Qt 3D c++ （四）：设置其他的必要参数

#include <QInputAspect>
#include <QPointLight>
#include <QFirstPersonCameraController>


main()
{
    Qt3DInput::QInputAspect *input = new Qt3DInput::QInputAspect;
    view->registerAspect(input);
    //QInputAspect负责创建物理设备并处理相关的作业,处理前端和后端节点之间的映射,负责根据当前输入设置建立要在特定时间运行的作业的对象。

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

    Qt3DExtras::QFirstPersonCameraController *camController = new Qt3DExtras::QFirstPersonCameraController(rootEntity);
    camController->setCamera(cameraEntity);
    //相机第一人称视角控制
}
