I’d like to call MeshFromPoints from Grasshopper. MeshFromPoints only exists as a .rhp file, and not exposed in the C# API. So, I think this is done via the PlugIn system, according to this post.
(Inside a Grasshopper C# component)
using Rhino.PlugIns;
...
var path = "C:\\Program Files\\Rhino 8\\Plug-ins\\MeshFromPoints.rhp";
PlugIn.LoadPlugIn(path, out var plugInId);
// plugInId is 00000000-0000-0000-0000-000000000000
var myPlugIn = PlugIn.Find(plugInId); // this doesn't work, the result is null
The plugInId looks wrong, but, there is no error. If I misspell the filename I do get an error. So maybe this ID is correct?
I feel like I’m approaching this incorrectly. I’ve read the PlugIn docs. I found this post which makes me think I need to use PlugIn as a superclass, but even still, I’m not sure what to do if I do this,
public class MyPlugIn : PlugIn {
protected override void CreateCommands() {
base.CreateCommands();
}
}
Hi @dale
Broadly, I’d like to automate the process of mesh-ifying a pointcloud. I was hoping to have a Grasshopper C# component which runs MeshFromPoints. Input-PointCloud, Output-Mesh.
The MeshFromPoints plug-in contains a single MeshFromPoints command - it has no callable API.
Ah, I see. I guess what I’m trying to do impossible? Is there any other way around it?
As far as creating meshes from point clouds, you might search this forum, and the Internet for that matter, to see what others are doing.
A quick Google search give me this:
I’m sure there are other techniques.
Regarding the MeshFromPoints command, I don’t know if there is a clever way of automating this using Grasshopper - a question to ask in the Grasshopper category.
Thanks @dale !
My colleagues actually looked at a lot of other options and everyone prefers Rhino’s MeshFromPoints. It’s very good! We would settle on a not-fully automated workflow if it means using MeshFromPoints.
