1) Using a CAD/3D software
Export your CAD/3D file as JPG/JPEG image frames. We recommend from 100-200 image frames from different angles for better results.
2) Recording your own videos
It is possible to create professional and inexpensive videos using your smartphone or camera. We recommend a high-resolution camera (most of smart phones have it today), a spinner, a mini tripod compatible to your phone and a light box. Everything can be bought online on Amazon, for example.
