Hi everyone,

I just posted a zip containing the include file in a message entitled 
"hexagonal patterns" over at p.b.scene-files.

Attached is an image showing the 11 basic patterns contained within that 
file. All patterns are pigment_pattern macros, and can be used in any 
material block. They are all gray-scale by default.

1) is a shortcut to "f_hex_h" in in functions.inc. I adjusted its 
properties so that the edges start at full black, and the center ends at 
full white (thanks to that handy float in the docs).

2) is like 1), but modified to exist in groups of three

3) is composed of randomly-colored hexagons

4) uses "hexagon" and 3) to place and optionally rotate a pigment in 
each hexagon

5) is like 4), but in groups of three, and without random rotation

6) is like a triangular version of "hexagon"

7) is like 6), but rotated 30 degrees and slightly larger

8) uses 4) and a spiral1 pattern to for a curved tessellation

9) takes a pigment and makes a kaleidoscope out of it

10) is a reference grid for using the ht(x,y) and ht2(x,y) macros

11) is like 3), but with triangles :)

And the last bit is a sphere_sweep demonstrating the use of the ht2(x,y) 
macro for placing points in trigonal space. Both the ht(x,y) and 
ht2(x,y) macros line up with the skewed grid represented in 10.

Note that numbers 4, 5, and 9 will take a custom pigment pattern. It's 
not so hard to make, say, a compound bug eye with number 4, using a 
cylindrical or spherical pigment as a base.

Full instructions and example files are included in the zip. I'll 
monitor both groups in case anyone has questions. Happy rendering!

Sam

Nifty Stuff, thanks! I'll probably spend a good part of the weekend playing with
them instead of unpacking and cleaning my new apartment - It's *SO* nice to have
someone else to blame for the irresponsible behavior that I was almost certainly
going to engage in anyway ;-)

Best Regards,
Mike C.

Thanks, Sam, for the hard work!  I'll definitely be playing around with this. I
also want to see if I can generate HF functions (and/or isosurface functions)
from the patterns; they would look quite nice as 3-D objects.

The possibilities seem endless!

Thanks Ken, and you're welcome :) You will have to scale the pattern if 
you plan on using it for a tiling height_field. The values "h1" and "h2" 
should work for this, though it may take a little adjustment.

I'm glad you like it!

Exactly Mike! :)

Thanks for the files, Sam. The patterns look great.

  How about submitting it to lib.povray.org?

It didn't seem like such a big thing to me, but thanks!
