# Qt 3D Extras C++ Classes

The Qt 3D Extras module provides a set of prebuilt elements to help you get started with Qt 3D. More...

This module is deprecated since 6.8. We strongly advise against using it in new code.

## Detailed Description

This module is still in development but is available as a technology preview. This means it is unstable, likely to change and provided as a convenience only.

     #include <Qt3DExtras>

To link against the corresponding C++ library, add the following to your qmake project file:

     QT += 3dextras

Classes, types, and functions are declared under the Qt3DExtras namespace.
