Volume rendering - Wikipedia
https://en.wikipedia.org/wiki/Volume_rendering- Volume rendering. For example, a volume may be viewed by extracting isosurfaces (surfaces of equal values) from the volume and rendering them as polygonal meshes or by rendering the volume directly as a block of data. The marching cubes algorithm is a common technique for extracting an isosurface from volume data.

That the engine used is called "volume rendering" is irrelevant to the article topic. The images must show the volume data throughout the volume. Otherwise one sees no difference from surface-based rendering. —Preceding unsigned comment added by 71.146.69.71 ( talk) 03:25, 4 May 2010 (UTC) [ reply]
