<h3>[property:Integer count]</h3>
|
|
|
<p>
|
|
|
- The number of instances. The *count* value passed into the constructor represents the maximum number of
|
|
|
- instances of this mesh. You can change the number of instances at runtime to an integer value
|
|
|
- in the range [0, count].
|
|
|
+ 实例的数量。被传入到构造函数中的*count*表示mesh实例数量的最大值。
|
|
|
+ 你可以在运行时改变这个数值到 [0, count] 区间的一个整数。
|
|
|
</p>
|
|
|
<p>
|
|
|
- If you need more instances than the original count value, you have to create a new [name].
|
|
|
+ 如果你需要比原先的数量更多的实例数量，你需要创建一个新的[name]。

<h3>[property:BufferAttribute instanceMatrix]</h3>
|
|
|
<p>
|
|
|
- Represents the local transformation of all instances.
|
|
|
- You have to set its [page:BufferAttribute.needsUpdate needsUpdate] flag to true if you modify instanced data via [page:.setMatrixAt]().
|
|
|
+ 表示所有实例的本地变换。
|
|
|
+ 如果你要通过 [page:.setMatrixAt]() 来修改实例数据，你必须将它的 [page:BufferAttribute.needsUpdate needsUpdate] 标识为 true 。
