"import setuptools not found"

Please install Pip in order to install the MDsrv. It needs to be installed in advance to add underlying tools.

How do I install the development version?

Change within the terminal into the MDsrv repository. Execute setup.py with the install flag. If you want to see live changes of the code, link it by using the develop flag. Make sure that you have all needed rights.

python setup.py install|develop

Which browsers support NGL/WebGL?

The NGL Viewer requires your browser to support WebGL. To see if your browser supports WebGL and what you might need to do to activate it, visit the Get WebGL page.

Generally, WebGL is available in recent browser versions of Mozilla Firefox (>29) or Google Chrome (>27). The Internet Explorer supports WebGL only since version 11. The Safari Browser since version 8 (though WebGL can be activated in earlier version: first enable the Develop menu in Safari’s Advanced preferences, then secondly in the now visible Develop menu enable WebGL).

See also this page for details on which graphics card drivers are supported by the browsers.

How to get a smoother appearance (using __WebGL draft extensions__)?

For a smoother appearance of cylinders and spheres your browser needs to have the EXT_frag_depth extension available. The WebGL Report should list the extension if active. If not, you can enable WebGL draft extensions in your browser following these instructions:

  • Chrome: browse to about:flags, enable the Enable WebGL Draft Extensions option, then relaunch.
  • Firefox: browse to about:config and set webgl.enable-draft-extensions to true.
  • Safari: Currently, the EXT_frag_depth extension is not supported.
  • Internet Explorer: Currently, the EXT_frag_depth extension is not supported.
