Hi folks!
This is my frist post and I'd like to know your opinion.
This gothic cloister is made object by object, i.e. stone by stone. The
columns are made of small cylinders with rounded corners, the walls with
small rounded boxes, etc. The roof is made also lime by lime. The only
bitmap texture used is the grass (with no big success, I guess).
I'm now programming (let me use this verb) a complete gothic cathedral using
the same procedure.
And now, let me arise one question: If you watch carefully and the image,
you can see that the boxes have a random ondulation. This is because they
are made with isosurface and the internal function f_rounded_box. I just
added some noise to the function. But the columns don't have this noise
because there is no functions to make a rounded cylinder. In my new
production (the Cathedral) I'm also using octogonal prisms and many other
complex 3D shapes, but they are made by unions of spheres (for the corners)
cylinders (for the vertices) and meshes (for the faces), so I can not assign
this random ondulation. Can you advise on any methodology to create complex
3D shapes using isosurface? A complex 3D shape for me is something like a
prism with irregular hexagonal base and a small curvature as it grows.
Cheers
Groucho-1024.

You prob already know this one but for many of us learning iso's this is
the Bible:
http://www.econym.demon.co.uk/isotut/index.htm
Can't tell you how to get a rounded iso "prism" to happen
but Mike has a lot there on sweeping shapes along splines. Maybe maybe.
I'm just not good enough with math hence iso's to say definitively.
Though I have thought of doing that myself
Beautiful picture so far!

Wow, really great job there !
I love the view, except the big column in the center :-\
So, the modelling is really fine. :-))

Yes, that column... I also don't like it very much.

This is very nice. I visited some gothic cloisters and this one looks
very real. I especially like the lighting.
One thing that distracts me a little bit is the tracery of the
"windows". It looks to thin for me. Was it made after a tracery in the
real word(tm)?
So long,
Bonsai

Use IsoCSG of http://www-public.tu-bs.de:8080/~y0013390/pov/ic/
Nice job, BTW.

Practically anything you make with CSG can be made with ISOCSG.

I didn't use any real model for this image. It just came to my mind.
Thanks for the comments. I'll use them for my new cathedral.
