Python scale_from_matrix Examples

Example #1

def test_scale_from_matrix():
    factor = random.random() * 10 - 5
    origin = np.random.random(3) - 0.5
    direct = np.random.random(3) - 0.5
    S0 = t.scale_matrix(factor, origin)
    factor, origin, direction = t.scale_from_matrix(S0)
    S1 = t.scale_matrix(factor, origin, direction)
    assert_equal(t.is_same_transform(S0, S1), True)
    S0 = t.scale_matrix(factor, origin, direct)
    factor, origin, direction = t.scale_from_matrix(S0)
    S1 = t.scale_matrix(factor, origin, direction)
    assert_equal(t.is_same_transform(S0, S1), True)

Example #2

def test_scale_from_matrix():
    factor = 7
    origin = np.array([0.2, 0.2, 0.2])  # arbitrary values
    direct = np.array([0.4, 0.4, 0.4])
    S0 = t.scale_matrix(factor, origin)
    factor, origin, direction = t.scale_from_matrix(S0)
    S1 = t.scale_matrix(factor, origin, direction)
    assert_equal(t.is_same_transform(S0, S1), True)
    S0 = t.scale_matrix(factor, origin, direct)
    factor, origin, direction = t.scale_from_matrix(S0)
    S1 = t.scale_matrix(factor, origin, direction)
    assert_equal(t.is_same_transform(S0, S1), True)
