Nope, and me of course!!
I've now got a few bits on the webpage, so check out :

CITY PLANNERS,
I've got a 1 meter scale city.pov file and associated files, and am
awaiting o.k. from Michael. In the meantime, if anyone wants to play
with a 1 meter set of roads and plain, send me an email and I'll reply
with the zip file.
Regards,
Robert J Becraft

I just checked out your web page and it sez that one unit = one meter.
Hunh???????

The Y axis is UP? What country did YOU study geometry in? <G> This is
going to ruddy well make things difficult to produce in Moray, you know.
I'd like a plot in this little burg of yours, but I'm afraid that it'll
never work since I'll be using Moray.
jbm!

For as long as I can remember, POV-Ray has had the Y axis up and left handed
coordinates. Although that contradicts traditional mathematical 3-space, it
is the set used in many renderers and modelers. I don't know the reason for
sure, but i'm guess it's because most people are more comfortable with
two-dimensional cartesian coordinates with y being up and x being negative
on the left and positive on the right. If you've heard of the term
z-buffering, it's a technique for buffering 3-d information in relation to
the foreground and background. Anyway, If modeling with the y axis up is a
problem in moray, go ahead and model with the z axis up. When you're done,
export your scene to a pov file. Edit the pov file with a text editor and
wrap the whole thing in a union. Inside the closing brace of the union that
you added to the scene, add a rotation and it will spin your whole scene so
that the y-axis is up in your scene. It shouldn't hinder your modeling at
all. Good luck!

Yeah, it is....x is left-right, z is forward-back (into-outof), and y is
up-down....even maths geometry bears this out, on a 2d graph, x is
horizontal, y is vertical...if you add a third axis it Must be
forward/backwards.

Actually, traditional cartesian coordinates in 3-space have a vertical z
axis with x going in and out and y left to right.

I disagree. The Cartesian plane is 2D, x/y, traditionally considered to be
a flat horizontal surface (read "Flatland"), and we (the 3D folks) inhabit the
domains spread out along the Z axis. To look at it another way, X is
east-west, Y is north-south, and Z is in the atmosphere or underground. Don't
get all hornswoggled because your algebra teacher drew graphs on the
blackboard.
jbm!

Well, you know, that was my first thought. I'm a long time user and
strong supporter of MORAY. And although Y=UP is a bit alien to me
now too, it shouldn't be a problem. I intend to use MORAY (for
Windows) and just build everything so that Y is UP, even if MORAY
thinks Z is up. I could be wrong --- I havn't tried it yet --- but
it should work.
