Abstract

Systems and methods are provided for presenting visual media on a structure having a plurality of unordered light sources, e.g., fiber optic light sources, light emitting diodes (LEDs), etc. Visual media can be created based on a computer model of the structure. Images of the structure can be analyzed to determine the location of each of the light sources. A lookup table can be generated based on the image analysis, and used to correlate pixels of the visual media to one or more of the actual light sources. A visual media artist or designer need not have prior knowledge of the order/layout of the light sources on the structure in order to create visual media to be presented thereon.

Background

TECHNICAL FIELD

The present disclosure relates generally to displays, and more particularly, to generating media on three-dimensional (3D) displays having unordered lights sources.DESCRIPTION OF THE RELATED ART

Media, such as electronic images, video, etc. may be presented on displays such as liquid crystal displays (LCDs), light-emitting diode displays (LEDs), plasma display panels (PDPs), and the like. Such displays act as an output device for the presentation of such media. Generally, such displays output media through an array of light sources. For example, in the case of LEDs, an array of light-emitting diodes output light making up a portion of the media being presented. For example, in the case of LCDs or PDPs, a display can be made up of pixels, each outputting red, blue, or green light that can be switched on or off to generate a moving picture.BRIEF SUMMARY OF THE DISCLOSURE

In accordance with one embodiment, a computer-implemented method comprises generating a computer model of a display surface, where the display surface comprises an unordered array of light sources. The computer-implemented method further comprises generating visual media to be presented on the display surface using the computer model of the display surface, and generating a map of light emission locations on the display surface. Moreover, the computer-implemented method comprises generating correspondence information between the computer model of the display surface and the map

Claims

1. A computer-implemented method, comprising: generating a computer model of a display surface, the display surface comprising an unordered array of light sources; generating visual media to be presented on the display surface using the computer model of the display surface; generating a map of light emission locations on the display surface; generating correspondence information between the computer model of the display surface and the map of light emission locations on the display surface; and transmitting signals representative of the visual media to one or more light sources of the unordered array of light sources based on the correspondence information. 12. A system, comprising: a processor; and a memory unit operatively connected to the processor, the memory unit including computer code configured to cause the processor to: generate a map of light emission locations on a display surface, the display surface comprising a plurality of unordered light sources corresponding to the light emission locations; correlate pixels of a computerized visual media to the light emission locations on the display surface based on a lookup table comprising information reflecting the map of light emission locations; and transmit signals representative of the computerized visual media to one or more light sources of the plurality of unordered light sources based on the correlation of the pixels to the light emission locations. 20. The system of 12, wherein each of the one or more light sources comprises a networked and addressable light source.
