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.

Thanks, again.  Now having rendered it, that's just what I'm looking 
for.  I'll need to play with the textures, thickness, etc. for my own 
purposes, but this is a great start.

Now that I rendered it, I see what you mean; I'll want all my grain 
going the same way, but, as you said, that's easy enough to adjust. 
Usually to get a good grain, I remember that it goes along the z-axis, 
and rotate no more than 10 degrees in the x-direction, and leave y 
alone.  But then, I'm a neophyte at wood; I mostly just use the 
"woods.inc" textures.

I tried your shingles. As other said, reduce the rotations, in shingles, 
the grain is mostly along the lenght of the pieces. ADD some tranlation 
to the pattern as all shingles come from different parts of the 
originals wood pieces.
My test with rotations under 5 degre and random displacements gives good 
results.
