I am developping a program with pyroot visualisation, and when i ask for draw, only leaves are visible (according to the anology with trees).
I found in the documentation (Geometry documentation; section 20.7.1) if i want to force representation of all volumes i have to put :
However medium volumes (= branch) are not drawn.
I put a MWE :
import ROOT import time geoManager = ROOT.TGeoManager("Toto","toto") # Create 3 volumes tubeShape = ROOT.TGeoTube(0.,10.,10.) tube = ROOT.TGeoVolume("Pepito", tubeShape) cubeShape = ROOT.TGeoBBox(2.,2.,2.) cube = ROOT.TGeoVolume("Pepita", cubeShape) sphereShape = ROOT.TGeoSphere(0.,1.) sphere = ROOT.TGeoVolume("Pepignito", sphereShape) # Create the tree like : Tube > Cube > Sphere tube.AddNode(cube,1) cube.AddNode(sphere,1) #Configure geoManager geoManager.SetTopVolume(tube) geoManager.CloseGeometry() tube.SetLineColor(8) geoManager.SetVisLevel(10) geoManager.SetVisOption(0) geoManager.SetTopVisible() # Draw tube.Draw() while tube: time.sleep(1)
Can you help me figure out where i did a mistake ?
