BUG: delaunay mesh bake problem

Grasshopper
5

Hello, I did have a look, here is 2 quick fixes, hope they will work. They work on the file you send.
Mainly the 2 scripts suppress degenerate faces, so faces with a very small edge.
“MeshFaceList.CullDegenerateFaces”

Mesh result = mesh.DuplicateMesh();
result.Faces.CullDegenerateFaces();
mesh.Vertices.CombineIdentical(true, true);
result.Vertices.CullUnused();
result.RebuildNormals();
A = result;

double radiusSquared = radius * radius;

Mesh result = new Mesh();
result.Vertices.UseDoublePrecisionVertices = true;
Point3d vert = inMesh.Vertices.ToPoint3dArray();
for(int i = 0; i < vert.Length; i++)
{
result.Vertices.SetVertex(i, vert[i]);
}

foreach (MeshFace face in inMesh.Faces)
{
  Point3d pa = vert[face.A];
  Point3d pb = vert[face.B];
  Point3d pc = vert[face.C];

  if ((pa.DistanceToSquared(pb) > radius) && (pa.DistanceToSquared(pc) > radius) && (pc.DistanceToSquared(pb) > radius))
  {
    result.Faces.AddFace(face.A, face.B, face.C);
  }
}
result.Vertices.CombineIdentical(true, true);
result.Vertices.CullUnused();
result.RebuildNormals();

A = result;
