plugin application dataflow geometry grasshopper rhino3d
Credits: readme, joreg, phlegma
This plugin allows you to easily send geometry and other data from Grasshopper for McNeels Rhinoceros to vvvv in almost realtime.
The data is stored and exchanged via an *.vltr file. So you can also use it via a network folder or send the file to somebody else.
If you want to contribute just contact me!
You can find the code at:
This plugin will be part of the Grasshopper & vvvv Workshop at NODE15
This is amazing! I was literally just looking into making this, and got a tip off that it already existed.
if anyone figured out how this works, pls post some instructions
@antokhio, it does work: Try the example file by opening the: Vulture (Grasshopper Receiver) help.v4p in vvvv and opening the vultureDefinitionExample.gh in GH, then start the GH timer. In vvvv load the test.vltr file that GH creates; in GH make sure the address and name are correctly point to test.vltr (that's a main reason it may not work). You can then interact with the geometry in GH and it refreshes in vvvv. (you also need to unblock the GH files in Windows > right-click > properties > unblock)
another important thing is to make sure that the filenames match up between the 2 (i used absolute paths)
note that the grasshopper plugin always adds a .vltr (even if the filename you give it already has that extension)
look out for the file that it's creating, and make sure to select that file on the vvvv side
it's pretty trivial to recode for dx11 on the vvvv side
another note : can be pretty slow with anything more complex
be great if there was a background thread on the grasshopper side with a lower update rate to write out the vertices, and also if something like IPC (e.g. via zmq) was implemented rather than via disk (which can be slow even when using RAM cached disks)
What versions of VVVV and Grasshopper does this require? I have GH 0.9.0076 and VVVV 45beta34.2 x64 and cannot get it to work in either. I have the four files from the Grasshopper folder copied into my GH library folder, and I've placed the two VVVV files into VVVV\packs\vulture
Grasshopper gives me a red balloon, stating that the assembly cannot be found: "1. Solution exception:Could not load file or assembly 'vulture, Version=126.96.36.199, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified."
VVVV node, when pointing to the supplied test file, alternates between red node and grey every few seconds, with no output in either state.
I have a feeling I've just placed something in the wrong folder, or pointed something to the wrong location, but I've exhausted all ideas.
Aha! I've found the solution. This may be specific to Windows 10. The .zip file must be unblocked before the files are extracted. Unblocking the individual files after they are extracted does not work.
I tried this, but keep getting an error in Grasshopper. I did the unblocking of the zip file.
I am using the latest Version 0.9.0076.
Also I would suggest using the File Path component and not adding the file extension in the vulture component. That way you can just right-click and "set one filepath" rather than typing in the file path without the file extension, which makes no sense.
EDIT: Forgot to unblock the slimDX.dll file, dohh!
