<DIV>Hi,</DIV>
<DIV>I played with volume rendering, and I can remember this behaviour depends on the raycast function you use. You can use an other which will not blur your volume, but it will be very slow. In effect, the time needed to get a nice picture is the time needed to compute only one picture. When you rotate your volume you need to be able to compute about at least 10 pictures per second to get a nice animation. So in your case it may be very painful to rotate the object.</DIV>
<DIV>Hope it helps.<BR><BR><B><I>kalyan.pushpala@wipro.com</I></B> wrote:</DIV>
