I made a macro that builds a brick arch over a given distance. You can set
several parameters to control the type and appearance of the arch. Have a
look at
http://www.b0n541.net/povray/povmacro.html
for further information.
Comment are welcome...
So long,
Bonsai

Nice, i have a couple of suggestions:
- Use optionally non-parallel bricks (so the mortar is not broader at the
outside)
- Allow also other objects like rounded boxes, isosurfaces, etc.
- Have some random variation of the single bricks
- allow longer arches with multiple bricks along the length

Already planned. I have also some other features in mind.

Maybe after I did the non-parallel bricks.

You can define the texture of the bricks and the mortar as a parameter. It
is not seen very well on the example picture I've posted because of the jpg
compression and the small image size. I also tried to define some randomness
with the rand()-function but with no success until now.
> - allow longer arches with multiple bricks along the length
You can define the length of the arch with the first parameter. I don't know
if the English word "span" is a right translation of the German word
"Spannweite" in the field of architecture. Maybe there is a better
translation. An other parameter that has an effect on the number of bricks
is the brick height. If you mean that it would be useful to have more rows
of bricks to make the arch thicker this is also a planned feature.
Thanks for the comments,
Bonsai

Just an idea, how about the option to make it output just an array
with coordinates, so the user can put any desired object in the stones
position?

The positions depend on the size of the objects. So I have to know at least
the length and height of the object to calculate the number of objects
needed. I can give the object itself as an parameter to the macro like I do
it with the textures. Would this also meet your suggestion?

With length i meant what you named 'thickness of the arch' i.e. the length
of the arch along the axis of the cylinder it is following. A very 'long'
arch would be more of a tube.

I'd call that the depth. Not to be confused with height and not to be
confused with radius.

Yes span is correct.
