Sometimes I feel quite dull... Do you mind if I ask a dull question?  Well
for those who don't mind: I have a vector. How do I rotate a cylindrical
pattern, so it faces towards that vector? Example:

#declare Vector=<257,47,2>;
#declare Origin=<0,0,0>;

cylinder { Origin,Vector, 1
    pigment { cylindrical rotate Vector? }
}

It's so easy, right ... so tell me... :o} I already tried a bunch of things
and I'm getting tired.

Thank you,
Hugo

Should be easy with the Reorient_Trans(Axis1, Axis2) Macro in
transforms.inc, Axis1 should be y, and Axis2 your Vector. Did not test it,
but IIRC this should work.

Use the Reorient_Trans() macro in transforms.inc.

#macro M(A,N,D,L)plane{-z,-9pigment{mandel L*9translate N color_map{[0rgb x]
[1rgb 9]}scale<D,D*3D>*1e3}rotate y*A*8}#end M(-3<1.206434.28623>70,7)M(

Thanks guys, I was browsing around math.inc and forgot about
transforms.inc.. It works now, I'm just having some other problems.. Maybe I
should let it go, until I've slept.

Or just use Point_At_Trans(Vector).
