The Research Of Display Based On 3D Entity Sandbox

In recent years,along with the rapid development of 3D display technology,people’s understanding of the world is no longer satisfied with the traditional audio-visual feeling,but put forward higher requirements.Realistic and realistic 3D display technology has become the current research focus.The research on the display of 3D sandbox is based on the entity sandbox,and the LED is displayed on the top and side of each pillar of the entity sandbox mechanism.We show the image data on LED to make the display effect of 3D entity sandbox more lifelike image.The research of this paper mainly includes the acquisition and pretreatment of multi-source data,the design of data structure and the design and implementation of 3D sandbox display scheme.The multi-source data is transmitted to the host computer through the network communication.Then multi-source data is preprocessed,which includes restoring the elevation data to the original size of the sandbox matrix,and the image data of the different directions of the display area is preprocessed by bilinear interpolation algorithm.Meanwhile we extract RGB of image pixels and store data to different files.At the same time,a data structure combined with matrix and linked list is designed to the research display of the sandbox,which makes the design scheme of the sandbox can store,process and read the data quickly,accurately and reliably.Secondly,top mode and panorama mode are proposed.The display structure of sandbox is obtained by using elevation data.Then,three kinds of side color information filling schemes are proposed for panorama mode.The different color information filling schemes are implemented and the data structure of sandbox display is obtained.Finally,based on OpenGL technology platform we preview the 3D sandbox effect,and verify that the correctness and effectiveness of the display research.
