  pigment function as normal pattern (Message 1 to 5 of 5)

Message: <4068849d$1@news.povray.org>
is it possible to use a pigment function i've made,

#local pigf = function {pigment {... }}

as a normal pattern for an object? I understand I could make an isusurface
using that function, but that's not what I'm aiming for.

something like:

#local norm1 = normal{
    pigf(x,y,z).gray
}

?

thanks,
ross.

pretty much exactly that. This works:

#declare pigf = function { pigment { bozo } }
sphere {
    0, 5
    texture {
        pigment { White }
        normal { function { pigf(x, y, z).gray } }
    }
}

And that should work with any custom pigment function I make, no matter how
complex, right?

thanks for the clarification. I tried several variations, but apparently
never the correct one :)

Just about. It won't work wit patterns that rely on the surface, like 
the slope pattern or facets.
