Hi all!
There's something I still can't find in the documentation. In Section 6.7.12
about Pattern Modifiers it is:
"The general purpose pattern modifiers in the following sections can be used
with pigment, normal, texture, or density patterns."
So I'm not allowed to use a "repeat warp" for an object pattern? Is there a
workaround for this purpose or do I have to use loops?
Best regards,
Florian

Do you mean something like the following?
// warp with object pattern test in version 3.5 beta.
camera { location <0, 0, -7.75> look_at 0 }
light_source { <10, 10, -10> rgb 1 }
box { <-5,-1,0>, <5,1,1>
pigment { object { sphere { <0.5,0,0>, 0.45 } rgb <0,0,1>, rgb <0,1,0> } warp {
repeat x } }
}

It doesn't say anything about specific patterns. It lists "pigment,
normal, texture, or density patterns"...in other words, pretty much any
pattern. The object pattern can be used for all of these, and the pattern
modifiers work fine for it.

No because that's repeating the whole pigment. I use pigments for the rgb
values in your example and only want to repeat the inner pigment (in your
Example rgb <0,1,0>). So basically I want the sphere pigment to repeat but
not the pigment out of the sphere.
Here's the relevant part of my scene:
pigment {
object{
cylinder{<0,-2,0>,<0,1,0>,0.2}
pigment { //This pigment shall not be repeated
wood
warp {
turbulence <0.2,0.2,0>
}
frequency 40
color_map {
[0.00 color <190,123,88>/256]
[0.90 color <172,106,70>/256]
[0.99 color <127,83,61>/256]
[1.00 color <88,42,8>/256]
}
ramp_wave
rotate <0,90,0>
scale <2,2,2>
warp {
black_hole <0,0,0>,.5
strength 1.5
inverse
repeat <1,0,0>
}
},
pigment{ //but this pigment
wood
turbulence <0.02,0,0>
frequency 20
color_map {
[0.00 color 0.5*<150,113,88>/256]
[0.90 color 0.5*<142,96,70>/256]
[0.99 color 0.5*<127,83,61>/256]
[1.00 color 0.5*<88,62,48>/256]
}
rotate <90,0,0>
}
}
}
Thanks for the help,
Florian

That's fine! Thanks, please have a look at my problem in the reply to Robert
Chaffe.
