QT中加载3D飞机模型的3D代码

以下是在QT中加载3D飞机模型的示例代码：

#include <Qt3DExtras/Qt3DWindow>
#include <Qt3DExtras/QOrbitCameraController>
#include <Qt3DExtras/QPhongMaterial>
#include <Qt3DExtras/QGoochMaterial>
#include <Qt3DExtras/QCuboidMesh>
#include <Qt3DCore/QEntity>
#include <Qt3DRender/QCamera>
#include <Qt3DRender/QPointLight>
#include <Qt3DRender/QMesh>

int main(int argc, char *argv[])
{
    QGuiApplication app(argc, argv);
    Qt3DExtras::Qt3DWindow view;
    view.defaultFrameGraph()->setClearColor(QColor(QRgb(0x4d4d4f)));
    QWidget *container = QWidget::createWindowContainer(&view);
    QSize screenSize = view.screen()->size();
    container->setMinimumSize(QSize(200, 100));
    container->setMaximumSize(screenSize);

    Qt3DCore::QEntity *rootEntity = new Qt3DCore::QEntity;
    Qt3DRender::QCamera *cameraEntity = view.camera();

    cameraEntity->setProjectionType(Qt3DRender::QCameraLens::PerspectiveProjection);
    cameraEntity->setPosition(QVector3D(0, 0, 40));
    cameraEntity->setViewCenter(QVector3D(0, 0, 0));

    Qt3DCore::QEntity *lightEntity = new Qt3DCore::QEntity(rootEntity);
    Qt3DRender::QPointLight *light = new Qt3DRender::QPointLight(lightEntity);
    light->setColor("white");
    light->setIntensity(1);
    lightEntity->addComponent(light);
    Qt3DCore::Transform *lightTransform = new Qt3DCore::QTransform(lightEntity);
    lightTransform->setTranslation(cameraEntity->position());
    lightEntity->addComponent(lightTransform);

    Qt3DCore::QEntity *modelEntity = new Qt3DCore::QEntity(rootEntity);
    Qt3DRender::QMesh *modelMesh = new Qt3DRender::QMesh;
    modelMesh->setSource(QUrl::fromLocalFile("path/to/your/airplane.obj"));
    Qt3DExtras::QPhongMaterial *modelMaterial = new Qt3DExtras::QPhongMaterial;
    modelMaterial->setDiffuse(QColor(QRgb(0xbeb32b)));
    modelMaterial->setShininess(100);
    modelEntity->addComponent(modelMesh);
    modelEntity->addComponent(modelMaterial);

    view.setRootEntity(rootEntity);
    container->show();

    Qt3DExtras::QOrbitCameraController *camController = new Qt3DExtras::QOrbitCameraController(rootEntity);
    camController->setCamera(cameraEntity);

    return app.exec();
}

请将代码中的 `path/to/your/airplane.obj` 替换为您的3D飞机模型文件的路径。此代码使用了Qt3D模块来加载3D模型，并在场景中添加了光源和相机控制器。
