Targeted Mesh refinement in grasshopper

[Alex_Thant]

Hi, I am new to using Rhino’s Grasshopper.
How can I do the trageted mesh refinement as in the attached figure? Could someone lead me down the right path?
The document mentioned that IguanaMesh (Grasshopper module) was used.

You can use the RemeshByColour component that comes natively with Kangaroo2.

Edit: Here’s a couple of great recent examples by @laurent_delrieu:

How to control populate geometry?

You can use the power of RemeshByColour So make a mesh of your shape. Here a quad mesh to have some regular points. Measure distance to the curve for each point of the mesh. Color the mesh.

Hello you can also remesh by color [image] [image] gradient_points_triangulate_LD.gh (14.1 KB)

I think I got this eaxmple from a post of @DanielPiker but I cannot find the source anymore.

I added an option with vertex to plane proximity:

Thank you @AndersDeleuran @martinsiegrist for the quick response and answers. That’s what I am looking for. @Quan_Li Thanks for the info too.
