Umm, because that still means I have to hit render? lol
Mind, its not a bad idea and certainly one I hadn't considered. Now,
there are 1-2 on the utility page for POVRay that *do* this, but they do
so in a way that isn't transferable to POVRay code. In other words, they
do so by generating an image, not a texture SDL.
Lets put it this way. Open PSP X or Photoshop, go to something like (in
PSP) Effects->Distortion->Warp, then **see** it actually doing it in the
preview. This is quite different than manually changing lines of code,
or even tweaking a setting as in Moray, TXMag, or others, then having to
hit "run" (or preview, which is fundamentally the same thing). Its also
nicer than your solution even, since once you think you have one thing
right, you can just move on to tweak the other variables. Yours.. You
have to plug in the ones you had right, then run it again, with
different variances. Kind of annoying, even if it is feasible.
Ok, being a bit nit picky maybe, but seriously, this is one of those
things that most frontends for other engines "will" do. That you can't
even find a stand alone utility to do it for POVRay is imho, not a good
thing when you want people to consider using it, instead of one of those
fancy smancy ones that *do*. And, sometimes it just nice to be able to
do that, especially when you don't want to spend a lot of time fiddling,
even if you know how to do it the hard way. ;)

Why do you conclude that it is POV-Ray 3.6 that breaks Moray and not the
other way around?

Well.. It's hard to explain, but I belive those points are one of the main
reasons why I like POV-Ray so much. A little tweaking here, and a little there,
full control over what happens in your scene (hopefully ;) and you get what you
want in the end.
> having to hit "run"
If you don't like clicking "Run" you can press Alt+G, I find it saves a lot of
time while tweaking ;)
Try out Jpatch - http://www.jpatch.com/ - It has a very nice material editor
with a lot of sliders for pigment and finish which puts out pure, clean POV-Ray
code.
KPovModeler might also be an alternative if you run Linux, -
http://www.kpovmodeler.org/
Or you could use the provided code to do a real time preview in POV-Ray. Sorry,
I couldn't resist. :P
Jokes aside, I trie to quickly put togehter that dice you wanted, but it turned
out to be a bit harder to make it with rounded corners than I thought. It was
easy making it in Wings 3D and uv mapping it though ;)

The six vertices are x,y,z,-x,-y,-z, possibly scaled by something.
If you want rounded edges, say with radius R,
then put spheres with radius R at each vertex, a cylinder with radius
R at each edge (or, to save code, a spheresweep
x y (-x) (-y) x z y (-z) (-y) z (-x) (-z) x )
displace the triangle with vertices a,b,c by (a+b+c)*R/sqrt(3) (for
all applicable values of a b and c).
This assumes, that you do not need a solid die, i.e. your textures are
not transparent.

Just a matter of convention. Its fairly irrelevant which one breaks
which, since it just doesn't work.

Thanks, will take a look. That may have even been what I was thinking
of, though it might have been the **much** earlier cmapper and crender,
which I 'thought' had at one point been combined into something more
useful. By themselves, they are not too useful, since you can preview
modifiers in one of them, but not what it does to complex textures,
while the other lets you create the banding for one, but not *see* what
the actual result will be. Not too helpful. lol

Yeah, figured it would be complicated. Nearest idea I could come up with
was using cylinders and the blob primitive, but I am not even sure how
well that would work. It would allow adding minor components in, to make
the surface less perfect, but it might just be easier to build a
cylinder+sphere cage, then glue stuff in between the fill in. :p Or, I
could just place metal plates along the edges, instead of only having
caps on the top and bottom. Not sure yet. The one has the advantage of
looking more like its carved from "real" polished ore, while the other
would be more manufactured looking. Its a hard call.

