If you explain what you mean with this someone might be able to answer.

Remember POV-Ray is a renderer, not a modeller.

Yes, no and even more :-)
Yes - you can displace vertices and subdivide triangles in meshes if necessary
with smart macros in your favorite way and then it works similiar to the way
triangle based modelers handle it.
No - you can't freely displace primitives due to mathematical formulas used to
tracing them but they are not available in trangle based modelers so it is not
aplicable to comparison.
Even more - you can displace isosurface in easy way with better quality than
triangle based meshes but it takes computation power.

You apparently misunderstand how POV-Ray works. For a quick answer please
read this manual section, which gives a sufficiently short explanation:
9.1.1.11 How can I bend a object?

"yes"
Documentation: 7.12.1.1 The HF Macros
"even more"
http://news.povray.org/povray.binaries.images/29800/211748/f_teapot.png
http://news.povray.org/povray.binaries.animations/23891/167475/wip.mpg
and a lot from Tor Olav Kristensen
http://news.povray.org/search/advanced/?s=Kristensen&g=povray.binaries.images&a=1
but that good operating with possibilities of 'yes' and 'even more' cases
require understaing of 'no' answer.

BTW, did you ever finish the morphing texture or make the scene source
available?

Current irtc animation topic asks me the same
and I hope I will say 'yes' some day.
