Este tutorial muestra el procedimiento completo para convertir una unidad geológica como una malla Leapfrog (*.msh) al formato VTK (Visualization Toolkit) utilizando Python y GemGIS. Sigue estos pasos para transferir de manera eficiente tus datos geológicos para su visualización avanzada, análisis y comparación con resultados de otros modelos.
