S2: Step-by-step-guide using MeshLab in the work flow.

Abstract

How to do data refinements like repair, smooth and simplification in MeshLab and export as -ply-file.

•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:

•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
