钩挂修改器

The Hook Modifier is used to deform a Mesh, Curve a Lattice using another object (usually an Empty or a Bone but it can be any object).

As the hook moves, it pulls vertices from the mesh with it. You can think of it as animated proportional editing.

在顶点运动方面,虽然牵引操作不能提供像形变键一样好的可控性,但是它有着可以直接抓取顶点操作的优势。

Hook Modifier.

物体
牵引顶点的物体的名字
顶点组

Allows you to define the influence per vertex.

Useful when you do not something other than a spherical field of influence.

半径
牵引作用的范围
强度

Adjust this hooks influence on the vertices, were (0.0 to 1.0) (no change to fully follows the hook).

由于多个牵引操作可作用在同一个顶点上,你可以用这个属性来加权一个牵引操作的影响力。

衰减类型
This can be used to adjust the kind of curve that the hook has on the mesh. You can also define a custom curve to get a much higher level of control.
均匀衰减

当你在缩放过的物体上用牵引修改器时,该项设置有用,尤其是在非均匀缩放会拉伸牵引修改器作用的结果的场合中。

This is especially useful for lattices, where its common to use non-uniform scaling.

以下设置仅在编辑模式可用:

重置
重新计算,并清除牵引操作的偏移变换
重定位中心
设置牵引中心为3D光标的位置。
选择
选择受该牵引操作影响的顶点
指派
指定选择好的顶点到该牵引修改器。

Note

The Hook Modifier stores vertex indices from the original mesh to determine what to affect; this means that modifiers that generate geometry, like a Subdivision Surface Modifier, should always be applied after the Hook Modifier; otherwise the generated geometry will be left out of the hook's influence.
