公共边界 meaning in Chinese
shared boundary
Examples
- In coloring a geographical map it is customary to give different colors to any two countries that have a portion of their boundary in common
在给地图涂上颜色时,人们习惯于将两个具有公共边界的国家加上不同的颜色。 - During the division , edge locking and autocoding technique were developed to ensure the consistency of boundary and improve efficiency of coding work
在区划中,开发边界锁定技术保证了相邻区域区划结果公共边界的一致性;采用自动编码技术,提高了编码的工作效率。 - At last the smooth blending between adjacent nurbs surfaces are discussed , which includes the joining of two adjacent nurbs surfaces along the common boundary and the adjustment of more than two nurbs surfaces at corner , also the paper gives the concrete algorithm of surface blending
本文最后研究了nurbs曲面的光滑拼接。讨论了两相邻nurbs曲面沿公共边界的拼接和多片nurbs曲面在公共角点的协调及拼接技术,并给出了实用的优化拼接算法。 - An algorithm is proposed to avoid the crack between terrain blocks , set the state of the border vertices consistent forcibly , at the same time set the ancestors of these vertices active , which use the dag ( directed acyclic graphic ) to decide the dependency relationship of vertices
摘要提出了一种避免地形块间裂缝的算法,将公共边界上的顶点状态设为一致,对于那些由不活跃变为活跃的边界点,利用顶点引入次序的有向无环图将其祖先顶点也设为活跃。 - So as to deal with this problem , local b - spline surface designing method with complicated trimmed boundary constraints is advanced . for two neighboring surfaces , we first trim a belt along the common boundary and then bridge a b - spline surface between these two trimmed surfaces with a smooth blending . with respect to the comer area comprised of several adjoining surfaces , a rectangular region covering the comer area is obtained by trimming operations at first , and later a local b - spline for filling the rectangular region is completed through interpolation or approximation
在两张相邻的曲面之间,先在其公共边界处裁剪出一个带状区域,然后再采用曲面搭接的方式实现曲面之间的光滑过渡;而在邻接曲面的公共角点处,先在该角点附近区域裁剪出一个矩形拓扑域,然后运用插值或逼近的方法,设计出一张既满足于该区域的边界条件同时又插值或逼近内部采样点的b样条曲面。
