A multi-layered display with water drops

摘要: We present a multi-layered display that uses water drops as voxels. Water refract most incident light, making them excellent wide-angle lenses. Each 2D layer of our can exhibit arbitrary visual content, creating layered-depth (2.5D) display. Our system consists single projector-camera and set linear drop generator manifolds are tightly synchronized controlled using computer. Following the principles fluid mechanics, we able to accurately generate control so that, at any time instant, no two occupy same projector pixel's line-of-sight. This is combined with an algorithm for space-time division light rays. prototype has up four layers, each consisting row 50 be generated 60 Hz. The effective resolution 50x vertical-resolution x number layers. show how this used text, videos, interactive games.
