 ****** Gradient Magnitude Opacity Modulation: Enhances boundary in volume by multiplying gradient magnitude with voxel opacity
 ****** Illustrative Context Preserving Exploration: Automatic "open up" boundaries that are closer to viewer. Two parameters ICPE scale and ICPE smoothness controls "open up" depth and width.
-***** Dist. Color Blending: Enhancing depth info in volume rendering by darkening voxels far away from user/camera.

 '''Rendering panel:''' This panel is Dynamically generated panel when valid input is selected.
 * '''Techniques TAB ''' Under the techniques tab, there are currently five rendering methods available. Each of these are described below.
 ** Rendering Method
 *** '''VTK CPU Ray Casting:''' Uses the CPU for volume rendering, is parallelized and can take advantage of multi-core capabilities. Uses level-of-detail approach where low resolution is rendered while moving, and high resolution is rendered once motion ceases. Allows zbuffer compositing with texture map cross sections and non-transparent triangulated surface model.

 '''Important:''' when using Multi-Volume GPU Ray Casting, both bg and fg volume need to have '''same data type'''. Please use Cast Image filter to cast image with smaller data type to larger data type. For example, if bg volume is short and fg volume is float, use Cast Image filter to cast bg volume to be float. Using bg and fg volumes with different data type may cause Slicer to crash.
