公共API和向后不兼容的更改

请参阅对公共API所做的任何更改的列表，如添加、重命名、删除或不推荐使用的成员，以及对Aspose.3D for .NET所做的任何非向后兼容的更改。如果您对列出的任何更改有疑问，请在Aspose.3D支持论坛。

API更改

删除类Aspose.ThreeD.实用程序.元组

 In order to use some advanced features(CancellationToken), we have dropped the support of .net 3.5, so some replacement classes are also removed.

向类Aspose.ThreeD添加了属性AssetInfo。节点:

某些文件类型可以具有每个节点的资产信息。 在FBX中，根节点的AssetInfo属性包含FBX文件中定义的全局设置。

         /// <summary>

        /// Per-node asset info

        /// </summary>

        Aspose.ThreeD.AssetInfo AssetInfo{ get;set;}

示例代码:

         //Access GlobalSettings in FBX file, more properties can be found by opening the ASCII FBX files in a text editor.

        //And FBXHeaderExtension/SceneInfo inside FBX file will be mapped to Scene.AssetInfo

		Scene scene = new Scene(@"test.fbx");

        Console.WriteLine(scene.RootNode.AssetInfo.GetProperty("DefaultCamera"));

        Console.WriteLine(scene.RootNode.AssetInfo.GetProperty("UpAxis"));

        Console.WriteLine(scene.RootNode.AssetInfo.GetProperty("FrontAxis"));

在打开/保存方法中添加了取消令牌:

旧方法:

 		public void Open(System.IO.Stream stream, Aspose.ThreeD.FileFormat format)

        public void Open(System.IO.Stream stream, Aspose.ThreeD.Formats.LoadOptions options)

        public void Open(System.IO.Stream stream)

        public void Open(string fileName, Aspose.ThreeD.FileFormat format)

        public void Open(string fileName, Aspose.ThreeD.Formats.LoadOptions options)

        public void Open(string fileName)

        public void Save(System.IO.Stream stream, Aspose.ThreeD.FileFormat format)

        public void Save(System.IO.Stream stream, Aspose.ThreeD.Formats.SaveOptions options)

        public void Save(string fileName, Aspose.ThreeD.FileFormat format)

        public void Save(string fileName, Aspose.ThreeD.Formats.SaveOptions options)

新方法:

         public void Open(System.IO.Stream stream, Aspose.ThreeD.FileFormat format, System.Threading.CancellationToken cancellationToken = default(CancellationToken))

        public void Open(System.IO.Stream stream, Aspose.ThreeD.Formats.LoadOptions options, System.Threading.CancellationToken cancellationToken = default(CancellationToken))

        public void Open(System.IO.Stream stream, System.Threading.CancellationToken cancellationToken = default(CancellationToken))

        public void Open(string fileName, Aspose.ThreeD.FileFormat format, System.Threading.CancellationToken cancellationToken = default(CancellationToken))

        public void Open(string fileName, Aspose.ThreeD.Formats.LoadOptions options, System.Threading.CancellationToken cancellationToken = default(CancellationToken))

        public void Open(string fileName, System.Threading.CancellationToken cancellationToken = default(CancellationToken))

        public void Save(System.IO.Stream stream, Aspose.ThreeD.FileFormat format, System.Threading.CancellationToken cancellationToken = default(CancellationToken))

        public void Save(System.IO.Stream stream, Aspose.ThreeD.Formats.SaveOptions options, System.Threading.CancellationToken cancellationToken = default(CancellationToken))

        public void Save(string fileName, Aspose.ThreeD.FileFormat format, System.Threading.CancellationToken cancellationToken = default(CancellationToken))

        public void Save(string fileName, Aspose.ThreeD.Formats.SaveOptions options, System.Threading.CancellationToken cancellationToken = default(CancellationToken))

所有打开/保存方法都将有一个带有默认值的额外cancellationToken参数，因此使用这些方法的代码不需要修改即可编译。

您可以使用CancellationTokenSource在您需要的任何时间取消保存/打开任务。

示例代码:

         CancellationTokenSource cts = new CancellationTokenSource();

        Scene scene = new Scene();

        cts.CancelAfter(1000);

        try

        {

                scene.Open("test.fbx", cts.Token);

                Console.WriteLine("Import is done within 1000ms");

        }

        catch (ImportException e)

        {

                if (e.InnerException is OperationCanceledException)

                {

                        Console.WriteLine("It takes too long time to import, and we have canceled the importing.");

                }

        }
