    • A system and method for seamlessly combining client-only rendering techniques with server-only rendering techniques. The approach uses a composite stream containing three distinct streams. One stream is available to send geometry from the server to the client. Another stream contains video with transparent pixels that allow the client-rendered object to appear in the context of the server rendered objects. The third stream contains camera information. The invention can satisfy a number of viewing applications. For example, initially the most relevant geometry can stream to the client for high quality local rendering while the server delivers renderings of less relevant geometry at lower resolutions. After the most relevant geometry has been delivered to the client, the less important geometry can be optionally streamed to the client to increase the fidelity of the entire scene. In the limit, all of the geometry is transferred to the client and the situation corresponds to client-only rendering system where local graphics hardware is used to improve fidelity and reduce bandwidth. Alternatively, if a client does not have local three-dimensional graphics capability then the server can transmit only the video of the server-rendered object and drop the other two streams. In either case, the approach also permits for a progressive improvement in the server-rendered image whenever the scene becomes static. Bandwidth that was previously used to represent changing images is allocated to improving the fidelity of the server-rendered image whenever the scene becomes static.
    • 一种用于将仅客户端渲染技术与仅服务器渲染技术无缝组合的系统和方法。 该方法使用包含三个不同流的复合流。 一个流可用于从服务器向客户端发送几何。 另一个流包含具有透明像素的视频,允许客户端呈现的对象出现在服务器渲染对象的上下文中。 第三个流包含相机信息。 本发明可以满足多种观看应用。 例如,最初最相关的几何可以流式传输到客户端以进行高质量的本地呈现,而服务器以较低分辨率提供不相关几何的渲染。 在最相关的几何体已经传送到客户端之后,不太重要的几何可以选择性地流式传输给客户端,以增加整个场景的保真度。 在极限情况下,所有的几何都被传送到客户端,并且这种情况对应于仅客户机渲染系统,其中使用本地图形硬件来提高保真度并减少带宽。 或者,如果客户端不具有本地三维图形能力,则服务器可以仅传送服务器渲染对象的视频并丢弃其他两个流。 无论哪种情况,当场景变得静态时,该方法还允许在服务器呈现的图像中逐渐改进。 分配先前用于表示更改图像的带宽,以便在场景变为静态时提高服务器渲染图像的保真度。

    • Example apparatus, methods, and computers control establishing a shared parse scope between two computers that intend to be involved in a shared de-duplication action. One example method includes, upon determining that a first de-duplication logic and a second de-duplication logic are to participate in a shared de-duplication action for an object, controlling the first de-duplication logic to establish a shared parse scope with the second de-duplication logic. Establishing the shared parse scope may include negotiations between the computers, where the negotiations transfer dialect information. The dialect information may take the form of rules. The method may also include persisting the shared parse scope.
