mymesh.delaunay.ConvexHull

mymesh.delaunay.ConvexHull(NodeCoords, method='scipy', OrientSurf=True)

Identify the convex hull of a set of points. For a 2D point set (np.shape(NodeCoords) = (n,2)), a 2D convex hull of line elements will be generated. For a 3D point set (np.shape(NodeCoords) = (n,2)), a 3D convex hull of triangle elements will be generated.

Parameters:

• NodeCoords (array_like) – Coordinates of points around which the convex hull will be identified. If shape = (n,2), a 2D convex hull will be identified, or if shape = (n,3) a 3D convex hull will be identified.

• method (str, optional) –

  Convex hull method, by default ‘scipy’.

  • ’scipy’ - Use scipy.spatial.ConvexHull

  • ’BowyerWatson’ - Generate a Delaunay triangulation by the Bowyer-Watson algorithm (BowyerWatson2d() or BowyerWatson3d())

  • ’GiftWrapping’ - Use the gift wrapping algorithm (GiftWrapping())

• OrientSurf (str, optional) – Ensure the normals of the convex hull are consistently oriented outward, by default True.

Returns:

Hull – Mesh object containing the convex hull. Hull.Type='line' for a 2D hull or Hull.Type='surf' for a 3D hull.

Return type:

mymesh.mesh