Got to be solid, or at least mostly. I need to cave in a set of symbols,
and lettering. Basically... A broken moon on two top faces, with red
between the fragments, three shooting star like objects on the other two
tops, also red. These would us a molten texture with a displacement of
the wave pattern that matches the rotation of the object, so it pulses
as it rotates (though whether faster or slower... I haven't decided).
Guild cloak is green with red symbols (the falling stars), so I need
forest green on it too. That would be lettering, possible along the
edges, and on the bottom, in some EQ2 sort of language (Kerra, assuming
there is such a character set they use. Hard to tell, since I started at
one myself). Those also will have the molten glow effect. The main
surface is a pinkish color, almost flesh tone, while other parts are
various metallics, of the refined versions, or the grey speckle of the
"etched Acrylia" you could pick up in the old EQ1. The whole thing will
be floating over a stand on the floor, and slowly spinning.
Basically, the guild name is Shards of Luclin. Luclin being the moon
that the city of the Vah Shir (Luclin's Kerra) stood on, before the moon
exploded in between EQ1 and EQ2. The textures are all from the material
"Acrylia" that 90% of the armor that you crafted there was based on.
No idea what I will do with the rest of the room yet, but I wish there
was some way to get a better look at ingame textures on items like the
Shade Silk cloaks and stuff, so I could see if they where unique enough
to try to duplicate them for tapestries or something. This 8 sided thing
is just step one. lol
Am I crazy wanting to do this for a web page, or just overly bored?

Latest version, I think, doesn't seem to allow color maps, effects on
those maps, and some of the basic controls, in the modeler part,
themselves didn't work for me.. Basically, its texture system is what
crender did. Settings for basics, like transparencies, metallic
finishes, phong, etc, but no way to do what I need, which is play with
banding and the like. Guess I am going to have to go with the hard way
at this point. Almost as much of a pain in the ass as finding out that I
need the "raw" unpatched EQ1 Titanium to log into the emulation server
(s), so I can look around for textures and stuff to use in other parts.
I ain't paying Sony more money to log into that again, just to get
screenshots for design ideas... :(

In that case replace the triangles with something solid.
The easiest would be an eight of an octahedron: For the triangle with
vertices a, b, and c this would be
intersection {
plane { -a 0 } plane { -b 0 } plane { -c 0 }
plane { a+b+c 1/sqrt(3) }
translate (a+b+c)*R/sqrt(3)
}
Keep in mind, though, that carved dice are not considered fair.

Decided to use the one in shapes2.inc and just scale it, thought that
means, at some point, lopping edges off and replacing them with
cylinders, etc, to round it. Got a different problem though. The
texture... So far I have this, which I am not real satisfied with:
texture {
pigment {marble
turbulence 0.85
color_map {
[0.00 0.40 color rgb <0.66275,0.57647,0.58824>
color rgb <0.65882,0.56078,0.57255>]
[0.40 0.72 color rgb <0.64275,0.55647,0.56824>
color rgb <0.63882,0.54078,0.55255>]
[0.72 0.95 color rgb <0.62275,0.53647,0.54824>
color rgb <0.61882,0.52078,0.53255>]
[0.95 1.00 color rgb <0.57775,0.49147,0.50324>
color rgb <0.57382,0.47578,0.48755>]
}
}
What I am trying to do is duplicate the colors in this:
http://everquest.allakhazam.com/pgfx/item_1138.png
but looking more like:
http://everquest.allakhazam.com/pgfx/item_1095.png
Though, in fact, I plan to use "both" color sets for different parts of
the item I am building. And, since this is going to be a *large* object,
I want to make at least one band in it so that, instead of having the
reflective qualities of polished stone, it has granular crystal like
veins, which have a metallic finish. So, what I am looking for is
something like:
texture {
pigment {marble
turbulence 0.85
color_map {
[0.00 0.40 color rgb <0.66275,0.57647,0.58824>
color rgb <0.65882,0.56078,0.57255>]
[0.40 0.72 color rgb <0.64275,0.55647,0.56824>
color rgb <0.63882,0.54078,0.55255>]
[0.72 0.95 color rgb <0.62275,0.53647,0.54824>
color rgb <0.61882,0.52078,0.53255>]
[0.95 1.00 color rgbt <1,1,1>
color rgbt <1,1,1>]
}
finish { stuff to make it polished stone }
}
texture {
pigment {marble
turbulence 0.85
crinkle
color_map {
[0.00 0.95 color rgb <1,1,1>
color rgb <1,1,1>]
//Darkened to enhance the vein like appearance.
[0.95 1.00 color rgb <0.47775,0.39147,0.40324>
color rgb <0.47382,0.37578,0.38755>]
}
finish { stuff to make it metallic }
}
Right? Can just try it, but wouldn't mind some input on how to get the
texture itself a bit closer to what I want as well.
