API changes

Added new static methods to class com.aspose.threed.Scene:

    /**
     * Opens the scene from given stream using specified file format.
     * @param stream Input stream, user is responsible for closing the stream.
     * @param format File format.
     * @param cancellationToken Cancellation token to the load task
     */
    public static Scene fromStream(Stream stream, FileFormat format, Cancellation cancellationToken) throws IOException;
    /**
     * Opens the scene from given stream using specified file format.
     * @param stream Input stream, user is responsible for closing the stream.
     * @param format File format.
     */
    public static Scene fromStream(Stream stream, FileFormat format) throws IOException;
    /**
     * Opens the scene from given stream using specified IO config.
     * @param stream Input stream, user is responsible for closing the stream.
     * @param options More detailed configuration to open the stream.
     * @param cancellationToken Cancellation token to the load task
     */
    public static Scene fromStream(Stream stream, LoadOptions options, Cancellation cancellationToken) throws IOException;
    /**
     * Opens the scene from given stream using specified IO config.
     * @param stream Input stream, user is responsible for closing the stream.
     * @param options More detailed configuration to open the stream.
     */
    public static Scene fromStream(Stream stream, LoadOptions options) throws IOException;
    /**
     * Opens the scene from given stream
     * @param stream Input stream, user is responsible for closing the stream.
     * @param cancellationToken Cancellation token to the load task
     */
    public static Scene fromStream(Stream stream, Cancellation cancellationToken) throws IOException;
    /**
     * Opens the scene from given stream
     * @param stream Input stream, user is responsible for closing the stream.
     */
    public static Scene fromStream(Stream stream) throws IOException;

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 com.aspose.threed.Scene:

    /**
     * Opens the scene from given path using specified file format.
     * @param fileName File name.
     * @param format File format.
     * @param cancellationToken Cancellation token to the load task
     */
    public static Scene fromFile(String fileName, FileFormat format, Cancellation cancellationToken) throws IOException;
    /**
     * Opens the scene from given path using specified file format.
     * @param fileName File name.
     * @param format File format.
     */
    public static Scene fromFile(String fileName, FileFormat format) throws IOException;

    /**
     * Opens the scene from given path using specified file format.
     * @param fileName File name.
     * @param options More detailed configuration to open the stream.
     * @param cancellationToken Cancellation token to the load task
     */
    public static Scene fromFile(String fileName, LoadOptions options, Cancellation cancellationToken) throws IOException;

    /**
     * Opens the scene from given path using specified file format.
     * @param fileName File name.
     * @param options More detailed configuration to open the stream.
     */
    public static Scene fromFile(String fileName, LoadOptions options) throws IOException;

    /**
     * Opens the scene from given path
     * @param fileName File name.
     * @param cancellationToken Cancellation token to the load task
     */
    public static Scene fromFile(String fileName, Cancellation cancellationToken) throws IOException;
    /**
     * Opens the scene from given path
     * @param fileName File name.
     */
    public static Scene fromFile(String fileName) throws IOException;

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:

    /**
     * Detach everything under the node and attach them to current node.
     * @param node 
     */
    public void merge(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.getRootNode().merge(scene2.getRootNode());
        scene1.save("output.fbx", FileFormat.FBX7700_BINARY);
