I want to add the bezier_spheresweep.inc and blending_polygon_circle_shape.inc
files to the exporter.
You can enter in them GPL LICENSE BLOCK and the authorship?
I can't violate your rights for authorship!

Oh, I didn't see your message until today. Um... basically I'm willing to share
the macros to your exporter. It is also a good news for me. But in fact there
are still some minor bugs on the macros; and I have another version for the
'polygon to circle blending' macro. I would like to rearrange them and it will
need several weeks because I participate in a training about video producing
these days.

Okay, I will add an authorship and the GPL LICENSE BLOCK.

Thanks!
GitHub allows to make changes to files. I will always update if you improve
them.
Now blending looks so:

And, you watch my screenshots. I can create in the Blender everything, including
sphere sweep. Export and parsing is time. I consider that macros save time. I
hope that Povray will read and will calculate a macro quicker, than
blob {
object { sphere matrix }
object { sphere matrix }
and so on 100500 objects sphere
}

Actually, the current parser's macro and loop performance is rather
poor; if you want fast parsing, you're always better off just writing
one huge file without any loops or macros.

One of the worst things you can do is place a macro in an include file,
and call that macro a lot from the main file. This will cause POV-Ray to
repeatedly open and close that include file for each and every macro
invocation.

The only thing that can actually save time is functions.

Thanks.
Sadly.

And this is exactly how both And and I implemented sphere sweep unions 
and merges (by calling Connect_Spheres() in shapes.inc).  Still, the 
parse times seem negligible, probably due to file caching.

Nevertheless, you have now persuaded me to write a substitute for VEq() 
in SphereSweep, especially since, for that module's purposes, the 
arguments needed preprocessing anyway before passing them to VEq().

I also think so. Although I'm not so professional on this working. Of course you
can save time on exporting the huge file.
