Hello, folks.

I've just gotten around to creating a scene that I kind of like.  It
started off as an idea inspired by Greg's train-tracks, where I wanted
loads of roads all over the place, and I stumbled across some
algorithms for creating mazes.  I naively Googled  for "maze
algorithm" and was soon myred in Kruskals, Aldus-Broders, the
difference between Bias, Run and River, and other strangeness, and
realised this could go too far!
So I stuck to the first algorithm I found, and build some macros for
POVing it up into an image...

Now I want to add some more poses for my escaping stickmen, and for
some reason I've made their torsos the same colour as the walls, so
they blend in a bit too well...  As you can see my lighting and
textures a bit simplistic, but I might leave them as they are for now.

If anyone's curious about the maze maker, take a peek at my old
website www.sunmaster.pwp.blueyonder.co.uk/povray (how's that for a
domain name!) where it can be seen in all it's glory.  All the mazes


And if ANYONE suggests I animate the people running around and
escaping, I will throw all my toys out of my pram and scream.  It's
not going to happen.

(btw, thats ~20,000 objects for a 25x25 maze)

Nice.  Find any alorithms for "hexagonal" mazes?

Hmmm.  Seems a bit high.

Have you thought about using a hight field for the maze walls?  Then you
could reduce the amount of objects and probably speed up the rendering.
This is the technique Gilles Tran uses for his building faces.  You'd just
have to output an a bitmap instead, or do it with the new functions, which I
haven't tried yet.

This is waht I like about POV - it ain't just a renderer - its a whole
visualisation tool.

PS. I'd like to see them runn ...

Innit just

I've been trying, I have been working on getting my people moving, and
running/walking/standing/etc are possible, but the transition from a
walk to a run to a stand...

Generally, I've been having more trouble creating a maze-solving algo
than I did making a maze-building one.  I'm not sure if that's a
time-of-day problem or a total-lack-of-inspiration problem, but we'll
see.

Any help/clues greatfully received, (source on the website, and I'll
post in p.b.s-f if enough interest - as if)
