About this 3D model

UPDATE: I am taking important exams now and so I will be unable to add any more files. My entry for the Polypanel competition is a series of panels based on different aspects of our planet Earth. Each panel's feature was modeled by me in Virtual Reality and then exported to another software for slight editing and placement of polypanel From landscapes to man-made structures, these panels can be combined to form a geometric sphere (or kept flat for you flat-earthers out there!). Create your own planet! Note:I will be adding more entries to this over the course of the competition, so if you have any suggestion please leave a comment. Edit:Added the Crater file. Added Pyramid file.Added Factory file.
