Design and Implementation of 3D Visualization System

A smart park geographic information system based on network geographic information technology is proposed. TIN mode was selected for terrain visualization. While using MySQL database, it can also use HTML, JavaScript, CSS, Ajax, Echarts and other programming technologies to complete the processing of 3D model data, scene roaming, park information display, platform query and other work. The FR algorithm is improved based on entity structure and entity attributes. This method can not only realize 3D image generation faster, but also show the relationship between entity nodes and entities in 3D image better. The effectiveness and scalability of the proposed algorithm are proved by 3D visualization experiments. The system can meet the requirements of image spatial data management and 3D visualization business application.
