API更改

向类com.aspose.threed.Scene添加了新的静态方法:

    /**
     * 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;

这些重载允许直接从流构建场景，更多选项继承自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);

向类com.aspose.threed.Scene添加了新的静态方法:

    /**
     * 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;

这些重载允许直接从文件名构建场景，更多选项继承自scene.Open。

带有文件名参数的场景的旧构造器现在被标记为已过时，将来将被删除。

        //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");

向类aspose.threed.Node添加了新的静态方法:

    /**
     * Detach everything under the node and attach them to current node.
     * @param node 
     */
    public void merge(Node node);

这种新方法允许将所有内容从另一个节点合并到当前节点。

合并file1和file2的示例代码:

        var scene1 = Scene.fromFile("file1");
        var scene2 = Scene.fromFile("file2");
        scene1.getRootNode().merge(scene2.getRootNode());
        scene1.save("output.fbx", FileFormat.FBX7700_BINARY);
