我编写了一个简单的 Windows 窗体应用程序，它使用 ReconstructMe SDK，一个 3D 对象重建库。当我单击一个按钮时，程序会打开一个返回文件路径的文件选择器。然后，它应该加载 .obj 文件以打开现有的 3D 重建。但是，当我选择文件来创建表面时，它不会加载，并且会出现以下输出：

Error: ..\..\source\lib_reconstructme\src\surface\io.cpp(133): Throw in function void __cdecl LibReconstructMe::load_surface_osg(const class boost::filesystem::path &,class OpenMesh::TriMesh_ArrayKernelT<struct OpenMesh::DefaultTraits> &)
Dynamic exception type: class boost::exception_detail::clone_impl<class LibFundament::robvis_error>
std::exception::what: load_surface_osg not implemented
[struct LibFundament::tag_robvis_message *] = load_surface_osg not implemented

这是按钮的点击事件：

private: System::Void viewButton_Click(System::Object^  sender, System::EventArgs^  e) {
             std::string filename;
             if(openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK){
                filename = marshal_as< std::string >(openFileDialog1->FileName);
             }
             ReconstructionView(filename);
         }
}

这是我尝试加载文件的功能：

reme_error_t ReconstructionView(string fileName){
    // Create a new context
    reme_context_t context;
    reme_context_create(&context);
    reme_context_set_log_callback(context, reme_default_log_callback, 0);
    // Create and set new options
    reme_options_t option;
    reme_options_create(context, &option);
    // Bind the reconstruction options.
    reme_context_bind_reconstruction_options(context, option);
    // Increase resolution in all dimensions
    reme_options_set_int(context, option, "device_id", 2);
    // Compile for OpenCL device using the upper options
    reme_context_compile(context);
    // Create a new surface
    reme_surface_t surface;
    reme_surface_create(context, &surface);
    // Load surface from file
    if(!REME_SUCCESS(reme_surface_load_from_file(context, surface, fileName.c_str()))){ //error
        cout << "Failed to load file.\n";
        reme_surface_destroy(context, &surface);
        // Make sure to release all memory acquired
        reme_context_destroy(&context);
        return REME_ERROR_UNSPECIFIED;
    }
    // Visualize resulting surface
    reme_viewer_t viewer_surface;
    reme_viewer_create_surface(context, surface, ("ReconstructMe SDK: " + fileName).c_str(), &viewer_surface);
    reme_viewer_wait(context, viewer_surface);
    reme_surface_destroy(context, &surface);
    // Print pending errors
    reme_context_print_errors(context);
    // Make sure to release all memory acquired
    reme_context_destroy(&context);
    return REME_ERROR_SUCCESS;
}

即使我尝试加载不存在的文件，也会出现错误。例如，if(!REME_SUCCESS(reme_surface_load_from_file(context, surface, "example.obj")))即使文件不存在，此行也会生成相同的错误。我不知道问题出在文件选择器对话框的返回值上，还是出在导致错误的函数上。有人能帮我吗？
