The triangular mesh is used to model petals and leaves, at the same time, the polygon is used to generate the flowers stamens and branches. 采用三角网格来构造花瓣和花叶的模型,采用多边形棱台构造花蕊和花枝模型。
For the first time, impact compactor with polygon roller for breaking up and compacting old cement concrete pavement slab in rehabilitating engineering of old cement concrete pavement. 通过非圆形轮冲击压实机械首次在修复旧水泥砼路面工程中用于打碎旧面板、稳固路基路面的工程实例,分析冲击压实机理及压实效果。
At the same time convert the angle of the polygon at that vertex into a straight angle. 哥特式穹顶的对角拱柱同时把该顶点处多角形的角转换成平角。
At the same time convert the angle of the polygon at that vertex into a straight angle. You just get improvements on the margin. 同时把该顶点处多角形的角转换成平角。你只能作点边边角角的改进。
At the same time the author points out that the polygon vertexes can be sorted clockwise or anticlockwise by judging the sign of the vector polygon area. 同时指出可以通过判断矢量多边形面积的正负值将多边形的顶点按照顺时针或逆时针方向排序。
