Iso2Mesh 2018 (v1.9.0-1)

Iso2Mesh 2018 (1.9.0-1, codename: Century Egg) is a milestone towards the 2.0 release. It now contains the source codes and makefiles to compile the embedded open-source meshing utilities to binary - so that Linux package maintainers can distribute Iso2Mesh via the software repository without concerning the licenses of the embedded binary tools. Further more, it adds a number of new features, such as extruding curves to form surfaces, importing/exporting NIRFAST files, mesh interpolations, as well as increased robustness in surface boolean, surf2mesh etc.

A number of modules received updates - JSONLab was updated to 1.8, tetgen got a Windows binary for 1.5.1, meshfix's windows binary was also upgraded to v2.1.

Iso2Mesh 2017 (v1.8) Release Note

Iso2mesh 2017 is a maintenance release. It contains a number of exciting new features and a range of bug fixes.

The most important update is a robust surface boolean operator (surfboolean) based on the open-source utility Cork. It replaces the previously included libGTS utilities. We also added a number of new functions, such as insurface, fillsurf, innersurf, and outersurf etc. The JSONlab toolbox was also updated to the latest release v1.5.

The detailed ChangeLog is listed below:

    1.**robust surface boolean operator based on Cork
    2. update tetgen 1.5 to 1.5.1
    3. new function: insurface for point-in-surface test
    4.*new function: fillsurf for tesselating a closed surface
    5. new function: surfvolume for calculating the volume of an enclosed surface
    6.*new function: innersurf/outersurf: interior and exterior parts of a surface
    7. meshcylinders supports a series of segments, also returns PLC
    8. surfedge/volface return tet element id for the face triangles
    9. plotmesh supports element-based colormap
   10. s2v outputs mesh-to-voxel transformation matrix
   11.*JSONlab updates to 1.5 Nominus alpha
   12. display binary utility download URL when missing
   13. faceneighbor returns row- or column-major facelist
   14. fix half-voxel offset bug in cgalmesher
   15. surf2vol and s2v now rasterize labeled surfaces and tetrahedral mesh
   16. disable binary compression for Mac OS to avoid crashes
   17. fix uniqedges edgemap output bug
