Aiming at the large amount of component data in the 3D dynamic display of the ancient building BIM model, which caused difficulties in information exchange during the protection of the ancient building, a lightweight method of the ancient building BIM model combining with WebGL and IFC standards was proposed. Using WebGL technology to extend the 3D visualization method of BIM models of ancient buildings, providing new technical support for the protection and research of ancient buildings. First define the JSON intermediate file, design the Revit-JSON data interface, make the model support .html and .js format, and improve the visual display method of the web side; use JavaScript to directly call the JSON interactive program of the underlying GPU to improve the web-side rendering effect of the model; Three.js framework realizes the display and interaction of 3D models of ancient buildings on the Web. Taking a typical ancient building as an example to carry out experiments, the method in this paper can reduce the storage volume by more than 70% on the basis of ensuring that the model information is complete, and has a good rendering effect in the browser. The experimental results verify the effectiveness and feasibility of the method.
