promptbind.utils.utils.uniform_random_rotation(x)

Apply a random rotation in 3D, with a distribution uniform over the sphere. :param x: vector or set of vectors with dimension (n, 3), where n is the

number of vectors

Returns:

Array of shape (n, 3) containing the randomly rotated vectors of x, about the mean coordinate of x.
