special wireframe cube

Hi, I met with an application draw cube(please refer the image below) like this, I think it’s really clever but I cannot do that~

The cube is wireframe and transparent without displaying the back wire!!

Would u please explain me how to get this result or provide some tips for me~~

Thanks a lot!
best regards!

Maybe back culling?
