"Without the vivid colours generated by computer software, these transparent structures are instead defined by their topography, geometry and symmetry."
I don't think this means what she thinks it means...
this is clearly an image that has been generated by software...and not that well frankly...
No, I think she's right. (Unless you're trolling.)
The atomic structure is measured directly using AFM, or possibly STEM, and then the areas with the same feedback voltage are given the same colour by some software. This allows you to truly image atoms, or at least their electron cloud. That's how they did the famous IBM one.
but she's implying that these images are not CG but "instead defined by their topography, geometry and symmetry." - no matter how you define them, these structures can't be visualized without software - software that gives them this false colour.
@Gann: Gann has it. It's confusion over the term CG. Or an alternative analogy would be to call the false-color Hubble data "CG". I suppose a less misleading term would be 'computer-enhanced imagery'. CG by definition is produced entirely by a computer, meaning no external data (other than geometric equations) inform the result. If the colors and forms here represent scientific data, it ain't CG.
@worrytron: "CG by definition is produced entirely by a computer, meaning no external data"...um, this is wrong, sorry.
my point was intended to ask why this image, the product of software, looks so cheap...if you're using software to visualize data you can do a better job, no nickeling, higher bit colors etc...
@RenRen: Yeah sorry about that super glue. We were expecting some one else to look through it first. You may want to avoid the restrooms on the second floor for a while.
