基于标量坐标的复杂地质表面模型隐式生成方法
Implicit generation of complex geological surface models based on scalar coordinates
摘要
Abstract
The construction and presentation of a geological modelprove to be ahot topic and challenge in research on 3D geological modelling.Given the large scale,involvement of complex surfaces,and insufficient geological constraints of geological body data,this study achieved the rapid construction of a large-scale geological surface model using the domain decomposition-based implicit generation method.Initially,implicit functionswere constructed by taking radial basis functions as the kernel functions.Then,the distribution functions of various domainswere solved in parallel usinganoverlapping domain decompositionmethod,reducing the spatiotemporalcost and accelerating the solving process.Subsequently,normal vectors were extracted to generate control pointsand formconstraints on sur-face fluctuation,thereby effectively controlling the model boundaries.The experimental results indicate that the method proposed in this study can significantly improve the efficiency associated with the solving of distribution functionswhile ensuring the high quality of the model.This study effectively solves the problem of balance between efficiency and precision in geological modeling and provides meth-odological support for the refinement of geological surfaces.关键词
