[Gate-users] Rotation of a gps source

[Didier Benoit]

Hi Ida,

In Gate v5.0 you can't rotate a source. In Gate v6.1 we have implemented 
the two lines:
/gate/source/[source name]/setRotationAxis 1 0 0
/gate/source/[source name]/setRotationAngle 90 deg

In Gate v5.0, I computed at each time and for each run the position of 
the source in the space. Unfortunately Geant4 doesn't provide a rotation 
of the source too.

King regards,
Didier Benoit
