Detailed Description
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
Classes, types, and functions are declared under the Qt3DRender namespace.
Overview
The Qt 3D Render aspect offers support for data-driven configuration as described in Qt 3D Render Framegraph.
