In the field of geotechnical engineering, creating and successfully cutting a three-dimensional geological model is a crucial task for digital and visual analysis. However, using commonly available software for 3D model cutting can be time-consuming. Moreover, mainstream cutting algorithms have limitations that can impact real-time performance, such as high computing requirements and complex testing. To address these issues, with the help of the Three.js library, based on the stencil test function module and the cutting operation, this paper presents a real-time rendering closure method for the continuous cutting of a TIN model. This method is implemented by object-oriented programming. When using this method to cut a model, there is no need to intersect and triangulate each point of the section, thereby improving real-time performance. Furthermore, this method enables the real-time rendering of a closed section in the hollow model, resolving issues related to displaying hollow sections in a multilevel TIN geological model, which can serve as another exploratory approach for closed cutting of internal hollow models. The method was applied to a project in southern China and yielded positive results. The time consumption of this cutting process was less than 1 s, and compared to the 3dsMax method under the same conditions, it reduced the time consumption by 6.85 s and improved efficiency by 87%. It can effectively support visual analysis tasks for similar processes, such as smart mines, oil and gas resource distribution, and internal visualization analysis of mechanical parts.
