For those with money to burn on custom flooring, the Voronoi transform of the rhombic Penrose tiling is lovely. From the Penrose tiling, you get that neat non-repeating pattern. From the Voronoi transform, you get something less likely to hurt your feet or get chipped-off corners.

I suggest quartzite or pearly white granite, with pink granite for the pentagons.

The pattern should also work nicely for driveways and showers, likely with different material. The feel in a shower should be almost as nice as hexagon tile, and it is possible to put perfect 5-way symmetry around a pentagonal drain hole.

That is a really cool idea! The whole Voronoi topic is kind of a passion project - I really like the look and feel of the Voronoi pattern.

So I'll keep that in mind for later, thanks!

Keep exploring it. Voronoi diagrams are woefully underappreciated. Your project looks to be the thing that is finally going to make me do a video card upgrade I've been procrastinating for years.

Very nice:

Cool idea, but I wonder about the feasibility. Do companies exist which can make these small tiles to such precise specification? And do they number them so you know where to place each one? How do you place the tiles so you don't get drift?

If you really want "small tiles to such precise specification", you can get stone cut with a waterjet... https://www.waterjetwonders.com/

...but that doesn't seem to be required. I guess it depends on how much you hate grout lines. My square 18" (45 cm) tiles have grout lines that are about 3/8" (1 cm) thick. There is plenty of wiggle room for inaccuracy. You could cut down big tiles with a chop saw.

If you want thin grout lines, or even none at all, you can pay for that. Using a waterjet might also save on wasted stone, which could matter if you use something costly like jade or lapis lazuli.

They wouldn't need to be numbered. There are not very many distinct shapes. It looks like a dozen, judging from those images somebody posted. (last 6 at the bottom of the page) Maybe you'd need numbering if you had the supplier cut unique edge tiles, but you could just cut those when installing.

awesome project and beautiful visual result!

minor semantic quibble: I don't understand the use of the term "real-time" for this project. Can you elaborate on which definition is your project using, and how it applies?

EllipticCurve4• 7 years ago

Thanks, that means a lot :)

In this case real-time in the sense that one can adjust parameters and (for not too many points) get an instant result instead of an image on disk. Additionally, I used all components to have it displayed with an adjustable fps count (OpenGL based rendering).

But I see, that the meaning of real-time is a bit biased. Any suggestions?

"Interactive"?
