graph 'write', the same parts you see in autograph. A helpful way to remember the math meaning is to think of changing one picture so it 'matches' another, because a homographic transformation maps points so the two views line up.
