A method and apparatus for efficient client - server visualization of multidimensional data

摘要

In response to a request from a client is a server for the volume is again administration, a volume data set from a memory archive, generates a sub-sampled copy low resolution of such a volume data set and transmits them to a client. In response to subsequent requests from the client, the server to the volume is again administration a image of high quality of the volume data set again and full resolution is a representation of a low quality of the sub-sampled copy of the volume data set, then generates a pixel mask or a hybrid pixel mask, which is characteristic for a difference between the image of high quality and the image of low quality, and sends such a mask of pixels to the client. The client receives from the server the pixel mask, and calculates an image of high quality based at least partially on the pixel mask and to a selective reproduction of its local sub-sampled copy of a lower resolution of the volume data set.
