Abstract: Three-dimensional visualization technology plays an important role in the dynamic analysis of geological disasters. In order to improve the understanding of geological disasters such as landslides and debris flows and predict their potential hazards，a three-dimensional visualization application based on C# and Direct3D technology has been developed. This application is based on the theory of deep integral contin⁃ uum mechanics and combines the disaster dynamics calculation software Massflow to simulate the dynamic process of geological disasters. It can present geological disaster information in the form of three-dimension⁃ al images to achieve data visualization，including the real-time animation display of information such as the height and speed of the moving body of geological disasters at different times. By comparing with actual cas⁃ es，the simulation results show a high degree of consistency，verifying the accuracy and reliability of this technology in describing the potential hazard range during the movement of landslides and debris flows. In addition，this software has potential application value in disaster early warning，providing a new tool for di⁃ saster early warning and science popularization. It is of great significance for the prevention of geological di⁃ sasters and can offer strong technical support for research and practice in related fields.
