Mesh from point cloud?


#1

Hi,
I’ve tried meshpatch, meshfrompoints, but neither are very good, I’ve tried a trial version of VRMesh which works well, then I saw the full version is £1700!!.. any advice on a cheaper alternative, preferably within Rhino

Thanks

Grasshopper>Delaunay…? Cost 0$… but you will need to explode your point cloud or script a Grasshopper component to do so, as Grasshopper cannot reference point clouds…

Does the point cloud represent a surface or a volume?

Do the points and the mesh vertices need to coincide?

If the point cloud represents a surface and the mesh vertices do not need to coincide with the points, then try using Patch to generate a NURBS surface and then convert the surface to a mesh.

It’s a volume, 3 statues of people. Actually when I exploded the point cloud and then did the Meshfrompoints command I was given a mesh, I’m not that happy with the mesh but I think it’s down to the point cloud information, it can only use what it has and I don’t think it’s detailed enough for a detailed model.

Though I would also like to ask, I exported a mesh to 3DS Max to see if I could clean it up, it was really hard to manage, to do anything with, any tips on exporting this to Max?

If you don’t mind trying out new tools, you might be interested in the Point Cloud Skinner add-on for Blender. See http://blenderartists.org/forum/showthread.php?241950 for information on the add-on.

Hi Mart,

if you can post your pointclouds or send them via pm i can try to mesh them or show how to do it using free software.
