A little while ago there was a discussion of a maze pattern.
Well, the attached is a single CSG object, not a pattern, but it was
my first experiment with macros.
Worked out pretty well, but the parsing time is a tad high.
----------
Resolution 512 x 384
Time For Parse: 0 hours 22 minutes 57.0 seconds (1377 seconds)
Time For Trace: 0 hours 9 minutes 54.0 seconds (594 seconds)
Total Time: 0 hours 32 minutes 51.0 seconds (1971 seconds)
Official POV-Ray, on a Pentium III, 550 MHz, 128 Meg RAM
----------
Note that there is exactly one true path through the maze.
The macro takes parameters for number of rows and columns, and
a seed value for the random number generation.
Still need to work on:
- Splitting generation of data and creation of object, using a file to
store the data (to reduce parsing time between rendering attempts).
- Options for wall thickness and height, and for path width.
- Expanding my algorithm for a hexagonal shape (no promises!).
Any interest?

man... you are insane. in a good way though. can you make an addition that
will make something like a red path of dots that leads you down the correct
path?

Need you ask? Also, I would love to see this with some height, but I
doubt that you could get much of it in any sort of real scene. I don't
imagine that most renderings would use so many rows and columns so the save
data to file part might want to be an option.

And a 3-D example.
This one is a bit more reasonable on the parsing time,
since it is only 13x13.

I have posted another image that shows some height with a
slightly smaller maze.
My thought on the parsing time reduction was for possible uses of
a maze in an animation. The entire parsing time was for the
calculation of direction data. Since the direction data would not
change between renderings of scenes in an animation sequence,
it might be nice to just do those calculations once.
But you're right, most renderings probably don't need mazes that are
50x50 in size! Most of the details will be lost when viewed at an angle.

I can only make out about 2% of the text on that page. Any idea what
platform that program runs on ? I notice the file is compressed in
.LZH format which usually indicates it is not a Windows application.

It's called crumbs - breadcrumbs... you're in a maze with twisting
passages leading in all directions.

Yes.
Saving data to file is a good idea, especially for those fly over
animations.
There doesn't appear to be a way in, so I couldn't do the
puzel, as I didn't know where the start point and end point
was.

Its for Windows.
*.LZH seems to be quite popular in Japan. WinZip needs a plug in for it I
think, but Zip'n'all < http://www.zipnall.com/ > supports it directly and
is free.

Wasn't even aware of that one. It expects you to create the maze yourself.
Hmmm, perhaps a merging of the concepts...

Good work Robert. I had an idea of making the solution with a variation of
the recursion macro; differencing the solution from the walls to make one
path that went through. Problem would be that there might be other
solutions.. .oh well.
