    • Disclosed are a system and method for computing a desktop picture. Instead of loading a file that contains the desktop image from memory, the present invention provides for a system and method for opening and retaining a procedural recipe and a small set of instructions that can be executed to compute a desktop picture. The desktop picture can be computed very quickly using a GPU (graphics processing unit), and can be made to move on demand. When a part of the desktop image is needed to composite, that part is computed using a fragment program on the GPU using the procedural recipe and a specially written fragment program into a temporary VRAM buffer. After it is computed and composited, the buffer containing the result of the fragment program may be discarded.
    • 公开了一种用于计算桌面图片的系统和方法。 本发明不是从存储器加载包含桌面图像的文件,而是提供用于打开和保留程序配方的系统和方法以及可以执行以计算桌面图片的一小组指令。 可以使用GPU(图形处理单元)非常快速地计算桌面图像,并且可以根据需要进行移动。 当桌面图像的一部分需要复合时,该部分使用程序配方的GPU上的片段程序和特殊写入的片段程序计算到临时VRAM缓冲区中。 在计算和合成之后,可能会丢弃包含片段程序结果的缓冲区。
