Python Rotation.from_matrix Examples

Example #1

File: test_rotation.py Project: vanthaiunghoa/kwiver

 def test_from_matrix(self):
     # Create a non-identity matrix from a different constructor that we
     #   assume works
     # Create new rotation with that matrix.
     # New rotation to_matrix method should produce the same matrix
     pre_r = Rotation.from_quaternion([+2, -1, -3, +0])
     mat = pre_r.matrix()
     r = Rotation.from_matrix(mat)
     numpy.testing.assert_allclose(mat, r.matrix(), 1e-15)

Example #2

 def test_from_matrix(self):
     # Create a non-identity matrix from a different constructor that we
     #   assume works
     # Create new rotation with that matrix.
     # New rotation to_matrix method should produce the same matrix
     pre_r = Rotation.from_quaternion([+2, -1, -3, +0])
     mat = pre_r.matrix()
     r = Rotation.from_matrix(mat)
