[Gate-users] 答复: [Issue: CT simulation with GPU]

[王小状]

Dear all users,
       Glad to talk to you .
My name is Xiaozhuang Wang, i  am a student of  University of Science and technology of China, and  I started to learn the PET simulation by vGate 7.2.
At beginning of geometry, I met a little trouble about visualization. The error came out if I use any visualization command such as :
/vis/open OGL  or /vis/open OGLSX :
