pyvista.DataSet.find_cells_intersecting_line#

DataSet.find_cells_intersecting_line( pointa: VectorLike[float], pointb: VectorLike[float], tolerance: float = 0.0, ) → NumpyArray[int][source]#

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.
