  1. DAWN

  2. DAWN • DAWN is a vectorized 3D PostScript processor developed at the Fukui University • Well suited to prepare high quality outputs for presentation and/or documentation • Useful for detector geometry debugging (it comes with a facility, DAVID, which allows to detect overlapping volumes) • Remote visualization, cut view, off-line re-visualization are supported by DAWN • A DAWN process is automatically invoked as a co-process of Geant4 when visualization is performed and 3D data is passed with inter-process communication via a file or the TCP/IP socket

  3. DAWN (2) • There are two kinds of DAWN drivers • DAWN-File • DAWN-Network • The DAWN-File driver send 3D data to DAWN via an intermediate file (called g4.prim) in the current directory. The contents of the file can be re-visualized (without running Geant4) by simply running DAWN on it dawn g4.prim • The DAWN-Network driver send 3D data to DAWN via the TCP/IP socket or the named pipe and it can be used to perform remote visualization • If you have no network, set the environment variable G4DAWN_NAMED_PIPE to 1, to switch the default socket connection to the named pipe within the same host machine
