Here's a more complete version of the frame.  The second picture shows 
the wind brace on the end, as Remy Closset mentioned.  There are still a 
few more changes to be made, such as, there really should be a smaller 
door on the front left, since the back is north, and the barn is 
supposed to be placed to the northeast of the house, given the 
prevailing westerly winds in the midwest USA.

Thanks for all the advice on woodgrain, shingles, etc.  More comments 
greatly appreciated.

(Talking to myself)

As I look at it, I'm sure that there should be trusses nearer to the 
ends -- it looks far too flimsy this way, although the plans didn't show 
this, and the details of tying in the faces clearly show that there are 
not supposed to be trusses at the very ends.

Oh, well.  It's easier to fix with POVRay than it would be in the other 
real life.

I love what you're doing.  I will be very interested to see how this
progresses.

I really like the fact that you're taking the time to make this "real".
Most of us would simply do the outside of the barn.  You're actually
building it piece by piece.  When you're done, you'll have a model that will
be perfect inside and out.  That's very commendable, imho.

Keep up the good work!

The cows are clapping (have you ever seen cows clap? It's quite a sight!).
Beeeoooooooootiful.
You have a lot of patience to put together something this detailed.

Thanks!  I made some improvements over the weekend, but not enough to 
warrant another post.  After looking at a neighbor's (smaller but 
similarly supported) barn, I decided that the trusses should be 12 feet 
apart, rather than 16, and start closer to the barn face, so now there 
are 7 trusses instead of 4, making it look much more substantial.  Also 
I noticed that the roof frame should extend 2 feet past the barn (for an 
overhang), and that the center "point" (I can't remember its name) 
should be only as wide as the haymow doors, and extend further out, to 
protect the pulley assembly (again I forget the name) used to get the 
hay into and out of the loft.

Anyway, I thought about trying to make just the outside, but my 
observational skills are so poor, that usually someone comes by and says 
"that barn (or whatever) couldn't even stand up the way you made it."

The nice thing about a barn is that, even when (if) it's completed, 
you'll still be able to see all of the construction details (from the 
inside).  It's also interesting to see how far you can get with just one 
primitive ("box.")  I'm not sure if it's practical to go any further 
with just boxes, since next come the lathes, and then the siding and 
shingles, and that's a lot of boxes.  I'm also toying with whether or 
not to include the internal ventillation, although the engineering 
aspects of that are really fascinating (how do you most efficiently 
remove methane from the barn and put it out into the atmosphere, where 
it belongs?)

Thanks for the interest and comments.

i must be rendering it incorrectly, it looked like chipboard

currently playing with a tutorial series wood_1..19.pov  (its on other 
box at moment, that i found semms to me, something is wrong with 
rand(R)*360 on all of x,y,z for the rotate
istr something in docs about 5-10 degrees about x or z axes's, the 
direction i think is really z (grain direction)
so i'm playing with different fading on some of the straighter grained 
wood textures.

Oops, I hadn't tried it yet, just read it, and it looked good.  Now I 
better try it and try to figure it out.
