Texture mapping of geological modeling based on parameterization

How to truthfully and accurately reflects the spatial variation of complex geological bodies is a huge challenge. Most modeling software has made some progress in system functionality and diversity. However, there are still deficiencies in the external appearance and internal quality optimization. In order to improve the quality and effectiveness of geological model mesh, the parameterization method of digital geometric mesh is introduced into the process of geological modeling in this paper. The basic representation method of geological body mesh is studied, and different parameterization methods are designed for different types of meshes. The common geological surface, high curvature geological surface and tunnel surface were verified as examples. The results show that the optimization and quality improvement of three-dimensional (3D) geological models can be realized by using the method presented in this paper, the geometric features of the original mesh are maintained and the degree of distortion is reduced in the process of texture mapping, grid editing, surface reconstruction.
