Header and Body 3


A 3D model is constructed by importing or generating a dataset representing a surface and rendering the same by 3D printing or other means of physical formation through any series of fabrication steps. The final embodiment of the 3D model is composed of hollow or solid, transparent or translucent base material upon which a light-diffusing surface is applied or formed (e.g., as a result of a coating or surface profiling).  A projection device is then mounted in a configuration so that distinctive patterns of light are directed, possibly through the transparent base surface, toward the diffuse surface of the 3D model to distinctively illuminate portions of the model.  This distinctive illumination may be applied in selective fashion to highlight particular spatial features of the physical model or visually express spatial distinction even where no corresponding feature exists in the physical model.
