As urban space becomes more and more crowded, more and more urban buildings, transportation, and pipe network systems continue to expand from the Earth's surface to the interior of the Earth, which puts new demands on space information display technology. As underground use scenarios have become more and more common in engineering, research, and ordinary people's lives, as well as browser technology is lightweight, cross-platform, and easy to use, Therefore, research on Web-based cross-space information display technology has positive significance for both research and production. Based on the research of Three.js, Cesium and other three-dimensional spatial information display technology, this paper selects Cesium open source JavaScript library as the platform to explore, and the problem that the platform can not realize the display of the internal space information of the earth is discussed, and a complete solution is proposed. The scheme improves the three-dimensional view from the surface transparency, the internal perspective of the Earth and the image cropping, and realizes the Cesium platform which improves the comprehensive browsing and consolidation of the three-dimensional entities across the space. Subsequently, based on the secondary development of the improved platform, the underground tunnel display system of B/S structure was initially realized. The system simulated the tunnel drilling, tunneling and completion operation, the feasibility of the cross-space information display technology in the Web environment proposed in this paper is verified.
