Isosurfaces are certainly a very handy feature.

  Could you explain how they are raytraced? I have just very vague notions
about it, but I don't know any details. It would be interesting to know the
algorithm to raytrace isosurfaces.

#macro N(D,I)#if(I<6)cylinder{M()#local D[I]=div(D[I],104);M().5,2pigment{
rgb M()}}N(D,(D[I]>99?I:I+1))#end#end#macro M()<mod(D[I],13)-6,mod(div(D[I
],13),8)-3,10>#end blob{N(array[6]{11117333955,
7382340,3358,3900569407,970,4254934330},0)}//                     - Warp -
