pytransform3d.rotations.matrix_from_two_vectors(a, b)[source]

Compute rotation matrix from two vectors.

We assume that the two given vectors form a plane so that we can compute a third, orthogonal vector with the cross product.

The x-axis will point in the same direction as a, the y-axis corresponds to the normalized vector rejection of b on a, and the z-axis is the cross product of the other basis vectors.

aarray-like, shape (3,)

First vector, must not be 0

barray-like, shape (3,)

Second vector, must not be 0 or parallel to a

Rarray, shape (3, 3)

Rotation matrix


If vectors are parallel or one of them is the zero vector
