Qt Quick 3D

Qt Quick 3D provides a high-level API for creating 3D content and 3D user interfaces based on Qt Quick. Rather than using an external engine which creates syncing issues, and additional layers of abstraction, we provide extensions to the existing Qt Quick Scene Graph for spatial content, and a renderer for that extended scene graph. When using the spatial scene graph it is also possible to mix Qt Quick 2D content with 3D content.

Prerequisites

The QML Types can be imported into your application using the following import statement in your .qml file:

import QtQuick3D

In addition to the base Qt Quick 3D Model, additional functionality is provided by the following module imports:

import QtQuick3D.Effects
import QtQuick3D.Helpers
import QtQuick3D.Particles3D

Building From Source

When building from source, ensure that the modules and tools from the qtdeclarative and qtshadertools repositories are built first, as it is not possible to use Qt Quick 3D without these. Having qtquicktimeline available is strongly recommended as well, since keyframe-based animations will not be available otherwise.

In addition, some of the examples rely on Qt Quick Controls.

Module Evolution

Changes to Qt Quick 3D lists important changes in the module API and functionality that were done for the Qt 6 series of Qt.
