[OC]Opacity slider and fade background 3D transparent globe

Few weeks back I published the poor version of this simulation. Thanks to all the feedback I got today is a better simulation. I believe iterations and review can help to
Improve. Programming is not my background so I learn as I do 😊😊😊thanks to all and special thanks to the person in Japan 🇯🇵
