[gate-users] how to get a transparent voxelized phantom?

[Richard Taschereau]

Hi Yuxuan,

In order to view transparency, you need a viewer that supports it, like the
G4RayTracer (for more info see  ...
geant4/source/visualization/RayTracer/README).  The alpha parameter controls
the transparency level: 0-transparent, 1-opaque.

Cheers,
Richard
