| World record in 3-D imaging of porous rocks: Stack of 35 million megapixel-photos Posted: 19 Oct 2011 07:55 AM PDT Physicists have established a world record in the field of three-dimensional imaging of porous materials. The scientists have generated the largest and most precise three-dimensional image of the pore structure of sandstone. The image was generated within a project of the Simulation Technology Cluster of Excellence, and contains more than 35 trillion (a number with thirteen digits) voxels.  |
