The border panoramas are created by constraining viewpoint motion to arbitrary convexregion of a plane, and sampling cylindrical panoramas at border of the region point by point.
边界全景图通过限定视点在平面上任意的凸区域内运动，并且在区域的边界上逐点采样柱面全景图而构成。

We assume that the motion of controlled object is describedby linear ordinary differential equations with variable coefficient, and the final states ofthe system form a convexregion of phase space.
受控系统的运动设为变系数线性常微分方程组所描述，而系统的终点状态是相空间内的某一凸性区域。
