Virtual Reality Modelling of Garden Geography and Geology Based on 3D Modelling Technology

The work of 3D garden geo-geological modelling is very tedious and complicated, in order to reduce the labour intensity of the operators and improve the visualization effect of the model. This article proposes a method for 3D stratum visualization based on the combination of limited Delaunay triangulation and OpenGL. We can use the limited triangulation algorithm to generate stratum surface triangulations with any boundary shape, any size, or with multiple holes. At the same time, the paper uses OpenGL’s object picking mechanism to realize the visualization management of drilling data and human-computer interaction stratum modelling. Finally, we applied the model to garden geology, and the results showed that the system can quickly and accurately construct a three-dimensional model of the stratum. At the same time, the model realizes the three-dimensional visualization processing of garden geology.
