PolyDataFilters.edge_mask(

angle: float,

*,

progress_bar: bool = False,

) → NDArray[np.bool_]

Return a mask of the points of a surface mesh with a surface angle greater than angle.

Parameters:

anglefloat

Angle to consider an edge.

progress_barbool, default: False

Plot the mask of points that exceed 45 degrees.

>>> import pyvista as pv
>>> mesh = pv.Cube().triangulate().subdivide(4)
>>> mask = mesh.edge_mask(45)
>>> mesh.plot(scalars=mask)
