algorithmic modeling for Rhino

Boundary Curve or Surface or Mesh constructed with Points??

Hi there!

I would like to create a curve or a surface / mesh, controlled by a points cloud. The points are in the XZ-plane - I added a rhino file.

I can't figure out how to generate a surface which has its boundary close to the points, like in the picture. I hope you guys have some good ideas!

Thank you :)

Hello

yes it is possible, almost everything is possible in GH as you could program it. But here with simple components, here is the trick. Use Delaunay triangulation to get the envelop but as you may want changes in Z, I first scale down the point in Z (rescale with 0.01) and then delaunay and then suppress triangles that have too long edges. rescale at the end. After that you could join the mesh, extract contours ...

Choosing the "second number" slider enable to filter the face with a too long edge. Look at the differences with 2 values of this number. 

Trick : -1 in list item allows you to get the last value !

Hope it helps. 

And if you don't want to cross z=0, add point with z=0
