The main changes are: - - - The `LavaVuModelViewer` class has been removed and the model visualisation has been ported to `pyvista` using a LoopStructural - wrapped `loopstructuralvisualisation`. Many of the functions have been re-named and can be combined with the `pyvista.Plotter` methods for advanced - visualisation. pyvista does not currently allow for interactive plots while using colab notebooks, so `jupyter_backend='static'` is needed. - - Datastructures for representing model input/output have been introduced including the `LoopStructural.datatypes.StructuredGrid`, - :class:`LoopStructural.datatypes.ValuePoints`, :class:`LoopStructural.datatypes.VectorPoints` and :class:`LoopStructural.datatypes.Surface`. These Datastructures - are intended to improve the accessibility of the modelling and allow for easier export into other software packages. - All data objects have a `.save` method that allows the user to save the points into various formats including `json`, `csv`, `vtk` and `geoh5`. - In the future exporters for gocad and other formats will be added. All objects also have a `.vtk()` method to return a `pyvista.PolyData` object. - - The solver options for the interpolators have been removed and only :meth:`scipy.sparse.linalg.cg` and :meth:`scipy.sparse.linalg.lsmr` are supported. - To use an external solver the `external_solver` argument can be provided to the `interpolator.solve` method, usually passed through - the `model.create_and_add*` methods. To specify specific arguments to the solver these can be passed through `solver_kwargs` dict. - - Improvements have been made to how unconformities are handled and their interaction with faults - - A framework for including inequalities into the interpolation has been added but there is no solver that can be used for solving this problem. - - A convenience class :class:`LoopStructural.LoopInterpolator` was added for building an implicit function without requiring the :class:`LoopStructural.GeologicalModel` - **Please report any bugs or issues on the github repository.** Overview ======== @@ -38,9 +20,115 @@ Loop is an open source 3D probabilistic geological and geophysical modelling pla initiated by Geoscience Australia and the OneGeology consortium.
