UT3Tangent.tangent_stack_shape

t3toolbox.uniform_manifold.UT3Tangent.tangent_stack_shape()

def tangent_stack_shape(self) -> typ.Tuple[int, ...]:

Tangent stack K: the extra outer batch of tangent vectors sharing this frame.

The part of the variation stack that exceeds the frame stack (often empty). The variation supercores are stacked (d,) + K + C + (core,) – extra axes outermost, frame stack inner.

Return type:

t3toolbox.backend.common.typ.Tuple[int, Ellipsis]
