Random Height and Surface from Points

Hi Fabio,

SuraceFromPoints works on a uniform grid. If you SDivide a a trimmed surface then you are missing some of the points that define the grid as they fall outside the trimming boundary.

Attached is an example of a trimmed triangular surface and an untrimmed triangular surface (made from 4 points instead of 3).

Just change the toggle value from true to false to see the difference.

I see but that is probably going beyond my 'beginner understanding' of GH. I thought I made my way around it using Meshes. It works when I use the mesh on xy plane but if I change the base plane... things aren't working any longer, although the rest of the parameters are left unchanged. The only change is applied on the move vector. It cannot be that the problem, right?

Delauney doesn't guarantee to rebuild a mesh. As far as I'm aware, the algorithm is designed for horizontal surfaces.

use Decompose Mesh (mComp) to extract the veritces, move them any way you like (as long as their order remains) and rebuild the mesh with Mesh.

Thanks Hannes. That worked as I wanted it.

here a pic of the studies I'm developing on a responsive structure.
