拆分为实例

将选定的几何元素（如面）拆分为组，然后将每个组转换为一个实例。

输入

几何数据

标准的几何体输入。

选择

Boolean field indicating which geometry elements to include.

群组 ID

Integer field indicating which group each element belongs to. Elements with the same ID will be moved into the same output instance.

属性

域

要提取和拆分的几何类型。此处也是对 选中项 和 群组 ID 场进行评估的域。

点:

点、样条线控制点、顶点。

边:

网格边。

面:

网格面。

样条线:

曲线样条。

实例:

顶层级实例。已实现的实例将被忽略。

层:

蜡笔层。

Note

与所选域不匹配的几何体将被移除。例如，若选择 边，则输入几何体中的所有面、样条线和实例都将丢失。

输出

实例

包含了分组几何元素的实例。

群组 ID

每个实例的群组 ID．

示例

In the example above, we start with a grid of 1000x1000 square faces serving as "pixels." Then, we group these faces into patches by assigning them a group ID sampled from a Voronoi texture, and move each resulting instance by a random amount along the Z axis.

Note that, because the texture outputs floating point values between 0 and 1 while the group ID is an integer, all the values would be rounded to 0 or 1 and we would only get two groups. To get more variation, we multiply the texture value by 1000.
