Re: Geometry questions

Hi Akira,
Q1. That's an issue with the 3D GL driver on your box, I am not an expert but I added one in CC

Q2. Just call gGeoManager->SetVisLevel(5) (default is 3). This will also disable the feature limiting the number of nodes to be displayed (default 10K)

Q3. No error, just define a color also for mapmtBackObs

Cheers, Andrei

P.S. Avoid AddNodeOverlap which is penalizing in tracking speed and can hide real geometry problems.

However, if I uncomment the line 78, 151 MAPMTs are drawn as expected. ROOT cannot draw more than 151 MAPMTs in this script. How can I draw all MAPMTs?
