Yes, in more that one way. It is so much easier to make look, well, 
'interesting' than say a plastered or painted surface. And it makes it 
easy to get the dimensions right, you just count the bricks.

The credit goes to Kari Kivisalo who suggested the technique.

All vans look the same to me, but if we can trust the filename, it 
should be a Nissan Quest.

There really isn't much to reveal. As some has pointed out, patience is 
the main ingredient. I hardly use anything but the most basic CSG 
objects. I just use lots and lots of 'em.

  If you want examples, I posted the source for one of the buildings in 
p.b.s-f a while ago. Or you could take a look at the St Pauls dome, I 
posted for the Capriccio project recently. But I warn you: it is boring 
reading. :)

Thank you to you all for your kind comments.

One recurring "complaint" is that sky isn't realistic. To that I have 
this to say:

I like to model buildings, and I like to try to make them look 
interesting by modelling a lot of details, as opposed to doing fancy 
tricks with textures. I only use bitmap textures, if I can't avoid it 
(like the mosaics above the church doors).

The object of interest to me in this scene is the church. The sky, 
streets, trees, cars and the other building are merely set pieces, and 
it doesn't bother me much, if they look a bit artificial. After all, if 
I wanted a photorealistic image, I would have used my digital camera.

So there :)

Without a doubt a true "Rasmussen": highly detailed with this particular
model-like look. Congratulations for another incredible scene! As
others already pointed out, the sky does not really fit into the picture,
but I assume that it looks like you want it to, because you entitled
the picture as finished.

Marvelous work!

Well, i was more referring to the way you plan and do your work.  You seem
to declare elements that are used several times but don't use macros a
lot.  You also don't declare reoccurring measures but directly use
numbers.  Do you draw a lot of things on paper or do you have all measures
in mind?

Oh, you mean I should plan my work? I knew I was doing something wrong :)

Well, first I pick a building. It should be something that lends itself 
to my csg-only style of modelling. Brick buildings are good - Antonio 
Gaudi's buildings are not.


Then I take a lot of photos of it. From the photos I draw up a ground 
plan, to get the major dimensions down. With brick building this is 
mainly a matter of counting bricks. At this point I usually find that I 
don't have photos of all the details I need, so I take some more. (This 
normally repeats itself several times during a project. I have taken 
over 850 photos for the church scene.)

Once I have the overall dimensions, I may model a crude mock-up, just to 
check the proportions, but that was not necessary with the church, since 
the bricks gave me precise measurements over most of the building.

Now I divide the building up it some large parts, pick one and start 
modelling, more or less from the ground up. Each part is divided into 
smaller parts, which are again divided into smaller parts, down to a 
level, where it is suitable to model as a unit. Then the parts are 
assembled level for level, until assembling the whole building is a 
matter of sticking a dozen parts together. Everything is declared, 
modelled around origin, and moved to its place during assembly.

I do some loose sketching on paper, but mostly I use a CAD program.
I have done this long enough so I can model simpler stuff with the help 
of a few lines on a piece of paper, but more complex stuff, I construct 
in 2D in the CAD program, from which I can pull out the dimensions and 
coordinates I need for Pov.

Not much to it, really.

Pretty close, mine is a Nissan Serena. They look pretty much the same, as
far as I can see.. Hmm.. I'd like to get my hands on that model..

That would be difficult, as it is only a *virtual* model :->

All right, I know what you mean. I think, if you ask Gilles Tran nicely, 
he will give it to you, too.

I've had this problem with both bricks and lettering at a distance.
I've solved both problems by blurring the texture, using a macro that
blurs it according to the render resolution, camera angle, and distance.

I used the technique in my current IRTC entry, which has some signs in
the background; the signs get aliased too much without the technique.

John
