Convert NFF to OBJ

The Neutral File Format (NFF) is a minimal scene description language used in computer graphics for testing rendering algorithms and efficiency schemes. Developed in the 1990s, NFF provides a structured way to define 3D geometric objects, surface properties, lighting placement, and viewing angles. It is primarily utilized in ray tracing applications and procedural databases, enabling interoperability between different rendering systems. While originally designed for algorithm evaluation, NFF has influenced the development of more advanced scene description formats. Its simplicity and ASCII-based structure make it a practical choice for quick data exchange in 3D modeling environments.

The OBJ (Object) file extension, related to Wavefront 3D Object, is a standard 3D image format developed by Wavefront Technologies. It is widely used for representing 3D geometry, including the position of vertices, texture coordinates, and normals. OBJ files are versatile and commonly employed in various CAD, 3D printing, and computer graphics applications due to their simplicity and compatibility with numerous 3D modeling programs. Introduced in the 1980s, the OBJ format has become a cornerstone in the industry, facilitating easy exchange and rendering of 3D models across different platforms.
