详细说明

InstanceRepeater 类型用于基于Instancing 表创建多个对象。它是Repeater3D 的子类型，采用Instancing表而非数据模型，并自动应用position 、scale 和rotation 。

一种用例是通过创建与渲染实例匹配的不可见虚拟对象来实现picking 。为了提高性能，这些虚拟对象可以采用比实例化模型更简单的几何结构进行创建。

例如：

InstanceRepeater {
    instancingTable: myInstanceTable
    Model {
        source: "#Cube"
        pickable: true
        property int instanceIndex: index // expose the index, so we can identify the instance
        opacity: 0
    }
}
