Qt Quick 3D

Qt Quick 3D 提供用于创建 3D 内容和 3D 用户界面的高级 API，基于 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 场景图形 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.

使用模块

QML API

The QML types of the module are available through the QtQuick3D 导入。要使用类型，添加以下 import 语句到 .qml 文件：

import QtQuick3D

The following module imports provide additional functionality:

import QtQuick3D.AssetUtils
import QtQuick3D.Helpers
import QtQuick3D.Particles3D

C++ 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 .

构建采用 CMake

使用 find_package() command to locate the needed module component in the Qt6 包：

find_package(Qt6 REQUIRED COMPONENTS Quick3D)
target_link_libraries(mytarget PRIVATE Qt6::Quick3D)

更多细节，见构建采用 CMake 概述。

采用 qmake 构建

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 += quick3d

构建从源

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 .

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.
