拆边修改器

The Edge Split Modifier splits edges within a mesh. The edges to split can be determined from the edge angle (i.e. angle between faces forming this edge), and/or edges marked as sharp.

Splitting an edge affects vertex normal generation at that edge, making the edge appear sharp. Hence, this modifier can be used to achieve the same effect as Auto Smooth, making edges appear sharp when their angle is above a certain threshold. It can also be used for manual control of the smoothing process, where the user defines which edges should appear smooth or sharp (see Mesh Smoothing for other ways to do this). If desired, both modes can be active at once.

The output of the Edge Split Modifier is available to export scripts, making it quite useful for creators of game content.

拆边修改器。

棱的角度

启用该选项时,如果棱的邻接面的二面角大于 分离角度 ,棱将会分离开。

分离角度
On 0: all edges are split. On 180: no edges are split.
棱角
启用该选项时,用 边特殊操作 ‣ 标记锐边 (编辑模式下的菜单快捷键: Ctrl-E )标记为锐边的棱将会分离。

Note

非流形 的棱(被多于两个的面共享的棱)会被分离。
