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.
The sk2 file type is a vector graphic format created by the sK1 open source vector graphics editor. It is an extension of the sk1 format and is used to store vector graphics and images. The sk2 file format supports layers, masking, transparency, and other advanced features.
