Particles to mesh

[SimonNgj]

I have a point cloud and I would like to do mesh reconstruction for that point cloud. At the moment, I am following this procedure:

1. Consider point cloud as particles
2. Convert particles to Level set
3. Apply Dilation -> Smooth filter -> erosion -> convert volumeToMesh
   I get the mesh after applying these steps, but the the mesh is in a rim shape. I want the mesh to be a single layer, is there any way to achieve that?
   I attach below an image to illustrate want to achieve

From this image, (a) is what I have. You can see that there is an inner mesh inside the outer mesh. (b) is what I want to achieve

Hello @SimonNgj - as with your other issue, LevelSetRebuild.h or the tools in FastSweeping.h should be a good start

@SimonNgj Another method I've had success with is by adding more points inside of your geometry. Once I've converted the original set of points to a level-set, then I use one of the methods in PointScatter.h to add more points inside of the level-set. I then make another particlesToSdf call before applying the level-set operations (i.e. dilation, smoothing, and erosion) you mentioned.
