 **Summary**: ''MeshLab'', ''Gmsh'', ''Simpleware'' are good %%GUI%% tools for simple-to-medium mesh-generation; for high-throughput tasks, use script-based ''Gmsh'', ''Netgen'', ''TetGen'', ''CGAL'', ''iso2mesh'' (all are highly flexible), and also ''ANSYS ICEM''.  **Summary**: ''MeshLab'', ''Gmsh'', ''Simpleware'' are good %%GUI%% tools for simple-to-medium mesh-generation; for high-throughput tasks, use script-based ''Gmsh'', ''Netgen'', ''TetGen'', ''CGAL'', ''iso2mesh'' (all are highly flexible), and also ''ANSYS ICEM''.

 +**Segmentation Tips** for complex / noisy data:
 +  - use machine learning tool [[http://imagej.net/Trainable_Weka_Segmentation|Weka]] in Fiji for pre-processing
 +  - use //Filter Sandbox// and //Marker-based Watershed Mask// modules in ''Amira''
