Research On 3D Display Of LED Body

Currently, three-dimensional stereoscopic display technology has become an important researching direction in the areas such as computer graphics etc. Body three-dimensional display different from two-dimensional nature, it is neither a traditional two-dimensional display, nor the cinema3D movies or3D TV now, which completely broke the plane’s limition. A three-dimensional object is showed in three-dimensional space, which make it feel more real three-dimensional.From the two-dimensional planar LED screen display research, we simply describes how to control LED display by experimental examples. Basing on the two-dimensional display, and starting from the three-dimensional display theory, we use LED to design the LED display body in three-dimensional space, and accomplish the LED body three-dimensional display system. This static three-dimensional LED display device is arranged in three-dimensional matrix LED display media, through addressing and independently controling each LED to restore the true three-dimensional image. The resulting image is very similar with the objects our naked seen with, and the observer can observe at any angle.Another improvement of this article is about the three-dimensional image data sources. Using the powerful of OpenGL graphics library function to create the three-dimensional images is very complicated and spend more time and so on, so we directly use a graphics software to finish the map and then enter it to the OpenGL scene. This paper studies the entering and extraction of two common three-dimensional image IGES and3DS. It also studies the dynamic display of three-dimensional display algorithms, including translation, rotation, scaling and complex transformation, making the effect more colorful display. Finally, it is a brief introduction to implement the entire hardware system.
