Am I doing it wrongly, or is it impossible to #declare a warp? Povray even
_crashes_ when I try to get around by using a #macro.

I tried this:

#macro Foo
turbulence 0.4
#end

And later:

object

    something_nice_as_well
    pigment {
        marble warp { Foo }
    }
}

This causes Povray to crash. I also tried to wrap the warp-statement as well
into the macroa dn just calling the macro to place it like this:

pigment { marble Foo }

But Povray didn't like a warp in a macro.

Anyone who can explain?

TIA,
Simen Kvaal.

  Yes, I'm impossible to #declare.

I don't think you can declare a warp. However I have no problems using it in a
macro:

#macro Foo()
    turbulence .2
#end

sphere{
    0,1
    pigment{checker rgb 1, rgb 0 Foo()}
}

Works just like expected, both in regular 3.1g and MegaPov 0.5 (Windows). What
version are you using?

You appear to have forgotten the parentheses in your macro call.  Try this:

object

    something_nice_as_well
    pigment {
        marble warp { Foo() }
    }
}

Maybe you already realize this, cannot declare a keyword for use later.
#declare Turb=turbulence 0.4
would need to be retrieved as:
warp {turbulence Turb}  anyhow.  If that's possible to begin with anyway in a warp, I
didn't check.

Ah! That might be the problem. But seriously, Povray shouldn't _crash_ on
me, performing "an illegal operation", when stumbling into erroneus
scripting ...

I also find it somewhat inconsistent not to be able to #declare a warp;
what's the logical difference between a warp-block and a, say,
pigment-block? I have to say it would be very convenient to be able to do
so.

Simen.

Oh no! I should have expected that! :-) But I _can_ declare you:
for example:

#declare Warp =
pigment {
    checker
    color rgb <1.0, 0.77, 0.94> // yuckish pink color for my dear Warp. ;-)
    color rgb <1.0, 0.32, 0.83> // saturate the pink, yuckish color a bit
}

*chuckle*

Simen.

Correct me if I'm wrong but a warp is a kind of transform, so have you
tried declaring it as such?

No, transform does not take a warp; it only takes general transformations
(translate, rotate, scale, matrix).

I would prefer:

pigment { checker Blue, White }
