New method for removing the staircasing effects of Shear -Warp

Shear -Warp algorithm is one of the most widely used Direct Volume Rendering (DVR) techniques. As the interpolation only includes one slice and overlooks the depth information, staircasing effects at some viewing angles may occurs. A new method is presented for removing the staircasing effects by introducing an adjustable factor. The factor only influences some elements of the warp matrix at some angles, which means a -little adjustment is added to the warp process while not increasing computation complexity. The comparison between the Sear-Warp method and the new one is included.
