Locally Varying Anisotropy

Locally varying anisotropy (LVA) lets estimation and simulation follow the geology:

• Local angles from meshes and solids: estimate_angles extracts normals from mesh faces and transfers local continuity directions to the modeling grid.
• Local angles from structural data: the same tool derives locally varying angles from structural plane data.
• Add a plunge: set the major direction within the local plane from a global azimuth and inclination, locally varying plunge data, or a plunge mesh.
• Dense data: with data such as blastholes, LocalVarioModels.fit_local fits local variogram volumes at each grid location.
• Gridded data: GridOrientEstimator estimates local orientations from smoothed gridded models that reveal geological trends.
• LVA variography: LVAExpVario selects composite pairs along local continuity directions, and get_h_pair_polylines shows how the pairs align.
• Local searches: rotate the LVA variogram at each grid node and extract local search ellipsoids so each node uses the most geologically relevant data.
