mesh.Mesh.slice#

Mesh.slice(dir=0, n_planes=10)#

Intersect a triangular surface mesh with a series of parallel planes.

Parameters#

dir: int or array_like (3,): The direction of the normal on the planes. A single int (0..2) may be used to specify one of the global axes (0 = x-axis, 1 = y-axis, 2 = z-axis).
n_planesint: Number of slicing planes. The planes are positioned evenly between the minimum and maximum coordinates of the surface along the slicing direction, excluding the boundary values. Thus, n_planes planes partition the surface into n_planes + 1 sections of equal length. Must be >= 1.

list of Mesh: A list of n_planes meshes of type ‘line2’, representing the intersection of the triangular surface mesh with each plane.
