How to rotate 3d models rendered in Qt5.7?

[Poorti]

Hi All,

I am a newbie in Qt. Learning and exploring, I came across a sample application to load 3d models following the assimp-cpp sample in Qt5.7.
Previously, using the Qt5.6 version, I could load the model and could rotate it by (rt-mouse-click + drag) and move it by (left-mouse-click + drag).

However, I see that I am just able to move the model in 5.7 version.
How can I make it rotate as well.
Here is the snippet as in assimp-cpp,

int main(int ac, char **av)
{
    QApplication app(ac, av);
    Qt3DExtras::Qt3DWindow view;
    view.defaultFramegraph()->setClearColor(Qt::black);

    // Root entity
    Qt3DCore::QEntity *sceneRoot = new Qt3DCore::QEntity();

    // Scene Camera
    Qt3DRender::QCamera *camera = view.camera();
    camera->setProjectionType(Qt3DRender::QCameraLens::PerspectiveProjection);
    camera->setAspectRatio(view.width() / view.height());
    camera->setUpVector(QVector3D(0.0f, 1.0f, 0.0f));
    camera->setViewCenter(QVector3D(0.0f, 1.1f, 0.0f));
    camera->setPosition(QVector3D(0.0f, 2.5f, 2.0f));
    camera->setNearPlane(0.001f);
    camera->setFarPlane(100.0f);

    // For camera controls
    Qt3DExtras::QFirstPersonCameraController *camController = new Qt3DExtras::QFirstPersonCameraController(sceneRoot);
    camController->setCamera(camera);

    // Scene loader
    Qt3DCore::QEntity *sceneLoaderEntity = new Qt3DCore::QEntity(sceneRoot);
    Qt3DRender::QSceneLoader *sceneLoader = new Qt3DRender::QSceneLoader(sceneLoaderEntity);
    SceneWalker sceneWalker(sceneLoader);
    QObject::connect(sceneLoader, &Qt3DRender::QSceneLoader::statusChanged, &sceneWalker, &SceneWalker::onStatusChanged);
    sceneLoaderEntity->addComponent(sceneLoader);

    QStringList args = QCoreApplication::arguments();
    QUrl sourceFileName;
    if (args.count() <= 1) {
        QWidget *container = new QWidget();
        QFileDialog dialog;
        dialog.setFileMode(QFileDialog::AnyFile);
        sourceFileName = dialog.getOpenFileUrl(container, QStringLiteral("Open a scene file"));
    } else {
        sourceFileName = QUrl::fromLocalFile(args[1]);
    }

    if (sourceFileName.isEmpty())
        return 0;

    sceneLoader->setSource(sourceFileName);

    view.setRootEntity(sceneRoot);
    view.show();

    return app.exec();
}

Anything I can add here?

You will probably have to replace QFirstPersonCameraController by QOrbitCameraController.

That did the trick!!
Thanks a tonne!!!
