Abstract: This paper focuses on 3D geological modeling software. Aimed at the problem of the complex operation of existing software, software designed to lower the usage threshold has been developed. This software is built on the technologies of C++, Qt, and VTK, and adopts a user-centered design concept. The main interface, basic shape creation, fault model establishment, and value assignment functions of the software are introduced in detail. The main interface has clear functional partitions and is easy to operate. The basic shape creation function allows users to create various types of shapes simply. The fault model establishment function enables users to generate a fault model by just inputting key parameters. The value assignment function facilitates users to manage and assign attribute values to geological strata. Practical verification shows that the software has significant advantages in terms of operational convenience, providing an efficient modeling tool for professionals in relevant fields and being of great significance for promoting the application of 3D geological modeling technology. Meanwhile, it is also pointed out that the software needs improvement in terms of performance when dealing with large-scale data and function expansion, which provides a direction for future research.
