Visualization Technology of Underground Pipe Network Based on Cesium
The urban drainage pipe network serves as the cornerstone for ensuring the safe and stable functioning of a city. However,con-ventional two-dimensional graphic techniques fall short in capturing the intricate spatial distribution of underground pipelines. In light of this,a novel modeling approach leveraging Cesium is proposed to automatically generate three-dimensional 3DTiles models of underground pipe networks using DWG data. The methodology encompasses several key steps,including meticulous data preprocessing to eliminate erroneous en-tries,creation of the pipe network model,data coordinate transformation,data segmentation to enhance model generation efficiency,software de-velopment enabling automated generation of intermediate model files,and model slicing for ultimate visualization. The outcomes of the study demonstrate the rapid generation of 3DTiles models from DWG data,facilitating the effective visualization of intricate underground three-di-mensional structures. This breakthrough offers valuable technical support and serves as a methodological reference for subsequent research on Cesium-related investigations in the field of underground spaces.
