收缩环绕修改器

The Shrinkwrap Modifier allows an object to "shrink" to the surface of another object. It moves each vertex of the object being modified to the closest position on the surface of the given mesh (using one of the three methods available).

它可以应用到网格,格子,曲线,表面和文本。

选项

Nearest Surface Point.

目标
收缩目标,即用来收缩或包裹的网格。
偏移量
与计算后的目标位置所保持的距离,以BU(Blender Unit)为单位。
顶点组
顶点组,以控制每个顶点是否移动以及移动多少到其目标位置。如果一个顶点不是该组的成员,它不会产生位移(等同于权重0)。

模式

This selector specifies the method to be used to determine the nearest point on the target's surface for each vertex of the modified object. Some options will add some extra, specific controls to the panel.

最近的表面点

这将会选择相对于收缩目标而言最近的顶点。它会添加额外的选项 在表面上,用来保持计算出的顶点总是在它们的"地面"之上。它仅仅在 偏移量 不为空的时候才有意义。

投射

这将会沿着选择的轴投射顶点,直到它们碰到收缩的目标。不会碰到收缩目标的顶点将保持原来的位置。

Projection options.

Subdivision Surface Levels
This applies a (temporary) Catmull-Clark subdivision to the modified object, before computing the wrap when using Projection mode.
限制
This is a distance limit between original vertex and surface. If the distance is larger than this limit vertex would not be projected onto the surface,
Axis

修改的物体投射沿着所选择的局部轴。这些选项之间可以组合起来使用,以得到一个“中值轴”的投射。

X、Y、Z轴

Direction

This allows you to select the allowed direction(s) of the shrink along the selected axis. With more than one Shrinkwrap Modifier, negative and positive axes can be combined.

负向、正向

剔除面
This radio button allows you to prevent any projection over the "front side" (respectively the "back side") of the target's faces. The "side" of a face is determined by its normal (front being the side "from where" the normal "originates").
辅助目标
一个用来投射的额外的物体

最近的顶点

这将会吸附顶点到收缩目标上最近的顶点。它没带其他额外的选项。
