Where it started

Explore ParaViewGeo, a powerful open-source visualization engine tailored for mining geomechanics, providing time support, data analysis, animation, and customizations like pan, zoom, rotate. Benefit from features such as surface reconstruction and cross-section loading to enhance mine planning efficiency. ParaViewGeo supports both 2D and 3D files and offers extensive object support for detailed geomechanical analysis. Discover its capabilities for drill hole visualization, volume tetrahedralization, and more.
