Hello,
Suppose i know a full path to the node i’m interested in. I need to get TGeoHMatrix associated to that node. The shortes way i found is
gGeoManager->GetVolume(“ALIC”)->GetNode(“Rich_7”)->GetMatrix()
Here ALIC is a mother volume of my node and Rich_7 is the node name.
I’m quite sure there must be much easier way to do this task by providing the full path
like gGeoManager->Get???(“ALIC_1/Rich_7”) but unable to figure it out.
Hi Kiril,
It is OK to retreive a LOCAL matrix like this. In this particular case it is even the same as the global one. Anyway, I hope you do not do this often…(as during Stepping). A faster way is to backup the matrix when you create it in your geometry.
Indeed, there is a :
gGeoManager->cd("ALIC_1/RICH_7);
gGeoManager->GetCurrentNode()->GetMatrix();
but this is not necessary faster or smarter… Probably just more suitable when your matrix is deeper.
Cheers,
