parq_blockmodel.geometry.Geometry

class parq_blockmodel.geometry.Geometry[source]

Base class for geometry objects.

The geometry associated with omf block models are not defined by block centroids, and vary by block model type. In the pandas representation, the geometry is defined by the block centroids, so this class is used to define the geometry in terms of block centroids. Additionally, other properties of the geometry are defined here, such as the shape of the geometry.

Attributes (in omf and pyvista) are stored in Fortran ‘F’ order, meaning that the last index changes the fastest. Hence, the MultiIndex levels need to be sorted by ‘z’, ‘y’, ‘x’, to align with the Fortran order. This has x changing fastest, z changing slowest.
