Problems solved by technology

Unfortunately, it is often impossible to produce a high-quality display because such water-based displays often require tightly controlled environments with little or no wind, very low ambient light or dark backgrounds, and high-brightness projectors

Embodiment Construction

[0016] Briefly, the present invention is directed to methods and systems for producing three-dimensional displays using projection screens formed from water. More precisely, rear projection (RP) screens are formed by a mass of water droplets that can be sprayed upward from a pressurized screen forming nozzle (or mist generator) or from an outlet nozzle or manifold of a water curtain forming assembly drip down. An exemplary display system utilizes 3D projection and viewing technology, where 3D content is projected on the back or back surface of a water-based rear projection screen and can be viewed by a viewer or viewer. For example, a suitable 3D projection and viewing technology for projection on a fog screen / curtain is Interference Filter Technology (or "Infitec"), and 3D display systems can use interference filtering in the viewer's glasses and in the projector filters (e.g., dichromatic filters) to deliver right and left eye images / content to the viewer's right and left ...

Abstract

A 3D display system using a flat fog layer or water droplet layer as a rear projection screen. The display system includes a screen generating assembly having nozzles configured to convert a supply of water into a screen of water droplets. The screen is substantially planar and has a front surface facing the viewing area and an opposite rear surface. The display system includes a projection assembly that projects three-dimensional content onto the rear surface. The projection assembly includes a first projector that projects a left-eye image and a second projector that projects a right-eye image. Three-dimensional content may be provided using polarization or other three-dimensional techniques. For example, a first projector includes a first interference filter, and a second projector includes a second interference filter different from the first interference filter, thereby making left-eye images and right-eye images having different bands of the visible color spectrum Images are collectively presented on the back surface.

Description

technical field [0001] This specification relates generally to visual display and projection systems, and more particularly to methods and systems for providing three-dimensional (3D) still or video images in indoor entertainment environments or outdoor entertainment environments, such as amusement parks, sports fields, shopping malls, etc., which may have A location for a large audience. Background technique [0002] There is a growing need to provide entertainment in outdoor environments such as large urban parks, amusement or theme parks, sporting events, outdoor concerts or other settings where large crowds gather. For example, it is known to provide laser or light-based projections as part of outdoor concerts. Among other things, it is popular to provide fireworks displays to entertain the public in a park setting or during or after a baseball, football, or football game. [0003] In many cases, it is often desired that the show being presented is so unique and exciti...
