Yes, there is. At one point, I needed reliable (which was, back then, almost synonymous with written-by-myself) code for computing strain; I had problems with CPM constitutive law and suspected that the incremental formulation of SCG might be the cause. It is not so much slower than SCG (IIRC). > Q2.

It was written by a guy named Olivier Galizzi and his code is way to hell; I will remove it right away so that you are not temped. Seriously. See http://www.vtk.org/doc/nightly/html/classvtkMarchingCubes.html , that will work. We are already using VTK in VTKRecorder, I will be using it for triangulation, so no problem with dependencies. (You just have to compile with the 'vtk' feature and add YADE_REQUIRE_FEATURE(vtk) to your .cpp file). _______________________________________________ Mailing list: https://launchpad.net/~yade-users Post to : [email protected] Unsubscribe : https://launchpad.net/~yade-users More help : https://help.launchpad.net/ListHelp
