try loops and macros

i.e.:

#macro SphereLine (startpt,endpt,rad,nsegments)
    union{
      #local i=0;
      #local seglen=(endpt-startpt)/nsegments;
      #while (i<=nsegments)
          sphere{0 rad translate startpt+seglen*i}
          #local i=i+1;
      #end
  }
#end


use like:
object{SphereLine(<-5,0,-5>,<2,1,2>,0.25,100) texture{MyTexture}}

creates a line from pt1 to pt2 using 100 evenly spaced spheres of radius
0.25
