def unstack_tangents(self):

Unstack over the tangent stack K: a K-shaped tree of tangents sharing this frame.

Decomposes the batch of tangent directions (“for each vector within the frame”). Each leaf is a T3Tangent with tangent_stack_shape == () and frame_stack_shape equal to this tangent’s – and, because the base point is shared across K, every leaf holds the same T3Frame object, so the leaves live in one tangent space (linear algebra between them is defined). Inverse of stack_tangents().
