Assimp::Exporter exporter;
for (int i = 0; i < exporter.GetExportFormatCount(); ++i) {
    cout << "第" << i << "种格式：" << endl;
    const aiExportFormatDesc* fmt_desc = exporter.GetExportFormatDescription(i);
    cout << fmt_desc->id << endl;
    cout << fmt_desc->fileExtension << endl;
    cout << fmt_desc->description << endl;
