{:i8&4SSKrSSKrSSKJr "SS5rg)N)_apic\rSrSrSrSSjrSr\S5rSr Sr \ S 5r \ S 5r S r\S 5rS rSrg) Triangulationa An unstructured triangular grid consisting of npoints points and ntri triangles. The triangles can either be specified by the user or automatically generated using a Delaunay triangulation. Parameters ---------- x, y : (npoints,) array-like Coordinates of grid points. triangles : (ntri, 3) array-like of int, optional For each triangle, the indices of the three points that make up the triangle, ordered in an anticlockwise manner. If not specified, the Delaunay triangulation is calculated. mask : (ntri,) array-like of bool, optional Which triangles are masked out. Attributes ---------- triangles : (ntri, 3) array of int For each triangle, the indices of the three points that make up the triangle, ordered in an anticlockwise manner. If you want to take the *mask* into account, use `get_masked_triangles` instead. mask : (ntri, 3) array of bool or None Masked out triangles. is_delaunay : bool Whether the Triangulation is a calculated Delaunay triangulation (where *triangles* was not specified) or not. Notes ----- For a Triangulation to be valid it must not have duplicate points, triangles formed from colinear points, or overlapping triangles.
