Convert LWS to 3DM

The LWS (LightWave 3D Scene) file extension is used by LightWave 3D, a 3D modeling, animation, and rendering software developed by NewTek and now maintained by LightWave Digital. An LWS file contains scene information, including object positions, camera settings, and references to other files like LWO (LightWave 3D Object) files. It is primarily used in industries such as TV, film, architecture, advertising, and video game development. The format allows for easy editing and portability of 3D scenes.

The 3DM file extension, standing for "3D Model", is associated with the openNURBS initiative, which facilitates the exchange of 3D geometry across CAD, CAM, CAE, and computer graphics software. Developed by Robert McNeel & Associates, it serves as the native format for Rhinoceros (Rhino) software. Introduced to address interoperability challenges, 3DM files store precise 3D models using NURBS (Non-Uniform Rational B-Splines) and polygon mesh representations. This format is widely adopted due to its open-source nature, enabling developers to read and write 3DM files without proprietary restrictions, thus promoting seamless data sharing in 3D modeling workflows.
