“…The result consists in scalar functions (isopotential surfaces) describing the whole 3D space. Visualization of the isopotential surfaces coming from the interpolation is achieved by the Voronoï diagram method applied to geological objects (Courrioux et al, 2001;Boissonnat and Nullans, 1996). This method transforms isopotential surfaces into discrete sites, which are used to partition 3D space in adjacent cells containing a unique site.…”

“…As an extension of the 2D raster data structure in the 3D space, the voxel model divides the 3D space into nonoverlapping and interconnected geometric elements and uses the voxel information as the basic unit to establish the geological model. Different from the spatial shape simulation of geological structure modeling, in the 3D visualization of the internal geological structure stage, the various heterogeneous properties expressed by voxels have prominent engineering significance 21 – 24 . In addition, this data structure is more convenient for spatial querying, statistics and analysis; therefore, the realization of a 3D geological description using a volume model is attracting increasing interest from the earth science community.…”

In view of the problems in traditional geological modeling methods, such as the insufficient utilization of geological survey data, the inaccurate expression of a stratigraphic model, and the large amount of model data, a 3D geological model cannot be smoothly loaded and rendered on the web end. In this paper, a 3D geological implicit modeling method of regular voxel splitting based on hierarchical interpolation data is proposed. This method first uses the boreholes and geological section data from a geological survey for data conversion and fusion, compares the applicability of different interpolation algorithms through cross-validation research, and uses the best fitting algorithm to interpolate and encrypt discrete points in the formation. Then, it constructs the regular voxels, designs five different regular voxel split types, and divides the voxels. In addition, the data structure design of the voxel split model is implemented, and the irregular voxel metadata structure is analyzed and displayed through Three.js. Using this method, based on the survey data of an area in Zhengzhou, the global workflow from data processing to model construction and visualization is demonstrated. The experimental results show that the model can integrate multisource hierarchical interpolation data; express different stratum structures accurately and smoothly, and can realize the rendering, spatial query and analysis of the internal information of a geological body in a browser.
