sci-physics Geant simulates the passage of subatomic particles through matter, for instance, particle detectors. Geant 3 simulations are performed by linking Fortran code supplied by the user with the Geant libraries, then running the resulting executable. This package includes gxint, the script used to perform this linking step. Geant 4 is a complete rewrite in C++ with addition of other modern features and detectors. Enable the MIT Athena (x11-libs/libXaw) widget set (default is Motif) Add a lot of standard physics data files for geant4 Add support for media-gfx/dawn (3D postscript rendering) Enable geometry markup language for xml Add compatibility for geant321 to geant4 Produce a huge global library instead of small ones Produce many small libraries instead of global ones Add support for Abstract Interfaces for Data Analysis Add support for media-libs/openinventor SGI toolkit Enable raytracing for physics events Enable output of geant4 in vrml formats
