Existing polygon clipping algorithms are all offered for a rectangular window or a convex polygonal window.
已有的多边形裁剪算法都是针对矩形窗口或凸多边形窗口进行的。
A convex domain is approached by a convex polygon, and the approximated temperature distribution within the domain can be interpolated with the temperature data at the boundaries of the domain.
利用构造出的多边形有理插值，采用凸多边形逼近任意凸域，通过区域边界温度离散值，插值近似区域内的温度场分布。
Convex polygons are a usefulrepresentation, since we know that there are no obstructions between any twopoints inside a polygon.
凸多边形是一个很有用的表示法，因为我们知道凸多边形内部任意两点之间没有障碍。
