parq_blockmodel.geometry.WorldFrame

class parq_blockmodel.geometry.WorldFrame(origin=(0.0, 0.0, 0.0), axis_u=(1.0, 0.0, 0.0), axis_v=(0.0, 1.0, 0.0), axis_w=(0.0, 0.0, 1.0), srs=None)

World embedding for local geometry.

Holds world origin, orthonormal axes, and optional CRS. It is responsible for local<->world coordinate transforms.

origin

World origin coordinates (x0, y0, z0).

Type:

Point

axis_u

Unit vector for U-axis in world coordinates.

Type:

Vector

axis_v

Unit vector for V-axis in world coordinates.

Type:

Vector

axis_w

Unit vector for W-axis in world coordinates.

Type:

Vector

srs

Spatial reference system (CRS) identifier.

Type:

str, optional
