Hi, Mike.
Thanks, this is only a start, more serious work will follow. As to
animation, I am using very straight-forward techniques, described in
manual: https://wiki.povray.org/content/HowTo:Create_animations
and setting 'clock' variable for transformations.

I like how It works, at least now for trivial cases, may be in the
future I will need something more sophisticated.

“Give a man a fish and you feed him for a day; teach a man to fish and 
you feed him for a lifetime.” - Bible.

Many, many thanks for this example, last time you give me a fish, now
you are teaching me fishing ;). It looks like we thinking the same
: blobs are very powerful and flexible, but control is not easy and
intuitive, I spent about an hour setting parameters, trying to achieve
desired form, that I had in mind. And I started thinking about external
control, (like you do with point clouds) with CSG methods.

This is exactly what I need for manufacturing artifacts, will play with
them this night.

Happy rendering,
