Q&A

• How do I save & load multiple meshes/labels to my STL file?

  • It is not possible to save multiple meshes in a single STF file. Each mesh must be store in a separate file. The code below shows how to save all the meshes and use their labels (unique ID) as a base for their file names.

    STL_path = "where_do_you_want_to_save_the_STL_files";
    
    list_of_meshes = ["root"];
    
    while len(list_of_meshes):
      label = list_of_meshes.pop(0);
      if gvxr.getNumberOfPrimitives(label):
        gvxr.saveSTLfile(label, os.path.join(STL_path, label + ."stl");
    
      for i in range(gvxr.getNumberOfChildren(label)):
        list_of_meshes.append(gvxr.getChildLabel(label, i));

• My sample consists of different components made from different materials. I've created a .stl 3D model of my sample. How can I assign different materials to different parts of the 3D model via gVXR?
