Thank You, Chris. Your include files opened my eyes for simplest morphing I
have ever seen. Perhaps this was used somewhere before but I feel like
discoverer at this moment :-) Check povray.binaries.animations after moment.

All things I had to do were:
1) prepare initial appearance of object as (ISO)CSG
2) prepare final appearance of object as (ISO)CSG
3) write isosurface functions as
      (1-clock)*POV(x,y,z) + clock*v35(x,y,z)
   where  POV and v35 are isocsg combinations

Adventages:
1) Shape is desiagned as previously as simple CSG
2) No trace, interpolate, arrays, loops were involved
3) Morphing is pretty smoth

Disadventages:
Only speed probably but since inly simple functions are involved this
limitation is controled by complexity of CSG

Now I started to dream about
1) from desert to mountains landscape like in Walking With Dinosaurs
2) from seed to tree - with morphing of surface of bark
3) from youth to old age with morphing of wrinkles on the face
4) and so on
