    \title Qt Quick 3D - Dynamic Model Creation Example
    \examplecategory {3D}
    \brief Demonstrates dynamic model creation.

    This example demonstrates creating models dynamically in an application. 10 models are created
    dynamically at the start of the application, and more can be added or removed using the
    \e {+} and \e {-} buttons.

    \section1 Setting Up

    \section2 Spawner Node

    We are going to need a \l Node to hold the dynamically created models.

    \snippet dynamiccreation/main.qml spawner node
    \dots

    \section2 Startup

    We're creating 10 models at \c Component.onCompleted so the example shows something at startup.

    \section2 Adding Models

    In order to add a new item to the scene, we first use the \l {Qt::createComponent}{Qt.createComponent}
    function to create a \l {Component} for our model. Then we use the component's
    \l {Component::createObject}{createObject} function to instantiate the item, passing in the
    position and scale as parameters.

    \section2 Removing Models

    Dynamically created models are removed simply by popping and destroying them from the instance
    stack.
