Hi all, I’m currently trying to write a grasshopper definition that takes a mesh (3d scan imported as an obj file with color) and converts coloured lines on the mesh to curves. [scan%20with%20texture] I’m able to get only the vertices with a certain color. But in a next step i want to fit a curv…

In this case, Sequential Closest Points from neoarchaic could be useful. [image] Sequentially Sort Points by Distance From a sample point a list of points will can be sequentially sorted by marching through each closest point until the point list has been exhausted. …

That’s exactly what i was looking for Thanks!

How to select vertices with a specific colour, and fit curve through a subset of these vertices?
