[Gate-users] About simulation speed

[Qiyong Fan]

Dear All,

I use openGL to watch the process of simulation for voxelized phantom and
source. I found out one problem. The following range.dat is the one I use to
change the Interfile Image values into materials of the phantom. The word
"true" is supposed to define whether we can visualize the phantom or not.
However, if I change it to be faulse, not only I cannot see the phantom, but
also the simulation speed is also significantly improved as indicated by
openGL viewers. Does anybody know why is this?
