Hi
I wanted to ask what the recommended way is to add some kind of mirroring to a volume.
I assumed it would be through some kind of transformation but only saw that TGeoHMatrix has ReflectX …Y , …Z functions while also stating that they shouldn’t be used for node definitions (here first lines). Further addNode seems to be the way to apply transformation to volume.
here is written that reflections are allowed (ctrl F Reflection first occurence)
Did i miss something?
Best regards
Hi,
Could you be a bit more precise? What volume you want to mirror and how? Adding in the loop @agheata
D
quite general, i have a volume that represents some kind of sensor, containing other volumes, build up in a certain way. I would like to use this sensor mockup again just mirrored around a certain plane and thought i could do so by applying a transformation to the volume or when adding it as node to a parentvolume.
more explicitly given the codestructure i would like to know what the recommended way is to do the flip
in the meantime i’ve found TGeoScale that also has ReflectX …Y , …Z functions and i assume i’m just supposed to use that but how would i combine it with rotations and translations without creating a TGeoHMatrix?
sensor_volume = get_sensor(...)
diag = r.TGeoScale()
diag.ReflectZ(True,True)
somerotation= ...
#this would create TGeoHMatrix
parentvolume.addNode(sensor_volume,some_id,somerotation*diag)
