Some of you may have heard about .dae file formats. They count as images, but you are able to drag, zoom and pan them like in the SimplePlanes Builder. They work on web-pages and are fully colour! I think this would be good for the website because, instead of taking snapshots, you can simply just drag around!
Also, you can save them like normal images, and it is possible to convert them into .obj, or other 3D files, therefore allowing anyone to print the planes directly from the website!
