C# examples?

Hi
Is there any examples how to create mesh from pointcloud, and how to use remesh and read openvdb file?
And in this example i don't find Mesh.FromAnySupportedFormat

using MR.DotNet;
using System;
using System.Reflection;
 
class Program
{
    static void Main(string[] args)
    {
        if (args.Length != 1 && args.Length != 2)
        {           
            Console.WriteLine("Usage: {0} INPUT [OUTPUT]", Assembly.GetExecutingAssembly().GetName().Name);
            return;
        }
 
        try
        {
            string input = args[0];
            string output = args.Length == 2 ? args[1] : args[0];
 
            var mesh = Mesh.FromAnySupportedFormat( input );
 
            DecimateParameters dp = new DecimateParameters();
            dp.strategy = DecimateStrategy.MinimizeError;
            dp.maxError = 1e-5f * mesh.BoundingBox.Diagonal();
            dp.tinyEdgeLength = 1e-3f;
            dp.packMesh = true;
 
            var result = [MeshDecimate](https://meshlib.io/documentation/namespaceMeshDecimate.html).Decimate(mesh, dp);
            Mesh.ToAnySupportedFormat(mesh, output);
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: {0}", e.Message);
        }
    }
}

I try this to open vdb file or fbx file but i get an error

1. An error occurred: unsupported file extension

Rhino.Geometry.Mesh MeshLidToRhinoMesh(MR.DotNet.Mesh mesh)
{
    var rhinoMesh = new Rhino.Geometry.Mesh();

    foreach (var point in mesh.Points)
    {
        rhinoMesh.Vertices.Add(point.X, point.Y, point.Z);
    }

    foreach (var triangle in mesh.Triangulation)
    {
        rhinoMesh.Faces.AddFace(triangle.v0.Id, triangle.v1.Id, triangle.v2.Id);
    }
    rhinoMesh.Compact();
    return rhinoMesh;
}

Rhino.Geometry.Mesh ReadFile(string file)
{
    MR.DotNet.Mesh mesh = MR.DotNet.MeshLoad.FromAnySupportedFormat(file);
    var rhinoMesh = MeshLidToRhinoMesh(mesh);
    return rhinoMesh;
}

Hi

Could you please clarify a couple of questions:

1. What do you mean by creating mesh from point cloud? Just triangulation or something else? Triangulation is supported in MeshLib but it is not exported to C# version yet, as well as Remesh.

2. FBX file format is not now supported by MeshLib. VDB contains volumetric data, not meshes. That's why it's impossible to read it with MeshLoad class. So what exactly would you like to do? Read a volume from VDB and convert it to a mesh? This is possible with MeshLib, but no voxel-related are exported to C# yet.

We can plan to add these features to C# version of MeshLib, but we need more info about your request.
