Code: Select all
Perfect! Here’s a clear step-by-step workflow in Grasshopper (for Rhino 7) to make a mesh from points, including irregular point clouds:
Step 1: Prepare Your Points
In Rhino, make sure your points exist as Point objects.
You can name or group them if you like.
Step 2: Open Grasshopper
Type Grasshopper in Rhino to open it.
Create a new Grasshopper canvas.
Step 3: Bring Points into Grasshopper
Drag a Point parameter component (Params → Geometry → Point) onto the canvas.
Right-click → Set Multiple Points → select your points in Rhino.
Step 4: Delaunay Triangulation
Go to Mesh → Triangulation → Delaunay Mesh (Grasshopper has a Delaunay Mesh component).
Connect the points output to the P input of the Delaunay Mesh component.
(Optional) If points are 3D, project them to XY first using Project or extract XY coordinates.
⚠️ Delaunay works best if points are mostly on a plane. For very irregular 3D point clouds, triangulation might produce stretched triangles.
Step 5: Bake the Mesh
Right-click on the output of the Delaunay Mesh component.
Select Bake → choose the layer → the mesh will appear in Rhino.
