- resqpy.olio.vector_utilities.points_in_triangle(points: ndarray, triangle: ndarray, points_xlen: int, triangle_num: int = 0) ndarray ¶
Calculates which points are within a triangle in 2D.
points (np.ndarray) – array of the points in 2D.
triangle (np.ndarray) – array of the triangle’s vertices in 2D, shape (3, 2).
points_xlen (int) – the number of unique x coordinates.
triangle_num (int) – the triangle number, default is 0.
triangle_points (np.ndarray) –
- 2D array containing only the points within the triangle,
with each row being the triangle number, points y index, and points x index.
