Help with gradients and distance points

[Constanza_Q]

I’m trying to create a gradient map based on the distances between two objects. I have the list of distances and their corresponding points (vertices), but when I apply them to the mesh, I get a noisy/grainy gradien. This happens even though the longer distances are physically located at the lateral parts of the sample. I have ensured that the list lengths match and all inputs are flattened. Any insights on why the vertex indices might be mismatching or how to fix this visualization?

Hello
you have to understand that you must provide a color for each vertex of the mesh. So for each point of the mesh you make a calculation.
Also I understand that

between two objects

But you have 3 objects ?
So with 2 objects, a surface and a mesh here is a way

@Constanza_Q

how to fix this visualization?

Seconding what Laurent already inquired about (more than 2 meshes), did you intend to colorize both meshes based on their distance to the surface?

Pretty much the same as Laurent’s example, just brings in both meshes:
