I believe this is called "FUTON bias" (https://en.wikipedia.org/wiki/FUTON_bias).

Some software I wrote got cited in a paper once. They had used it because it was readily available on the net. I didnt think anyone actually noticed.

Well crap there are pictures of it in a book too now.

What is the name of the software?

It was a simple voxel data viewer I wrote circa 1997? Called pkvox.

It could load, slice, and iso-surface up to about a gig of data with only 128meg of ram. I provided C++ source to write the file format.

Thanks for your contribution! I can't find it in the usual open archives. You might want to deposit the code on Zenodo, so it gets long-term preservation and a citable DOI. https://zenodo.org/

I'll look, but I'm not sure I even have the code any more. That was a long time ago. It had a software triangle rasterizer that pulled from a 3d voxel array to slice it. I always wanted to update it to store in 3d z-order so it would perform well on all 3 axis but never got around to it.

This seems to be the mentioned paper (program name was in https://news.ycombinator.com/item?id=23489882):

"Robust invisible watermarking of volume data using 3D DCT", doi:10.1109/CGI.2001.934699 , https://www.researchgate.net/publication/3904386_Robust_invi...
