[Gate-users] How to define an irregular shape

[Chen Jie]

I want to define a volume with irregular shape(e.g. polygon), but form User Guide V7.2 I can only find several given shapes with specified commands . And it says POLYGON is not yet implemented. I also learned that Geant4 can support more self-defined shapes, but I can’t figure out how to link GATE commands to GEATN4. I wonder if I can define this shape by boolean operation like TRPD or directly call GEANT4 with some sommands. Can someone tell me how to work it out? Thanks!
