algorithmic modeling for Rhino

mesh from point cloud

HI guys
I have a problem hope somebody can help me.
I have a set of random points in 3d is there any way to make mesh or Nurbs surface out of them so that I will have closed volume (like 3d convexHull) and if there is any way to control clustering of this surface

Thnx in advace
Alex.

Hi Alex,

there are a number of algorithms available that are typically used to do this, but none of them are part of the Rhino SDK. So you'll have to code them up from scratch or find some library out there which you can use.

You can look into:

- Delaunay (both 2D and 3D)
- Cube-marching (how the MeshFromPoints command works)
- Meta balls
