PFragment

片段

Using this node, you can break particles into fragments, where each fragment may have a different shape from the original particle if you wish. An example would be fireworks, where an individual particle (perhaps a fireball) can be fragmented into many different shapes (in the case of fireworks, perhaps little stars).

使用这个节点，您可以将粒子分解为片段，如果您愿意，每个片段可能具有与原始粒子不同的形状。一个例子是焰火，一个单独的粒子(也许是一个火球)可以被分割成许多不同的形状(例如焰火，也许是小星星)。

Invisible selections

看不见的选择

The PFragment node will create invisible selections for the fragments and the remaining parts. These selections can be used to restrict materials. The following keywords apply. Note that these keywords are case-sensitive; you must use capital letters.

PFragment 节点将为片段和其余部分创建不可见的选择。这些选择可以用来限制材质。下面的关键字适用。注意，这些关键字是区分大小写的; 必须使用大写字母。

FEDGE

This selection is defined by the edges of the fragments.

这个选择是由片段的边界定义的。

FBACK

This selection consists of the reverse sides of the fragments.

这个选区包含了片段的反面。

FREDGE

This selection is defined by the edges of the remaining objects.

这个选择是由剩余对象的边界定义的。

FRBACK

This selection consists of the faces of the fragments. In Solid mode, these faces will become visible under the parting fragment. In Hollow mode, the selection consists of the remaining object’s inner surfaces.

这个选择包括片段的面。在固体模式下，这些面将成为可见的分离碎片。在 Hollow 模式下，选择包括剩余物体的内表面。
