So that's what it looks like! :) Thanks a bunch!

Ain't you a tricky one ;) Tak!

If the final resolution are to be 6000x8000 the triangle will then be
about 1050pixels wide, or? I just need a feeling of how detailed it has
to be.

I've attatched my first test render, and looking at the new reference
pictures I think I can get away with it if I do some helmets in Wings.
And perhaps a sword, and some nice outfits and armor and.. :) Hmm.. The
casual Poser 3 man might look better because he has a t-shirt on.. This
is fun! *running away playing more*

I get the triangle to be close to 25% of the image width, at its widest, 
which is 1500 pixel. I don't have the exact size of the triangle, as it 
is going to be the last part, that I model, unfortunately, due to the 
way I'm working through the building. The acute angles a going to be 
close to 27 deg, though.

Looking very promising.

Gena, exactly how did you generate that second image?

Never mind, I see now.

Just a clarification for the other people :) The texture should look
smth. like:

pigment {
    gradient -z
    color_map {
        [0 1 color rgb 0 color rgb 1]
    }
    scale ...
    translate ...
}
finish{ambient 1}

The main problem is  that scale... translate ... block. You have either
to know minimum and maximum Z coordinate of your object or just
play with it.

Ok, I'll do some dummy boxes to test with.
Here is another test with the reference picture embedded for comparsion.
Is there need for much more detail? I need to postion the bodies so that
they give more depth. And by the way, you can't open the mouth of the
horse in Poser 3.

If anyone is interested, I did it like this:
Posed a horse and a casual male in Poser.
Exportet to obj, then to pov via PoseRay, fixed the textures.
Used a texture similar to Gena's and rendered a orthographic view or the
model which I saved in resolution 1000x1000 (png).
When I had two such greyscale maps, I used them as height_fields and
positioned them together with the temporary csg sun, then I did another
orthographic shot and saved the last heightfield.

But now a question, what is the man to the far left doing? ("O" marks
him ;-)
Is he bending his hip in some insane position, or is there two people on
the horse? Is he strangeling himself or covering his eyes?

Perhaps I'm too tired..

And if, like me, you happen to be using a mesh2 object that you converted
using 3dwin, you must remember to remove the uv_mapping keyword from the
object declaration. ;)

Gena, I know I read somewhere that you published a somehow faster 
version of Tomtree or something to that effect.  But I can no longer 
find where you referred to it or where it is.  Could you remind me where 
you put it?

Thanks, Jim

PS. your -z gradient pigment thingy has given me an idea for the next 
IRTC round.

See the post in p.b.s.-f. group with subject 'Tree + Snow' posted on 1/29/03
and example image in this group (p.b.i) with the same subject.

In the future I'm going to bundle TOMTREEm.inc with POV-Tree
together with leaf and seamless bark image maps for UV-mapping.

Gena.

He is coverings his eyes. As for the leg, it may be distorted a bit, to 
avoid having it stick out of the relief.
