详细描述

The Qt 3D Render module provides an aspect, components, and other supporting types necessary to implement 2D and 3D rendering as part of the Qt 3D framework.

To use classes from this module, add this directive into the C++ files:

#include <Qt3DRender>

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

QT += 3drender
