geovista.filters

Filters to analyse, transform and process geolocated meshes.

These filters leverage and build upon the rich, powerful ecosystem of the Visualization Toolkit (VTK).

Notes

Added in version 0.1.0.

Functions

remesh(mesh, meridian[, boundary, check, rtol, atol])

Slice mesh along meridian and triangulate any sliced cells.

Attributes

REMESH_SEAM_EAST	Marker for remesh filter eastern cell boundary point.
VTK_BAD_TRIANGLE_MASK	vtkIntersectionPolyDataFilter bad triangle cell array name.
VTK_BOUNDARY_MASK	vtkIntersectionPolyDataFilter intersection point array name.
VTK_FREE_EDGE_MASK	vtkIntersectionPolyDataFilter free edge cell array name.

geovista.filters.remesh(mesh, meridian, boundary=False, check=False, rtol=None, atol=None)

Slice mesh along meridian and triangulate any sliced cells.

See the vtkIntersectionPolyDataFilter documentation for more.

Parameters:

meshPolyData

The surface to be remeshed.

meridianfloat

The meridian along which to remesh, in degrees longitude.

boundarybool, default=False

Whether to attach the remeshed boundary points mask to the resultant mesh.

checkbool, default=False

Whether to check the remeshed surface for bad cells and free edges.

rtolfloat, optional

The relative tolerance for longitudes close to the ‘wrap meridian’ - see geovista.common.wrap() for more.

atolfloat, optional

The absolute tolerance for longitudes close to the ‘wrap meridian’ - see geovista.common.wrap() for more.

Returns:

tuple of PolyData

The remeshed surface, the remeshed surface left/west of the slice, and the remeshed surface right/east of the slice.
