  abstract =   "Volume clipping is a useful aid for exploring volumetric
               datasets. To maximize the effectiveness of this technique,
               the clipping geometry should be flexibly specified and the
               resulting images should not contain artifacts due to the
               clipping techniques. We present an improvement to an
               existing  illumination model for volume clipping to allow
               sharp edges in the data to stay visible. These sharp edges
               often originate from material transitions in the volume or
               structures being partially cut by the clipping geometry. The
               focus is on high, industrial image quality and flexibility
               of the algorithm; techniques for using high-resolution
               polygonal meshes as clipping algorithms and removal of
               artifacts are presented. Features of the latest consumer
               graphics hardware are exploited to provide the visualization
               at an interactive framerate without the need for
               multipassing. We have validated the techniques presented
               here by implementing them in the context of a professional
               volume rendering application at Philips Medical Systems, and
               comparing our results with current results produced by
               existing solutions.",
