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, Qt Quick 3D provides 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's possible to mix Qt Quick 2D content with 3D content.
Using the Module▲
QML API▲
The QML types of the module are available through the QtQuick3D import. To use the types, add the following import statement to your .qml file:
import QtQuick3DThe following module imports provide additional functionality:
import QtQuick3D.Effects
import QtQuick3D.AssetUtils
import QtQuick3D.Helpers
import QtQuick3D.Particles3DC++ API▲
Using a Qt module's C++ API requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.
Building with CMake▲
Use the find_package() command to locate the needed module component in the Qt6 package:
find_package(Qt6 REQUIRED COMPONENTS Quick3D)
target_link_libraries(mytarget PRIVATE Qt6::Quick3D)For more details, see the Build with CMake overview.
Building with qmake▲
To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:
QT += quick3dBuilding From Source▲
When building from source, ensure that the modules and tools from the qtdeclarative and qtshadertools repositories are built first, as it's 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.
