在家用個人電腦或甚至可攜帶型裝置上，影像與影片的資料串流技術（例如JPEG/JPEG 2000和H.264）已相當成熟，然而，3D mesh streaming的技術在實用上仍有一定的距離，因此本研究提出一個以JPEG0 2000為基礎的mesh streaming方法，將其整合進一個普遍性的多媒體串流Server，使得這種mesh streaming的方法可以直接運用在現存的影像和影片串流技術之中。首先，將一個三維模型轉換為JPEG 2000的影像格式，接著以JPEG 2000所支援的串流技術為基礎，來達到在網路上以串流來傳輸三維模型資料的目的。
此外，以Motion JPEG 2000為壓縮基礎的影片，使本研究的方法不只可以傳輸一個靜態的三維模型，而且可以運用在一個三維的動畫之中，使多媒體串流可以僅用一個code stream來做傳送，為了增加本研究所提出mesh streaming這方法的實用性，因此將這種以影像為基礎的模型給嵌入X3D的場景之中，將這模型看成X3D所延伸的一個節點。由於此方法是以標準的影像壓縮技術JPEG 2000為基礎，所以本研究所提出的系統非常適合用在任何一個既存的多媒體串流系統。

For PC and even mobile device, video and image streaming technologies, such as H.264 and JPEG/JPEG 2000, are already mature. However, the streaming technology for 3D model or so-called mesh data is still far from practical use. Therefore, in this paper, we propose a mesh streaming method based on JPEG 2000 standard and integrate it into an existed multimedia streaming server, so that our mesh streaming method can directly benefit from current image and video streaming technologies. In this method, the mesh data of a 3D model is first converted into a JPEG 2000 image, and then based on the JPEG 2000 streaming technique, the mesh data can then be transmitted over the Internet as a mesh streaming.
Furthermore, we also extend this mesh streaming method for deforming meshes as the extension from a JPEG 2000 image to a Motion JPEG 2000 video, so that our mesh streaming method is not only for transmitting a static 3D model but also a 3D animation model. To increase the usability of our method, the mesh stream can also be inserted into a X3D scene as an extension node of X3D. Moreover, since this method is based on the JPEG 2000 standard, our system is much suitable to be integrated into any existed client-server or pear-to-pear multimedia streaming system.
