I'm working on a WW1 series of aircraft and I'd like to know if anyone has
come up with a method to use a cloth simulation to emulate something like
shrinkwrap? The older planes were covered with a fabric and aircraft dope
which would cause the cloth to tense up to the underlying structure (except
where rosin/wax existed). It's not just wings, either, and includes concave
as well as canvex requirements.
Any ideas on how to proceed would be appreciated (I'd hate to have to create
a surface mesh, but I suppose I could). I'm using a mesh2 array of objects
as the group to be covered (if that helps).
Sample to be posted in p.b.i.

For quite some time now I thinking about such a system, but never got to
doing something with it. I worked with shrinkwrap on a daily basis and
always abused the machines by wrapping strange and non-smooth objects.
The results always look nice, espacialy if a black shrinkwrap is used.
I thought about is as a kind of mesh modelling system, throw together
some primitives, wrap the whole thing in a mesh of quads. Define a
certain amount of elasticity for each edge and then reduce the length of
the edges, while tracing rays to the object from the vertices.
Another idea I had about this is somehow using it for creating more
realistic "wear" textures. After shrinking is done, somehow measure the
distance from object to mesh and base a pattern on that.
I hope somebody with more math skilss and persistence will write some
code for doing this.

Could this perhaps be accomplished somehow through megapov's cloth
simulation abilities?

I hope so Mike. I'm just wondering if anyone has done anything like this and
what kind of experience they had with it (hints requested).

Uhuh, you use cling wrap machines yourself you say?

Yes, cling wrap and shrink film, but I don't use them on myself ...
