eradiate.scenes.surface.triangulate_grid(x, y, z=None, flip=False, divide='nesw')

Create a 2D triangulation for a regular (x, y) grid.

Parameters:

• x (ndarray) – List of x grid values.

• y (ndarray) – List of y grid values.

• z (ndarray, optional) – If passed, a 3rd coordinate for vertices in gridded format (y-major).

• flip (bool) – If True, flip triangle orientation (clockwise by default).

• divide ({"nesw", "nwse"}, default: "nesw") – Cell division method.

Returns:

• vertices (ndarray) – Vertex list (y-major) as a (n, 2) array.

• faces (ndarray) – Face definitions as a (n, 3) array.
