Thanks alot man, much appreciated.

Thank you very much.

Cheers mate, looking forward to having a play with this!

thanks for sharing!

can this shrink wrap be done in reverse? so it inflates into a shape but deforms when colliding with the shape. for example a sphere in a box.

thank you for sharing!

Daniel,

If you're dealing with orthogonal surfaces, you could probably isolate the interior surfaces and then use this definition on that...and then the inflation can be done by making the pressure level positive.

As I see it, this would be difficult to set up for generic geometry.  I think you would have to develop a way to make an inscribed bounding box, which would require a hollowed structure. 

I think a more physically accurate shrink wrap can be developed with kangaroo, where you can put the shrink wrap on the inside or outside surfaces, but as of now, the brep collision properties aren't working as rigidly as we would need it to.

The simple one worked really perfectly for me! But the Kangaroo version seems to have a lot of issues with the Weaverbird components, I can only get it to work (somewhat) when I bypass those... Is there some kind of conflict between WB and the newest build of Grasshopper, it keeps giving me 'invalid meshes'? (I use 0.8.0066)... (Well, I might also just be doing something wrong, it is a slightly complicated definition... for me anyway! :)

Jorn,

I had an issue with invalid meshes in the previous version of Weaverbird. Have you updated to most recent?

I might have an old version of WB... I'll try to update and see if that works... Thanks:)

Yes! My version of Weaverbird wasn't updated, It works fine now, thank you!

great share.... thanks

Meria,

The negative pressure is the only function right now that makes the wrap tighter.  Since the bounding box is connecting to the nearest point on the geometry, the wrap will not attach to concave surfaces.  You could try to subdivide the mesh again and then drag the new vertices to the surface, but that may get a little complicated.

Thanx Erick,

would the results be same if the brep to be wrapped is a set of geometries imported from 3dsmax or sketchup???

also....... is it just my system or the eventual wrap can not be baked?

The mesh is probably not baking because it's invalid (see posts below).  If you update to the newest version of Weaverbird, it should work.

some parts of the grasshopper cannot see clearly. I find it hard to figure out. Can you share the grasshopper file here? Thank you !

Trying to get this working but the data flow seems to stop at "ReRoute Cluster"  Any suggestions.

Thanks in advanced.

Hi Erick,

I'm exploring your shrink wrap definition and having some trouble getting the mesh to work when turning on kangaroo. The object individually wrap, but it's broken where you would expect the shrinking to occur. When I turn kangaroo on I can get it to connect by turning up the glue range. The problem here is that the faces are triangulated instead of smooth.

Thanks!

Hi Erick,

This script is exactly what I've been looking for but with all of the updates, the script is outdated and cannot find the appropriate replacement components. Do you have any suggestions on repair or replace for the following outdated components?

1. ReRoute Cluster (input=BBoxMesh output=Mesh)

2. KangarooSetupCluster

Thanks ahead for any advice.

same question as Kurt.

It would be great if you can update the definition.:)

I've finally gotten to update this. Check out the post above for a newer version.

I'm getting "null" for all the forces. Do you know any way to fix that? Thanks!
