Hi All:

  Trying to recover from a long lack of inspiration, I started a
"remake" of my old scene "fuente". This was a kind scene that I always
wanted to try with radiosity. 

  I've not resited the temptation to do a "full rewrite" of the code
(still in progress). I used POV-Tree + TOMTREE for the nice palms
(thanks Gena & Tom!) and a modified Skylight.inc for the sky (thanks
Philippe!). 

  Critcism welcomed as usual!

Hi James,

I surely like the image. You're an expert in light and fine CSG modelling!

Personally, I would give the image more dynamic compression, to brighten the
building and the trees. Maybe the building is also a tad too blue and cold.
On a technical note, my first interpretion was that not enough sunlight
bounces off from the ground onto the walls, so all we have left is skylight.
After a closer look I realize it does bounce, as can be seen on the snip of
the building at the upper left.

But I would probably try increasing radiosity brightness and lowering the
skylight, or just adjust the white-balance. I would also use Kari Kivisalos
exposure control to avoid the sunlit area gets brighter than it already is.

The building seems as much in focus as the water fountain. The space
allocated for the building is rather big, and so the overall impression is
dark.

Regards,
Hugo

Hola Jaime,

I only have one remark : the shape of the falling water doesn't seem 
physically accurate, it doesn't have enough speed to get out 
horizontally like this, it should be falling much faster.

Apart from this little detail, this image is REALLY nice.
I can feel the freshness of the shadow in this very hot spanish afternoon.

Looks very good although the detail level of course is not suited for a
much larger render.  It is crying out loud for being rendered in HDR file
format though (so you can turn up the brightness and view the shadow parts
as well).  You could also render a nice light probe from it...

The palms are double_illuminate i assume?

BTW if you have a nicely working version of the skylight include file it
would be great if you could share it.  The one posted in p.b.s-f. seems to
be buggy in some ways and i have not yet found the patience to work though
all the suggestions for fixes etc. that have been posted in reply.

Can I do it with Pov 3.5 or do I need patch (and where to get it from)?

Use parabolic paths for water (with very small horizontal velocity). The
curent filleted-L flow is unnatural and distracting.

Nice image (as usual :)
I can just recommend how to imrove your palms. Maybe it's not
so bad for low resolution but mesh leaves will be too annoying in
high resolution.

The best result you can achieve using Tom Aust's heightfield
leaves (HF_PALMLEAF...) In this case you cannot save mesh
tree from POV-Tree but you can use TOMTREEm (included
with POV-Tree 1.2) to render the trees. It will reduce rendering
time. Also you will need leaf image map from original TOMTREE.

If you still prefer to use mesh leaves try to use the latest version
of POV-Tree 1.2. I fixed there a bug related to Mesh1 leaf. Now
it's triangular structure is not so visible because one side of the
triangle lays on branch.

For mesh leaves you could try also the following settings which
hopefully should help :)

Branch tab - Taper = 1.0
Bunch tab  - Taper Off At Tree = -0.3
Bunch tab  - Taper Off At Twig = -1.5

Gena.

Wow. This looks fantastic. I look forward to a more 
finished/larger/higher quality version. :D

One bit of advice I can think of: you might want to add some kind of 
texture to the palm leaves, as they look pretty bland right now and you 
can really see it in the foreground.

Ah, columns and arches. My favourites.

Beautiful image, but one thing bothers me: shouldn't the shape of the 
water squirts be more parabolic like, than the 
quater-circle-and-straight that it seems to be now?
