#################################################################################################### # # Invoking X3D model self-test: # # $ python VisibleShapesTest.py # # Python package x3d.py package is available on PyPI for import. # This approach simplifies Python X3D deployment and use. # https://pypi.org/project/x3d # # Installation: # pip install x3d # or # python -m pip install x3d # # Developer options for loading x3d package in other Python programs: # # from x3d import * # preferred approach, terser source that avoids x3d.* class prefixes # # or # import x3d # traditional way to subclass x3d package, all classes require x3d.* prefix, # # but python source is very verbose, for example x3d.Material x3d.Shape etc. # # X3dToPython.xslt stylesheet insertPackagePrefix=true supports this option. # # Project home page: # X3D Python Scene Access Interface Library (X3DPSAIL) # # https://www.web3d.org/x3d/stylesheets/python/python.html #
