Volume Rendering:

The short explanation:m trace the path of light. Show the final image based on that result.

Final product: a VOLUME mainly in Amira. Does not give specific region of interest.

The long and technically correct version: http://en.wikipedia.org/wiki/Volume_ray_casting

Whatever you visualize, is a VOLUME location. That means, no matter how you limit viewing area, your visualization is to any voxels with the same volume that possess the same gray scale value.


Allow highlight of individual structures. Does not visualize internal structures like volume renderings.
