Access "MeshPoint.T" returned by "rg.Mesh.ClosestMeshPoint()" Fast

I haven’t inspected the file yet (on my phone), but try to implement these performance tips if you haven’t already:

Grasshopper Performance - Scripting Slower Than Native Components?

Specifically for GHPython, you can usually achieve considerable speed boosts on large inputs by not using type hints or the implicit Grasshopper cycle functionality (i.e. set the access type to List if you’re operating on a list and implement the loop yourself), and on large outputs by wrapping the data in appropriate Grasshopper types: [2021-04-29 09_09_17-Grasshopper Python Script Editor] Mesh Point Remap - multiThreadTest-minimumViableFile_GHPythonFixes_00.gh (1.6 MB) See this old thread…

And if it’s still too slow you can consider threading the code, see a recent example here:

Macro to batch run "align mesh vertices"

No worries, I just had a fresh eyed look at the first overload I suggested. It’s quite a bit slower as it also aligns vertices in between meshes, but that might also be a requirement: [2023-05-31 12_14_20-Untitled - Rhino 7 Educational - Perspective] [2023-05-31 12_14_40-Grasshopper - 230531_AlignVertices_00_] [2023-05-31 12_14_50-Grasshopper - 230531_AlignVertices_00_] 230531_AlignVertices_00.gh (22.2 KB) Note that the loop-based method likely could be threaded to speed things up.
