Hellow, I have some isosurface function fun(x,y,z) that "starts" in <0,0,0> 
and ends in <0,1,0> (i.e. an isosurface cylinder <0,0,0>-<0,1,0>)

how can I transform this isosurface to get shape that starts in W1 and ends 
in W2 ? 
I need to transform the formula, not to use rotate, translate etc...

it would be something like
#declare a = W1.x + ......
fun( x*sin(a)+y*cos(a) .... )

TIA :)

#macro g(U,V)(.4*abs(sin(9*sqrt(pow(x-U,2)+pow(y-V,2))))*pow(1-min(1,(sqrt(
pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M
