Hi, Can two (or more) GrassHopper Definitions communicate in realtime? (in the same Rhino session) // Rolf

Not without plugins. You can bake geometry into the 3dm file using a Geometry Cache object, and then load that same geometry back into a tree structure using another Geometry Cache object set to the same name. But it requires a manual click to both update the shapes and reimport them. And it doesn’t…

Oh wait, you actually can use a Panel to stream textual data and a Read File component. That at least would be real-time, but it only works for textual data.

The Rhino Python sticky dictionary is shared across all GHPython instances and the editpythonscript editor within the same Rhino session, enabling one to send any data type between multiple Grasshopper canvases (and Rhino).

I saw Mateusz ran several definitions at CITA in the background. I think it was something with the bendy wall project. Do you know what was the workflow behind?

Since this is something I was planning anyway for GH2, I wrote a very simplistic implementation using standard components for GH1 in Rhino 6.0 (ignore the audio, didn’t realise the screen capture software was also recording Harmontown that was playing on my other screen).

Cool! But that wouldn’t work in GH 0.9? // Rolf

I’m not even supposed to be messing with Rhino 6.0 for non-critical stuff, let alone Rhino5.

What would be the benefit of such workflow or reasons to use it? Does it result in faster execution time or it would be more ‘clearer’ to read the gh definition??

This maybe? Pretty sure there were no stickies involved here
