but as I answer to Chris main part of my concept is using "bi-directional"
deformation and if warps support it this could be possible
but I'm affraid it is imposible

no, they aren't simple, only twister is simply
is this simple to calculate x from (A*x-B)(cosx-sinx)=C ?

this is misunderstanding
you think that I want function for whole space but I don't want
I want container for base space and deform function
with this I can describe space of deformed object and bound it
during trace I can recognize steps inside deformed container and undeform

are you curious about placing along spline ?
just like 2d drawing software puts text on curve
I'm not sure if it is possible but perhaps this is beginning:

1. get spline (begin at t=0 and end at t=1)
2. generate function for normal N=f(t) where t is beetween 0 and 1
3. generate function for point P=f(t) where t is beetween 0 and 1
4. generate equation for plane at point P(t) and with normal N(t)
5. resolve equation to find (perhaps derivative of sth) plane
    with minimal distance beetween my point and P(t)
6. calculate t for achived plane

looks this possible ?
