Can you upload your file somewhere to see what do you mean?

Subject: [ROOT] Problem with the 3D image resolution in ROOT

Dear all,  

I'm trying to draw a 3D image of several detectors via the following codes, the geormetry of the detectors is stored in geom_mdc.root file. The program works correctly, but I find the resolution of the image rather unsatifactory. I'm wondering if there is any way I can set a higher resolution in the Draw() method, or something else. Thanks a lot for your help.

void readVol()
{
  gSystem->Load("libGeom");
  TGeoManager *geom = new TGeoManager("simple1", "Simple geometry");   geom->SetVisLevel(6);

  TFile *f=new TFile("geom_mdc.root");
  TGeoVolume *volBes = (TGeoVolume*)(f->Get("volBes"));   gGeoManager->SetTopVolume(volBes);  

  gGeoManager->CloseGeometry();
  volBes->Draw();
