Qt3D provides functionality for near-realtime simulation systems with support for 2D and 3D rendering in both Qt C++ and Qt Quick applications.

The functionality in Qt3D is divided into the following C++ modules:

Classes, types and functions are declared under the Qt3D namespace.

For Qt Quick applications, Qt3D provides the following QML modules:

Getting Started

For a C++ application that performs 2D or 3D rendering and also handles user input, add the following line to your qmake .pro file:

QT += 3dcore 3drenderer 3dinput

To include the definitions of the modules' classes, use the following directives:

#include <Qt3DCore>
#include <Qt3DRenderer>
#include <Qt3DInput>

A Qt Quick application requires also additional dependencies:

QT += 3dcore 3drenderer 3dinput qml quick 3dquick

Overview

The high level design and motivation for Qt3D is described in the Qt3D Overview. The Qt3D Renderer aspect offers support for data-driven configuration as described in Qt3D Renderer Framegraph.
