How can I use Qt3D and traditional QML together?

[aktay]

Hi All,

I want to change the question. How can I edit the main.cpp file to use Qml3d and traditional qml together?

The main.cpp I'm using for this traditional qml

#include <QApplication>
#include <QQmlApplicationEngine>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QQmlApplicationEngine engine;
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

    return app.exec();
}

This is the main.cpp for qml3d

#include <Qt3DQuickExtras/qt3dquickwindow.h>
#include <Qt3DQuick/QQmlAspectEngine>
#include <QGuiApplication>
#include <QQmlEngine>
#include <QQmlContext>
#include <QQuickView>

int main(int argc, char* argv[])
{
    QGuiApplication app(argc, argv);
    Qt3DExtras::Quick::Qt3DQuickWindow view;

    view.engine()->qmlEngine()->rootContext()->setContextProperty("_window", &view);
    view.setSource(QUrl("qrc:/main.qml"));
    view.show();

    return app.exec();
}

Thanks.

Do you want to embed the images into the 3D scene, or do you need a 2D overlay on top of the 3D scene?

Hi,
I want use png and make image animation (rotate,propery animation etc..) I will also do 3D animation with them.

Okay. In this case, you need to render your image into a texture and apply the texture to a mesh.

Would you show me a simple example of how I should do it?

Thank you.

@aktay Sorry, I don't have the needed Qt3D skills for that :(

@Wieland Okay. Thank you for your help.
