Procedural 3d scan points cloud to mesh - Blender project

Reliable geometry nodes asset to convert imported 3d scan points cloud to a colored mesh. Used Blender 4.2.3

The downloadable file does not contain any mesh (points cloud data) relative to the video tutorial.

With this workflow you'll be able to manage these parameters:

• Type: You can decide to have Points, Vertices, Mesh as the result of the object.
• Cleaning section
  • Merge distance: this allows you to merge vertices to have less points in the environment maintaining a good balance with the entire final geometry. More big is the value more vertices will be merged and also the attributes.
  • Delete further: this allows you to delete points that are too far from the theoretical mesh. The vertices that will have a distance from the nearest vertex, greater than this value, will be deleted.
  • Quality less than: If you have imported a 3d scan including the quality attribute, this percentage allows you to delete the points that has a bad quality from the scan. More big is the value more vertices will be deleted.
• Points
  • Radius: this is the radius of the points shown on the viewport if you choose the Points type.
• Mesh
  • Radius: this parameter and the next allows you to find the correct melted result for the final mesh.
  • Voxel size: this parameter and the previous allows you to find the correct melted result for the final mesh.

Big tip! If you are happy with the values of the cleaning section, use the Bake node added in the geometry setup after the the Merge by distance frame to have better performances while tweaking the parameters about points and mesh.

As always you can open your project or create a new file, go to the File->Append... menu, select this file then NodeTree and then this geometry node setup. Next apply it on your imported points cloud object and voilà!
