I've finished buildings on the right side and
reduced saturation for all image maps.

If you are working on the scene please post your progress
in this thread so that we could know what we should do
next :)

We still need:
- more boats/sails
- textures for boats/sails
- more textures for cathedral
- clouds
- tiles for roofs (ideally macro)
- people in front of the cathedral (we could use image maps)

Hi Gena, I am still working to improve the detail and modelling of the 5 
figures I have done so far.

I'm still working on the triangle relief for the cathedral. It's
progressing extremely slow, as RL(tm) has been busy the past weeks. I've
dressed up a soldier with some equipment, so I can use the same figure
for all the poses.
Is there a deadline for the project?

No.
From one side it's good from the other it's not so good
when you don't have the deadline ;)

IMHO it looks much better now.
The very last suggestion to move moustache a bit
lower :)
If you don't mind I would try to work on the texture
whenever you are ready to post the source.

Keep on good job Jim :)

Would it be possible to post the real painting along with the POV image 
? As I remember it we should start to have quite an impressive ressemblance.

It's definitly a great team work !

We discussed this question already in one of the 'capriccio' threads.
Unfortunately we cannot do that because of copyright issues. You can
get the original here (click on image to enlarge it):

Also Christoph Hormann create some kind of private homepage. So all
contributors have access to it. We keep there high resolution version
of that painting and some other reference images. If you are want to
participate in the project just ask Christoph for login-password.

Thanks! We still have some vacancies open ;)

True.. I think I have to set my own deadline though.
I'll be on holiday in july without a Windoze pc to run poser on, and
when I return about August the 1. there's only a few weeks and I'm
having my final examination, then I'll move, and will only take my own
linux box with me..
I think I'll have to cut some cornes if I don't get a lot of my time
soon, but I'll release all the poser files/meshes/pov files so you can
improve it if it's needed.

I've created the macro for making tile roof.
Each tile is a mesh but it doesn't work as I expected.
Whenever I increase the number of tiles allocated
memory is increasing too. I'm just wondering
what's wrong? The source is in p.b.s.-f.

Changing the number of faces doesn't affect the memory use, so instanciation
works as it should.
I guess it's the texture statement as it's defined for each tile. Removing
all the individual statements cuts the memory use in half.
One possibility to solve this would be to use the cells pattern to cover the
entire mesh instead of texture each tile independently. Just scale the
pattern to match the tile size.
Great macro by the way, it should be very handy.

Thanks for hints Gilles!
I'll try to modify the macro.

I came upon the same problem some years ago but at this time the tiles were
made with CSG so making large roofs with them was out of the question due to
speed and RAM limitation... and texturing every tile didn't help!

> I'll try to modify the macro.

When I think of it, there could be a separate version of the macro that
would create the entire roof, or at least a half roof, as a single mesh. It
would take longer to parse, but the same roof (preferably saved as an *.inc
file) could be used over and over (like grass patches) which would be great
for some types of city pictures.

I modified the macro (source in p.b.s.-f.). Cells pattern is in use
and there is only one texture for the whole roof now. But the
memory still grows. I suspect something is wrong with declarations
just cannot realize what :)

That's a good idea about one mesh. I'll try to do that. Though
it's not so useful for current scene it can be useful for somebody
else in the future :)

Looks good (so does the 'version 18', i'm a bit late with my comments at
the moment...).  For rendering efficiency it would be better to put
several tiles (like a whole row) in one mesh.  This would cost more memory
but it would render faster.

I guess it's normal, as memory is allocated to each tile anyway, I suppose
for positionning and such (I'll let programmers tell you exactly what
happens). Increase the number of faces and you will see that the RAM use
doesn't change much for a given number of tiles, which proves that
instanciation works correctly.

Note that an additional benefit of using a single mesh is that you'll be
able to use the same mesh for both panes, thus cutting RAM use in half.

Txemi Jendrix is making boats for this scene and we need
textures for those boats, ideally for UV-mapping. As far
as I know he is using Hamapatch. What's the best way to
make such UV textures in this case?

Should he save model in OBJ format and using UVMapper
to make that UV template? What kind of template does
UVMapper produce? Is it rectangular image? Is there any
need in using warping software for making such texture?

Gena.

I think the wood textures of the boats should best be procedural, this
would require a good 'design' of the uv-coordinates so the grain of the
wood parts is oriented in a realistic way.

How can we produce those uv-coordinates? Through UVMapper (I've never
used it before)?

Gena.

BTW, can we use the cloth patch for POV-Ray for
making sails for some of those boats? Is it easier than
modeling it in Hamapatch?

I don't use Hamapatch, but UVMapper can do a pretty good job. For instance
the car here :
http://www.oyonale.com/iss/english/museum_07.htm
was uvmapped with it from a mesh that didn't any uv info at first.
I'm using the Pro version though, because the free one has too many
limitations for this sort of job.

About speed. It's very slow when it's used in CSG. Is there any way to
improve that? Should I use bounded_by? If so, where - tile, roof or
result of CSG?
