qt-多面体查看器不显示任何内容

Question

我是使用cgal的新手，我尝试了以下示例：

#include <QGuiApplication>
#include <QQmlApplicationEngine>

#include <CGAL/Exact_predicates_inexact_constructions_kernel.h>
#include <CGAL/Polyhedron_3.h>
#include <CGAL/IO/Polyhedron_iostream.h>
#include <CGAL/draw_polyhedron.h>
#include <fstream>


typedef CGAL::Exact_predicates_inexact_constructions_kernel  Kernel;
typedef CGAL::Polyhedron_3<Kernel>                       Polyhedron;
int main(int argc, char *argv[])
{

    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

    QGuiApplication app(argc, argv);

    Polyhedron P;
    std::ifstream in1((argc>1)?argv[1]:"data/bones.off");
    in1 >> P;
    CGAL::draw(P);
    return app.exec();
}

问题是它显示黑色查看器，我不知道这是什么问题

我在Fedora OS上使用qt-creator 有什么帮助吗？
