Interlinked Signage on hilly terrains

摘要

Signage is used as one-way communication tool between the static landscape and dynamic people. On plains, which are planar by definition, ordinary two-dimensional signage suffices well. Problem arises on hills which are three-dimensional in structure. For hills, two kinds of signage have been designed: the ordinary 2-D ones loaded with more data and mutually transferring dynamic updates & the specialized 3-D signage created from solid modelling of terrains.
