The following sequence of vis commands (as suggested in Sec. 3.16.7.9.4 of the User's Guide) causes segmentation fault (independent of geometry being visualized). /run/initialize /vis/open OGLSX /vis/camera/viewpoint 70 20 /vis/drawVolume Output: >> ********************************************** >> Geant4 version $Name: geant4-02-00 $ >> (30-Jun-2000) >> Copyright : Geant4 Collaboration >> ********************************************** >> Constructing Visualization Manager.... >> Initialising Visualization Manager.... >> Registering graphics systems.... >> >> G4VisManager::SetCurrentGraphicsSystem: system now OpenGLStoredX >> 1 OpenGLStoredX scenes extanct. >> New scene handler "scene-handler-0" created. >> Null string specified.

Bug recreated. Will be investigated. Thanks.
Fixed in the following tag. Should be in the next reference tag and possibly in a patch to Geant4 3.0. 1st February 2001 John Allison (vis-V03-00-01) - Fixed cause of crash when setting viewpoint before creating scene (Bug #157). Solution: SetView no longer called when view parameters are changed. In any case it's called just before drawing, whixh is the right place.
