Convert COB to 3DM

The COB file extension stands for Caligari trueSpace 3D Object, a proprietary format used by the trueSpace 3D modeling and animation software. Introduced by Caligari Corporation, trueSpace was popular in the 1990s and early 2000s for creating and rendering 3D graphics. COB files store 3D geometry, material properties, and other relevant details, enabling efficient optimization and rendering of 3D models. This format played a significant role in the development of 3D graphics and animation during its peak usage.

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.
