I am trying to develop a complete STL file Viewer which use PyROOT and OpenGL.
After some researchs i found the triangleset tutorial : TEveTriangleSet Tutorial.
I tried to adapt it with python code (still using the same file as the tutorial : “broken_torus.tring”) but the viewer do not display.
Here is a MWE of my code :
import ROOT import time eveManager = ROOT.TEveManager(800,400) triangleSet = ROOT.TEveTriangleSet.ReadTrivialFile("/usr/share/doc/root/tutorials/eve/broken_torus.tring") triangleSet.SetName("test") triangleSet.GenerateTriangleNormals() triangleSet.GenerateRandomColors() triangleSet.SetMainColor(0) eveManager.AddElement(triangleSet) eveManager.Redraw3D() while triangleSet: time.sleep(1)
Currently, i have two tracks :
- I have to configure correctly the
eveManagerbut i found no information in the root user guide (User guide)
triangleset.ctutorial use a
gEvefield/instance (available at triangleSetTutorial and gEveLink) and i have no idea how to access it and what it is supposed to be.
Can you help me figure out where i did a mistake ?
Is there a better approach or another class, that could be better for my purpose of developping a *.stl/*.tring file viewer ?
