How do I make an zylon fighter, fake 3d?

Using angles we can fake sorting order of our zylon fighter. Using ellipse rendering for the cockpit we can get a very nice 3d effect. Wings are made of simple hexagons with some line rendering. Its modular.. What is a zylon fighter, fake 3d? How do you make a zylon fighter, fake 3d? This script and codes were developed by Andi Smithers on 21 November 2022, Monday.
