The Volume Rendering tab contains all of the controls pertaining to the 3D volume rendering. To turn the volume rendering on or off in the volume pane, click the Show Volume Rendering checkbox.

The Mode allows the selection of standard (Over Operator), or maximum intensity projection (MIP) rendering styles.

The Sampling frame controls the rendering quality. Increasing the value of the Final Rate improves rendering quality. The Interactive Sampling Rate controls the number of samples while translating, rotating, or zomming into the volume and when decreased allows for faster interaction.
