has a boundary \partial \mathcal{W}_{\gamma} with constant anisotropic curvature, where \gamma^{\circ}(p)=\sup\{p\cdot q;\gamma(q)\leq 1\} is the support function of \gamma . In fact, if the normal vector for the calculation of the curvature is oriented to the interior of \mathcal{W}_{\gamma} , then H_{\gamma}=1 on \partial \mathcal{W}_{\gamma} ; see [4] or [7] for details. We say H_{\gamma} is the crystalline curvature if \mathcal{W}_{\gamma} is a convex polygon. Since \gamma^{\circ} is positively homogeneous of degree 1, we here assume that \gamma^{\circ}(p) is a convex and piecewise linear function, i.e.,
