How would I go about fitting a subd surface to a scanned pointcloud of a classic yacht hull? It seems like a perfect surfacing tool for such a situation (and onerous in NURBS), but I am completely hopeless at subd.
Can I start with some curves and do a subd version of networksrf then fiddle to get a better fit?
The Pointcloud command will help you from a million points to select the necessary hundreds of vertices, for a rough grid as you asked for.
The MeshPatch command will help you create a rough grid.
I am very familar with the PointCloud command. It changes the data structure but does not do anything directly to help placing vertices on individual points.
That is useful information. I frequently use the Patch command but had forgotten about MeshPatch.
The PointCloud command creates a set of vertices from selected point objects or a mesh object to facilitate selection and faster display.
The point cloud object type improves Rhino’s performance when handling a large number of point objects imported from external files.
You can use the point cloud object to group any number of individual points into a single object, minimizing the amount of storage in the 3DM file and maintaining performance.
