Hallo!
How can I define a function that constructs an object depending on a
parameter?
For exampel

ball(t, r)

should give something like

sphere { < t, 0, 0> , r}


Bets wishes             Jan

  Not possible with a function, but with a #macro it's easy:

#macro ball(T, R)
  sphere { <T, 0, 0>, R }
#end

-- 
#macro N(D)#if(D>99)cylinder{M()#local D=div(D,104);M().5,2pigment{rgb M()}}
N(D)#end#end#macro M()<mod(D,13)-6mod(div(D,13)8)-3,10>#end blob{
N(11117333955)N(4254934330)N(3900569407)N(7382340)N(3358)N(970)}//  - Warp -

OK, thanks a lot for the fast answer.
