inlinestatic

Returns element i ( \( 0 \le i < 3 \)) of the rotated 3-vector \( e_1 \cdot e_2 \cdot e_1^{-1} \).

Template Parameters

E1	The quaternion expression type.
E2	The vector expression type.

Parameters

e1	The quaternion expression (rotation).
e2	The 3-vector expression to rotate.
i	The zero-based element index (0, 1, or 2).

Returns

The rotated vector's i-th element (zero for i > 2).

Exceptions

Base::SizeError

if e2 has fewer than 3 elements.
