Hello,

I don't know if this is the right place to post my question. If I'm mistaken,
please let me know where to post it.

I'm trying to create arches like the ones given in the following photo :
https://commons.wikimedia.org/wiki/File:Mosque_of_Cordoba.jpg but I didn't
succeed.

Could someone help me please in creating the pov script. I also would like to
know how can we map alternating colors (white and red) like the ones in the
photo.

Thanks in advance

Walid

Simple questions like this probably should be in the new user group.
But as to your problem, POV's CSG should do the trick.

3.4.5.4 Constructive Solid Geometry in the documention should help.

I really hate to tell you more. Part of the fun I have with POV when I first
started was trying to figure these things out. Once you learn something you can
add to it to make somethings else. Of course a few hints along the way can't
hurt!

Look at 3.4.7.1.22 Radial Pattern for ideas of how to get the colors you need.

Have Fun!

An old timer. :-)
Hints rather than solutions at first. :-)
But if that doesn't help ask again. We don't want to publish spoilers. 
In case we spoil your fun.


There are macros that will give you macros to give different types of 
arches. It just takes good google-fu to find them. IIRC Thomas wrote one 
for a cobblestone street. In a horizontal arch configuration.

I wrote the cobblestone macro (in the Objects Collection) but failed on 
the arched version. My call for help went not unanswered: Chris B 
uploaded a macro set (CurvedPaving) to the Collection in 2008.

Take the hints from the others, and concentrate on oly a single arch.
When you get that single arch right, use a #declare to give it a name, 
then you will be able to use loops to make as many copies as you need in 
your project.
