# Definition:Affine Frame/Definition 2

An affine frame may be given by the set of $n+1$ points:
$\left({q_0,\ldots, q_n}\right) = \left({p_0, p_0 + e_1, \ldots, p_0 + e_n}\right)$
The frame $\left({p_0, e_1, \ldots, e_n}\right)$ is then recovered by:
$\left({q_0, q_1 - q_0 ,\ldots, q_n - q_0}\right)$
