[Bf-committers] Similar Surface modifier

Hi Daniel,

Shrinkwrap is great for initial conditions. There are two major ways in 
which it is not up to the usage I described (and please put me some 
knowledge if I'm in error here):

1. A shirt with a modeled pocket will be destroyed by shrinkwrap. Every 
vert of the wrapping mesh find it's nearest point on the target, making 
the surfaces of the pocket now coincident with those of the rest of the 
shirt. The goal of this is to leave the high res mesh (like the shirt) 
undeformed until the surface to which it is bound deforms.

2. An underlying mesh that wrinkles (exhibits concavity) causes it to 
fail in effect. The bound mesh (the high resolution) would not follow 
the bind target in and out of the wrinkle with shrink wrap -- it would 
pick the outermost point.

The goal of the Similar Surface modifier is to provide to one (complex) 
surface to another so that the bound surface follows the deformation of 
the target surface, as though it were pinned to that surface.

Thanks for your pointers on the cloth sim the other week, btw. Using the 
example you provided, I was able to come up with some very stable 
settings that produced nice results.
