Tiling a curved surface with a white-to-blue gradient

[laurent_delrieu]

Hello
finding center lines is not an easy task as center is not well defined. It seems best to draw the center lines using Rhinoceros.

I tried an approach that could help you a bit. The idea is to put weights on high curvature parts. Then smooth the weight using some smoothing or “Heat”

Heat Method

A script demonstrating the Heat Method for Distance Computation, as described here This came up recently in another thread, and I thought others might find it an interesting example. It is a fast way of getting approximate geodesic distances from a given point to all points on a mesh. Here solved in an iterative fashion, without any extra numerics library. This is not the fastest way to do it, but it does let you see what’s going on and interact with it. HeatMethod2.gh (163.7 KB) (*edi…

here I use my tools from Nautilus

Then I transform the weights on vertices to a Vector field.

Mesh iso splitting could also help
