parq_blockmodel.geometry.LocalGeometry

class parq_blockmodel.geometry.LocalGeometry(corner, block_size, shape)

Local dense grid geometry with C-order indexing.

This class models the logical/local lattice only (local corner/origin, block size, shape). It has no rotation, CRS, or world-frame meaning.

corner

Local (u0, v0, w0) corner of the (i=0, j=0, k=0) block.

Type:

Point

block_size

Block dimensions (dx, dy, dz) along the local i/j/k (u/v/w) axes.

Type:

BlockSize

shape

Grid shape (ni, nj, nk) - number of blocks along each axis.

Type:

Shape3D

__init__(corner, block_size, shape)

Methods
