Qt5.12 C++ How to dynamically load QPIxmap as texture in QML 3DScene
问题
以下是您要翻译的内容：
有一个应用程序在2D（QGraphicScene）和3D（QML 3D场景）中显示地图。我们需要在3D场景上使用2D场景的QML代码动态显示地图。加载使用QQuickImageProvider进行，该方法在QML中的图像上成功运行，但TextureLoader无法识别。是否有更简单的方法，如果没有，如何解决这个问题？
id: scene3d
Entity {
Entity {
id: floor
components: [
PlaneMesh {
width: 10
height: 10
mirrored: true
},
TexturedMetalRoughMaterial {
id: material
baseColor: TextureLoader {
id: textureLoader
source: "image://colors/yellow.png"
format: Texture.SRGB8_Alpha8
generateMipMaps: true
请提供一个解决方案。

如果您使用QtQuick3D，可以通过将其设置为Texture.sourceItem来使用QtQuick 2D组件，例如：
Model {
source: "#Cube"
materials: [
DefaultMaterial {
diffuseMap: Texture {
sourceItem: Rectangle {
width: 256
height: 256
color: "#78a"
Image {
anchors.centerIn: parent
width: 224
height: 224
source: "https://stephenquan.github.io/images/qt/madewithqt.png"
}
}
}
}
]
}

英文:
If you use QtQuick3D you can use QtQuick 2D components such as Image by setting it to Texture.sourceItem, for instance:
Model {
source: "#Cube"
materials: [
DefaultMaterial {
diffuseMap: Texture {
sourceItem: Rectangle {
width: 256
height: 256
color: "#78a"
Image {
anchors.centerIn: parent
width: 224
height: 224
source: "https://stephenquan.github.io/images/qt/madewithqt.png"
}
}
}
}
]
}
