Hi.
I converted an existing GEANT geometry/RZ file into a ROOT macro.
for example
g2root mygeom.rz mygeom.C
To draw the geometry on Canvas I tried in the following way:
root> c1 = new TCanvas("c1","view configuration",200,10,700,500)
root> .x mygeom.C
root> mygeom.Draw()
root> c1->Update()
In some reason it does not show any geometry configuration. Just vacant
canvas appears. Do anyone have any suggestion? I will appreciate a lot!
---
Thanks,
Jayoung
p.s. Just for reference I attached "mygeom.C" here.
