Hi Anders, I have done installing ShapeOP library as per instructions, still in python script I cannot load the library.My machine is 64 bit.

Yup, that'll be an issue. If you want to run 32 bit you'll to need compile the binaries yourself (although, there might actually already be some on the ShapeOp website, come to think of it).

Hi Anders,

Why do I still have the problem of loading the ShapeOP library using ctypes when I already set the path for the GH libraries folder in windows and python editor as well put the files in the libraries folder? Do you think it might be the issue with 32/64 bit? I'm running on Rhino 32 bit btw.

Uh also, another pretty nifty constraint is a feature preserving Laplacian smoothing. I'm not sure if that is available in other GH plugins.

Hi Nik, must have missed your reply. Apologies. Conceptually ShapeOp is quite similar to Kangaroo2 (i.e. the solver is projection-based as opposed to using explicit or implicit integration methods) and has similar (if fewer) constraints currently available. I suppose that the biggest difference is that ShapeOp is written in C++ and thus could be implemented in any environment (and potentially be ultra-super-duper-fast). It does also have a few constraints that Kangaroo does not (e.g. similarity), but I'm sure one (i.e. Daniel :D) could quickly cook that one one up. I would recommend reading the papers available on the LGG website for more info and watch the videos. We also have a paper coming up for the Design Modelling Symposium which presents both the library, the GHPython implementation and some examples of how one might use it. For the low-level discussions on how the different solvers work I shall like to pass the mic to Daniel ;)

Thanks Anders!

Oh sorry, you still need to add the Grasshopper Libraries path to the Windows Path as well.

Hi Luis, we recently had a small workshop at ETH using these same example files. This issue would occur on several of the machines. In the end I got all of them working by placing ShapeOp.0.1.0.dll and vcomp120.dll only in the Grasshopper Libraries folder, unblocking them and adding the Grasshopper Libraries folder to the paths read by Rhino Python like so:

1) In Rhino type in the command "EditPythonScript".

2) In this Python editor go "Tools -> Options -> Files".

3) Here you will see an overview of the directories which are currently referenced.

4) Add a reference to the Grasshopper Libraries folder.

If you can’t see the Grasshopper Libraries path it is likely “hidden”, if so unhide it using the Windows file explorer.

Hope that helps,

/A

Hi Anders, 

do you know why i'm receiving this error message when i load sheet metal example?

Ah yes, I found that link just after commenting.

Great stuff!
