abstract = {Interactive 3D HTML models and visualizations of geological structures derived from classic surface geological
information have been developed, for the first time, in a Python environment, using the key case of the tectonic
Mula sheets in the Betic Cordillera (southern Spain). These models were performed through several steps: a
geological 2D sketch map, creating equispaced geological cross-sections, 3D topography, a complete 3D model,
and detailed 3D block diagrams. The result of the extrapolation of the equispaced geological cross-sections and
their integration with the geological map into a 3D geological model shows the thrust-faulted and contractionally
folded structure of the entire area, which affects the Cretaceous to Lower Miocene succession. The faults (strikeslip and normal) present in the tectonic thrust sheets are also represented. Three detailed 3D HTML blocks of
illustrative regions within the modeled area were also created. For the 3D modeling, B´ezier curves/surfaces as
well as linear interpolation were used, as geological (stratigraphic and tectonic) contacts and surfaces between
different stratigraphic units can be expressed geometrically with these tools. Compared to commercial alternatives, our software offers three key advantages: free user-friendly solutions, browser-compatible 3D models, and
open-source software. The 3D visualization of stratigraphic-structural architecture enables predictive interpretations with applications in environmental and economic geology (e.g., groundwater, geotechnical studies,
mining research, etc.). Moreover, 3D visualization and modeling provide valuable insights into geological
phenomena, benefiting both the scientific community and society at large. Furthermore, advances in interactive
3D visualization bridge the gap between cutting-edge geological research and public understanding, enhancing
social awareness.},
