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.

Surface:

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