A client-server view-dependent isosurfacing approach with support for local view changes

A new approach for view-dependent isosurfacing on volumetric data is described. The approach is designed for client-server environments where the client's computational capabilities are much more limited than those of the server and where the network between the two features bandwidth limits, for example 802.11b wireless. Regions of the dataset that contain no visible part of the isosurface are determined on the server, using an approximate isosurface silhouette and octree-driven processing. The visible regions of interest in the dataset are then transferred to the client for isosurfacing. The approach also enables fast generation of renderings when the viewpoint changes via minimal additional data transfer to the client. Experimental results for application of the approach to volumetric data are also presented here.
