## Detailed Description

The InstanceRepeater type is used to create a number of objects based on an Instancing table. It is a Repeater3D subtype that takes an Instancing table instead of a data model, and automatically applies `position`, `scale`, and `rotation`.

One use case is to implement picking by creating invisible dummy objects that match the rendered instances. To improve performance, the dummy objects can be created with a simpler geometry than the instanced models.

For example:

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

See also InstanceModel.
