S2: Step-by-step-guide using MeshLab in the work flow.
Paul Kalke, Conrad Helm
Abstract
How to do data refinements like repair, smooth and simplification in MeshLab and export as -ply-file.
Steps
•Open MeshLab
•First step is Cleaning and Repairing your mesh-irrelevant if it is generated by Image J, Amira or any other software, the steps are the same
•Often used procedures/steps:
-
Remove Duplicate Faces
-
Remove Dublicate Vertices
-
Merge Close Vertices
-
Repair non Manifold edges by…
•Just try out, the results are written in the downright white window

•Now re-mesh your label by Remeshing: Isotropic Remeshing
•You can do that multiple times but 1 or 2 is enough to change the topology of your vertices in a more regular distribution
•Result of re-meshing shown in Blender
•A smoothing step is possible here but not obligatory
• Taubin smooth or Laplacian Smooth are suitable and can be used also multiple times
•Result of 2 times Taubin Smooth shown in Blender
•Now you reduce the size by decreasing the vertices of your label/surface by Simplification: Quadric Edge Collapse Decimation
•Result of 2 times simplification shown in Blender
•Save label as .ply-file
•Repeat all described steps for each label or batch of labels by opening a new file
