Here is my current project and two questions:

* Why can't I get blobs blobby? This is my first attempt with blobs, and as you
can see there is a sharp edge where the bump making spheres intersects the ball
sphere.

* How do I prevent the image maps from appearing at the reverse side? I've
tried gradient texture maps, but was told that texture maps couldn't be used in
layered textures. (or something)

While I can't answer your first question, here's a link to a tutorial
dealing with your second:

Are you enclosing the ball sphere and the bump spheres in a single blob{}
statement? If you have them in separate blob{} statements, they won't blob
together when they intersect.

Nice tutorial, but it didn't solve my problem. 

Now I've tried material maps too, but I get the same message when I try to use
them in layers: "Cannot layer a patterned texture over another"

'threshold .8' might be a little tight, perhaps lower that.  'blob' hardly ever
loses it's creases between components completely though.

First, decrease your threshold to .1.  As for the intersections, you should make
multiple copies of the objects you wish to blob. Make the components increase in
diameter, and decrease the component power.  This "feathers" the edges, resulting
in a much smoother edge.

This actually works just fine. The texture on my sports car is entirely dependent
on this working just fine. my suggestion is to experiment.

Here's a code snippet from a drinking glass I made using a different
technique.  Basically you create a second object (slightly larger than the
original and hollow), apply the logo image map to it, and chop off the back
half by differencing it with a box.

// make a drinking glass from the difference
// of two cylinders
#declare GlassMain = difference {
  cylinder {
    <0,0,0>,
    <0,Hite,0>
    Rad
  }
  cylinder {
    <0,0.1,0>,
    <0,Hite+1,0>
    Rad*0.9
  }
  material {GlassMat}
}

// make another hollow cylinder with a slightly larger
// radius than the drinking glass and chop off the back
// of it by differencing it with a box
#declare Logo = difference {
  cylinder { // main cylinder
    <0, -0.7, 0>,
    <0,  0.7, 0>
    Rad+0.00002
  }
  cylinder { // cut-out
    <0,-0.71,0>,
    <0,0.71,0>
    Rad+0.00001
  }
  box { // chop off the back half of the cylinder
    <-Rad-0.1,-0.71,0>,
    <Rad+0.1,0.71,Rad+0.1>
  }
  texture {
    pigment {
      image_map {
        gif "logo_image.gif"
        transmit 209, 1.0 // make the background of the image transparent
        once
        map_type 0
        interpolate 2
      }
    }
    // scale the logo to fit
    translate <-0.5,-0.5,0>
    scale <224/167,1,1>
    scale 1.4
  }
  // position the logo cylinder on the drinking glass
  translate <0,3.75,0>
  rotate y*11
}

#declare DrinkingGlass = union {
  object {GlassMain}
  object {Logo}
}

Thanks! It's quite simple actually. I got it pretty much at first attempt:

$Green=
pigment { bozo
    colour_map {
        [0 rgb <255,249,227>/255]
        [0.5 rgb <233,255,227>/255 ]
        [0.8 rgb <219,205,150>/255 ]
        [1 rgb <255,249,227>/255]
    }
}
$Svart=
pigment { ripples
    colour_map {
        [0 rgb 1]
        [0.8 rgbf <131,105,55,90>/255 ]
        [1 rgbf 1]
    }
}

(see previous posting for the rest)

That worked like a dream, thank you very much.
It must feel great to have control of these evasive shapes..

Hopefully this will help. I'm not the linkmaster Ken is, I only know of this on

Hm, yes, using radial is a bit more elegant than gradient. Ah, well who cares
as long as it works.. 

I also found a thread in this group concerning my other problem:

but I got around this since I didn't actually need a texture_map, just a

Btw I'm planning to make a bunch of baseball artifacts for the Knickers web

Very nice image.  You might consider Rhino for making that glove.  You can
download a fully functional demo that limits you to a total of 25 saves.  It
exports to POV and is VERY powerful.  If you're a student they offer a great
discount (my wife just started back to school to finish her MBA... time to
buy it!!!).

That was 15 uses last that I checked (the day before). If you can keep
an uptime of two or three days you'll learn most of the stuff you'll
need. The tutorials are good and the help, though a bit on the
reference side, is, well, quite helpful. I was able to create a pretty
complex (for me, anyway) model in less than 6 hours and I don't think
I am any exception to the learning curve statistics.

They must have changed it... I just checked mine and it said I have 25 saves
left (I haven't made anything good enuf to save yet).

I'll check it out. I've seen some very nice models done with Rhino, but I
didn't know there was a trial version. How good is the pov-export? Do you
have good control of object groups/unions?

The POV export is pretty good. It can export a big POV file or a small
POV file and a separate INC for every object. It would have been good
if all elements on a layer could be made into a single mesh, but even
now preparing a 50 MB exported mesh for rendering takes about 5
minutes.

Thanks, and yes. A bat with 100 inch radius.

I don't get it. 
But then again I didn't get your statement about gifs either. Surrealism?

personal to me:
Are you sure that personal to you?

Jr is now #30
Is it because of your plans that you say jr is now 30?

But who will break 714(?)
Does it bother you that who will break 714?

Mac or the Cry Baby?
Is it because of the people you hang around with that you are going through
all this?

I am seriously considering registering it. I'll have to see the terms
and conditions for a student's license and of course I'll have to
figure a way to pay (I hope they accept cash).

If I recall from reading their web page (emphasis on "if") it's just a
discount on price... same terms and conditions.

Yes. But then I have to make the maps 4 times bigger, cause they wrap all the
way around. And I like to keep memory usage down. I'm using a radial pigment
map now, just as Josh English suggested earlier in this thread.

4.7.8.9.1 The once Option
Normally there are an infinite number of repeating image maps,
bump maps or material maps created over every unit square of the
x-y-plane like tiles. By adding the once keyword after a file
name you can eliminate all other copies of the map except the one
at (0,0) to (1,1). In image maps, areas outside this unit square
are treated as fully transparent. In bump maps, areas outside
this unit square are left flat with no normal modification.  In
material maps, areas outside this unit square are textured with
the first texture of the texture list.

For example:

  image_map {
    gif "mypic.gif"
    once
  }

A cylindrical image map will wrap all the way around the ball, regardless of
wether once is used. My png-s are covering an 40 deg. angle. To avoid they
getting stretched beyond recognition, I would have to make them looong.

Never tried this myself, but try using "once" and "frequency" on a radial
map.
Another possibility : radial texture_map with something like:
[0.00 texture{myImageMap}]
[0.25 texture{myImageMap}]
[0.25 texture{Invisible}]}]
[1.00 texture{Invisible}]

I hope this helps,

Povingly

Thanks for your time, but as you can see from previous posts, I have solved
this. You would also see that texture maps cannot be layered..
