pyvista.DataSet.find_cells_intersecting_line

DataSet.find_cells_intersecting_line(

pointa: VectorLike[float],

pointb: VectorLike[float],

tolerance: float = 0.0,

) → NumpyArray[int]

Find the index of cells that intersect a line.

Line is defined from pointa to pointb. This method requires vtk version >=9.2.0.

Parameters:

pointasequence[float]

Length 3 coordinate of the start of the line.

pointbsequence[float]

Length 3 coordinate of the end of the line.

tolerancefloat, default: 0.0

The absolute tolerance to use to find cells along line.

Returns:

numpy.ndarray

Index or indices of the cell(s) that intersect the line.
