Grasshopper

algorithmic modeling for Rhino

OK, so I've been working on this problem for a few days now. Basically, we've done a series of tests draping heated polystyrene over wires we have strung in a mold. We'd like to use some type of digital simulation to test out larger systems and different variations without having to do as much physical mock-ups to speed up the process.

I've been using grasshopper and kangaroo to simulate the effect of vacuum forming the panels using the anchor spring component. I have a series of lines that are drawn over my mesh that I subdivide and plug into the anchor spring component before attaching to the kangaroo physics engine. So this has worked so long as the lines that I use are perpendicular to the mesh and the subdivided points along that line sit directly on top of the mesh points. Here's the definition that I've been using so far, the rhino file and an animation.

My system seems to be working out pretty well with orthogonal wires, but the issue I've been having is I'd like to approximate an angled wire with the deformed mesh. I've been trying to use the collide surface component, but I get some odd results with the resultant mesh.

Anyone have any thoughts on this? I've been trying to look through the kangaroo documentation and the grasshopper forum, but I haven't quite figured out how to make it work yet.

Thanks!

The end goal we're looking at is creating a wall system that can have a shift in geometry throughout the series of panels while still using the same mold.
