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.
