Definition:Affine Frame/Definition 2

Definition
Let $\EE$ be an affine space with difference space $V$.

An affine frame may be given by the set of $n + 1$ points:
 * $\tuple {q_0, \ldots, q_n} = \tuple {p_0, p_0 + e_1, \ldots, p_0 + e_n}$

The frame $\tuple {p_0, e_1, \ldots, e_n}$ is then recovered by:
 * $\tuple {q_0, q_1 - q_0, \ldots, q_n - q_0}$
