The LEGO Mindstorms EV3 Robot Graphics File (RGF) is a proprietary binary file format used by the LEGO Mindstorms EV3 software to store robot graphic models. It is a vector-based file format that stores information such as the robot's 3D geometry, color and other visual properties, as well as the model's connection points, used for connecting with other LEGO elements.
Created by Digital Equipment Corporation (DEC), SIXEL is a bitmap image format in an escaped sequence (seen as six pixels high and one pixel wide). You have to convert it into a more accessible format if you don’t have a DEC terminal to view it.
