Detailed Description

Shows CMS geometry in stereo mode.

This requires quad-buffer support in the OpenGL hardware / driver, otherwise a fatal error occurs.

void geom_cms_stereo(Bool_t quad_buf=kTRUE)
gGeoManager = gEve->GetGeometry("http://root.cern.ch/files/cms.root");
auto top = gGeoManager->GetTopVolume()->FindNode("CMSE_1")->GetVolume();
auto trk = new TEveGeoTopNode(gGeoManager, top->FindNode("TRAK_1"));
auto calo = new TEveGeoTopNode(gGeoManager, top->FindNode("CALO_1"));
auto muon = new TEveGeoTopNode(gGeoManager, top->FindNode("MUON_1"));
// --- Stereo ---
TEveWindowSlot* slot = 0;
auto sv = new TEveViewer("Stereo GL", "Stereoscopic view");
sv->SpawnGLViewer(gEve->GetEditor(), kTRUE, quad_buf);
// --- Redraw ---
// --- Fix editor ---
// EClipType not exported to CINT (see TGLUtil.h):
// 0 - no clip, 1 - clip plane, 2 - clip box
v->SetGuideState(TGLUtil::kAxesEdge, kTRUE, kFALSE, 0);
v->CurrentCamera().RotateRad(-1.2, 0.5);
