API changes

Added new static methods to class Aspose.ThreeD.Scene:

        /// <summary>
        /// Opens the scene from given stream using specified file format.
        /// </summary>
        /// <param name="stream">Input stream, user is responsible for closing the stream.</param>
        /// <param name="format">File format.</param>
        /// <param name="cancellationToken">Cancellation token to the load task</param>
        public static Scene FromStream(Stream stream, FileFormat format, CancellationToken cancellationToken = default(CancellationToken));
        /// <summary>
        /// Opens the scene from given stream using specified IO config.
        /// </summary>
        /// <param name="stream">Input stream, user is responsible for closing the stream.</param>
        /// <param name="options">More detailed configuration to open the stream.</param>
        /// <param name="cancellationToken">Cancellation token to the load task</param>
        public static Scene FromStream(Stream stream, LoadOptions options, CancellationToken cancellationToken = default(CancellationToken));
        /// <summary>
        ///  Opens the scene from given stream
        /// </summary>
        /// <param name="stream">Input stream, user is responsible for closing the stream.</param>
        /// <param name="cancellationToken">Cancellation token to the load task</param>
        public static Scene FromStream(Stream stream, CancellationToken cancellationToken = default(CancellationToken));

These overloads allow construct a scene directly from a stream, with more options inherited from Scene.Open.

        //Before 22.3, load a scene from stream:
        //var scene = new Scene();
        //scene.Open(stream);

        //Now we load a scene from stream
        var scene = Scene.FromStream(stream);

Added new static methods to class Aspose.ThreeD.Scene:

        /// <summary>
        /// Opens the scene from given path using specified file format.
        /// </summary>
        /// <param name="fileName">File name.</param>
        /// <param name="format">File format.</param>
        /// <param name="cancellationToken">Cancellation token to the load task</param>
        public static Scene FromFile(string fileName, FileFormat format, CancellationToken cancellationToken = default(CancellationToken));

        /// <summary>
        /// Opens the scene from given path using specified file format.
        /// </summary>
        /// <param name="fileName">File name.</param>
        /// <param name="options">More detailed configuration to open the stream.</param>
        /// <param name="cancellationToken">Cancellation token to the load task</param>
        public static Scene FromFile(string fileName, LoadOptions options, CancellationToken cancellationToken = default(CancellationToken));

        /// <summary>
        /// Opens the scene from given path
        /// </summary>
        /// <param name="fileName">File name.</param>
        /// <param name="cancellationToken">Cancellation token to the load task</param>
        public static Scene FromFile(string fileName, CancellationToken cancellationToken = default(CancellationToken));

These overloads allow construct a scene directly from file name, with more options inherited from Scene.Open.

The old constructor of Scene with a fileName paramter is now marked as obsoleted and will be removed in the future.

        //Before 22.3, load a scene from file:
        //var scene = new Scene();
        //scene.Open("fileName");

        //Now we load a scene from file
        var scene = Scene.FromFile("fileName");

Added new static methods to class Aspose.ThreeD.Node:

        /// <summary>
        /// Detach everything under the node and attach them to current node.
        /// </summary>
        /// <param name="node"></param>
        public void Merge(Aspose.ThreeD.Node node);

This new method allow merge everything from another node to current node.

Sample code to merge file1 and file2:

        var scene1 = Scene.FromFile("file1");
        var scene2 = Scene.FromFile("file2");
        scene1.RootNode.Merge(scene2.RootNode);
        scene1.Save("output.fbx", FileFormat.FBX7700Binary);
