Python quad_with_convex_quad Examples

Example #1

def test_QuadWithConvexQuad_non_intersecting():
    for i in range(10000):

        # Generate nonintersecting polygons
        subject, target = generate_non_intersecting(4, 4)

        # Do the clipping
        result = clip.quad_with_convex_quad(subject, target)

        # Ensure we no vertices
        assert len(result) == 0

Example #2

def test_QuadWithConvexQuad_intersecting():
    for i in range(10000):

        # Generate intersecting polygons
        subject, target = generate_intersecting(4, 4)

        # Do the clipping
        result = clip.quad_with_convex_quad(subject, target)

        # Ensure we have roughly valid number of vertices
        assert len(result) >= 3
        assert len(result) >= min([len(subject), len(target)])

Example #3

            # Do the clipping

            # Ensure we no vertices
            assert (len(result) == 0)

Example #4
