I’ve exhausted my abilities and what I can find here and online to solve my issue.
So far I have generated a “split guide curve”, deconstructed the “input mesh” and found the closest vertices to the curve points on the mesh.
I would now like to create a curve which ‘snakes’ from vertex to vertex linking them along shared edges (yellow line below)
Many of the vertex points (red in the image above) are in close proximity, but in areas where points are missing (purple circle), this poses a challenge I am unsure how to solve.
What I have attempted and researched:
David Rutten’siterative proximity script which I’ve included in the .gh
I’ve also attempted to build geometry around the curve to capture more data to compensate, but for my use case more accuracy is required
Unfortunately, this creates irregular curves and deviates from the mesh vertices. (orange)
Through my research I’ve come across the shortest walk and how this can be used to travel between two points. Unfortunately, I have not been able to figure out how to apply it to my use case.
Any help would be greatly appreciated
