We can search all of the filters at the MESHLAB search box, apply them with the default values unless specified.<\/p>\n\n\n\n

First we’re going to clean the point cloud<\/strong><\/h4>\n\n\n\n
  1. Remove Duplicated Faces<\/li>
  2. Remove Duplicated Vertex<\/li>
  3. Remove Zero Area Faces<\/li>
  4. Point Cloud Simplification<\/strong> (You can skip this one if you need the texture color from the vertexes as it will ad unwanted speckles)
    Number of samples try 1\/2 of the total Vertex count and increase if needed (Ex if Count is 800,000 then samples can be 400,000)
    Best Sample Heuristic<\/strong> Checked<\/li>
  5. Select the “Simplified Cloud” new mesh<\/li>
  6. Compute normals for point sets<\/strong>
    Neighbour num<\/strong> between 10 – 100
    Smooth Iteration<\/strong> between 0 – 10<\/li>
  7. Show Normal<\/strong>
    Make sure Normals are Computed properly<\/li><\/ol>\n\n\n\n

    Now to Create the solid Mesh<\/h4>\n\n\n\n
    1. Screened Poisson Surface Reconstruction<\/strong><\/li>
    2. Select Faces with edges longer than<\/strong>
      Then delete those faces<\/li>
    3. Remove isolated pieces (wrt Face Num.)<\/strong>.
      Remove unreferenced vertices<\/strong> Checked<\/li>
    4. Select non Manifold Vertices<\/strong>
      Delete them<\/li>
    5. Laplacian Smooth (In case is needed)<\/li><\/ol>\n\n\n\n

      Now for Texturing<\/h4>\n\n\n\n
      1. Per Vertex Texture Function<\/strong><\/li>
      2. Convert PerVertex UV into PerWedge UV<\/strong><\/li>
      3. Parametrization: trivial Per-triangle<\/strong>
        Quads -per -line : 0
        Texture Dimension (px) : 4096 or (1024, 2048).
        Inter-triangle border (px) : 0
        Method : Basic (with Space-optimizing somethimes Meshlab crashes.)<\/li>
      4. Save Project As..<\/strong>. Save the project in “.mlp”<\/li>
      5. Export Mesh As..<\/strong>. OBJ
        TexCoord<\/strong> Checked<\/li>
      6. Transfer: Vertex Color to Texture<\/strong>
        Texture file : Same name as the mesh
