Last January, I came across and intriguing photograph of Loubressac
Castle (Lot, France). It stayed in the back of my mind till this summer
when I started to model it in Silo, and thinking about a background
landscape. I remembered my own entry to one of the TC-RTC challenges
back in 2010 (Acres of Diamonds) and decided to use it. Many iterations
and transformations resulted in the present image.
Indebted to Mike Hazelgrove for the clouds macro; Gilles Tran for the
MakeGrass macro. Paolo, I tweaked your Grunge texture. Thanks indeed!
Some little tricks worth to mention: the Displacement utility in Poseray
was used for the tower so that the sunlight might be broken about the
masonry and the roof tiles. The trees, down in the plain, are
billboards. In order for the shadows to look right, they are composed of
two versions: one (with no_shadow) systematically oriented towards the
camera, one (with no_image) systematically oriented towards the Sun.

I really like the artistic composition of this image, and especially the chosen
late-afternoon (or early-morning?) Sun angle-- it throws the tower into shadow,
a nice touch. Beautiful,

That's quite clever, and works well! A nit-pic, though: It looks like the
'shadow billboards' are not quite lined up with the actual tree billboards; the
shadows are a little bit offset from the trees (to my eyes.) Not as to the
direction of the Sun, but as to emanating from the 'trees' themselves. The
shadow billboards had to be rotated to face the Sun, so maybe their
rotation-axes are not correct, i.e., offset somehow from the y-axis 'center' of
each billboard(?)

The shadow positions look fine to me. The problem I see is that there
is often no tree trunk shadow, probably due to them being narrower than
a pixel, and this makes the shadows seem disconnected from the trees.

Well gentlemen, this is interesting. Kenneth: I /think/ I have
positioned the billboard correctly according to origin, but I might need
to control this. Cousin Ricky: yes indeed, the trunks are a tad too
narrow. Maybe I should have planted different trees :-)

A very nice composition, and I like a lot the landscape and its colors.
The castle grass is kept very well by the gardeners (or maybe by the
goats), it is curious that there is so much moss on the stones...

fully agree with PG regarding landscape and colours. not too far off views seen
in the Eifel. lovely.

Well... I was wrong-- the shadows do line up. My apologies, Thomas! My eyes seem
to be working better today ;-) Yes, what threw me off were the missing (i.e.,
too thin) tree trunks in the tree shadows, and not seeing where the actual tree
trunks meet the ground.
Btw, the clouds in the image look really nice, a BIG detail I didn't pay
attention to at first... even though the title is "Pending Storm", ha. I was too
busy enjoying other parts of the image :-O

This is a nice image. Your buildings are excellent as always, but I'm most
intrigued by the landscape. The patchwork of fields is very convincing - you
allude to a previous challenge scene, but I'm sure I've never seen this effect
before. How was it done?
I've experimented briefly with British-style irregular drystone-walled fields
before, and it's no trivial problem! As with many experiments, it dissolved into
an abstract geometric modelling saga woefully unsuited to SDL, but I hope to
return to it someday...
Also excellent clouds!
Bill
