... non-periodically tiled plane.
Did you know that an infinite plane can be tiled in a way that it does
not repeat in any direction, despite following clear-cut rules?
One such tiling is the Penrose "P3" tiling shown in the attached image.
Fun fact: There are actually at least two different P3 tilings, but no
mortal could ever tell them apart - because any finite sub-section of
one can be found in the other as well.

Did you implement a penrose pattern ? a macro ?

Nice addition to the tiling patterns ... it'll make an excellent change
up to the ground plane I'd been using in my last couple of scenes. Danke!

another fun fact: raytracing is more fun than most video games (dang i'm
having fun with this pattern!)

All Povers are equal, but some Povers are more equal than others.
Hurray for RC4! :-)

Nice one.
It looks like smoothly polished hematite.

I suggest we go on strike. No more POV-Ray images here until we get RC4!
Hmmmm.... afraid that won't work.... ;-)

We oldies have not yet discovered tweeter ;-)
Especially the Justin Bieber one is going to be effective I am sure :-)
Aahh... how time flies! In my days I would have said Paul & Ringo need
RC4... :-)

POV-Ray releases are like new computers: As soon as you got it, you wish
you'd have waited a week or two to get That One Even Better Offer.
For instance, I don't think this will make it into RC4 (guess what it is...)

Isn't that the truth?

Internal sub-division of meshes?

With a grain of truth though, I'm sure ;-)

Yup.
So far it works for smooth meshes where each vertex has only one common
normal for all faces it is part of. (Or, more informally, for meshes
without intentional creases).
Handling creases will be somewhat more difficult, as it requires
triangle adjacency information at parse time.
Mesh boundaries pose yet another challenge.

I suppose it will be very useful for PovRay generated meshes. And could
be used with the Iso-approximation macros.

Hi, What's the texture you used for the tiles? could you post it?

I don't recall the exact settings. I'm pretty sure it used both a color
map and a bump map, both of which were certainly based on the "tiling
27" pattern.
